It is backward-compatible with the current + OpenGL Utilities tesselator, and is intended to replace it. Here is + a summary of the major differences: + + - input contours can be intersecting, self-intersecting, or degenerate. + + - supports a choice of several winding rules for determining which parts + of the polygon are on the "interior". This makes it possible to do + CSG operations on polygons. + + - boundary extraction: instead of tesselating the polygon, returns a + set of closed contours which separate the interior from the exterior. + + - returns the output as a small number of triangle fans and strips, + rather than a list of independent triangles (when possible). + + - output is available as an explicit mesh (a quad-edge structure), + in addition to the normal callback interface. + + - the algorithm used is extremely robust. + + +The interface +------------- + + The tesselator state is maintained in a "tesselator object". + These are allocated and destroyed using + + GLUtesselator *gluNewTess( void ); + void gluDeleteTess( GLUtesselator *tess ); + + Several tesselator objects may be used simultaneously. + + Inputs + ------ + + The input contours are specified with the following routines: + + void gluTessBeginPolygon( GLUtesselator *tess ); + void gluTessBeginContour( GLUtesselator *tess ); + void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data ); + void gluTessEndContour( GLUtesselator *tess ); + void gluTessEndPolygon( GLUtesselator *tess ); + + Within each BeginPolygon/EndPolygon pair, there can be zero or more + calls to BeginContour/EndContour. Within each contour, there are zero + or more calls to gluTessVertex(). The vertices specify a closed + contour (the last vertex of each contour is automatically linked to + the first). + + "coords" give the coordinates of the vertex in 3-space. For useful + results, all vertices should lie in some plane, since the vertices + are projected onto a plane before tesselation. "data" is a pointer + to a user-defined vertex structure, which typically contains other + information such as color, texture coordinates, normal, etc. It is + used to refer to the vertex during rendering. + + The library can be compiled in single- or double-precision; the type + GLUcoord represents either "float" or "double" accordingly. The GLU + version will be available in double-precision only. Compile with + GLU_TESS_API_FLOAT defined to get the single-precision version. + + When EndPolygon is called, the tesselation algorithm determines + which regions are interior to the given contours, according to one + of several "winding rules" described below. The interior regions + are then tesselated, and the output is provided as callbacks. + + + Rendering Callbacks + ------------------- + + Callbacks are specified by the client using + + void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)()); + + If "fn" is NULL, any previously defined callback is discarded. + + The callbacks used to provide output are: /* which == */ + + void begin( GLenum type ); /* GLU_TESS_BEGIN */ + void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */ + void vertex( void *data ); /* GLU_TESS_VERTEX */ + void end( void ); /* GLU_TESS_END */ + + Any of the callbacks may be left undefined; if so, the corresponding + information will not be supplied during rendering. + + The "begin" callback indicates the start of a primitive; type is one + of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the + notes on "boundary extraction" below). + + It is followed by any number of "vertex" callbacks, which supply the + vertices in the same order as expected by the corresponding glBegin() + call. After the last vertex of a given primitive, there is a callback + to "end". + + If the "edgeFlag" callback is provided, no triangle fans or strips + will be used. When edgeFlag is called, if "flag" is GL_TRUE then each + vertex which follows begins an edge which lies on the polygon boundary + (ie. an edge which separates an interior region from an exterior one). + If "flag" is GL_FALSE, each vertex which follows begins an edge which lies + in the polygon interior. "edgeFlag" will be called before the first + call to "vertex". + + Other Callbacks + --------------- + + void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */ + + - Returns an explicit mesh, represented using the quad-edge structure + (Guibas/Stolfi '85). Other implementations of this interface might + use a different mesh structure, so this is available only only as an + SGI extension. When the mesh is no longer needed, it should be freed + using + + void gluDeleteMesh( GLUmesh *mesh ); + + There is a brief description of this data structure in the include + file "mesh.h". For the full details, see L. Guibas and J. Stolfi, + Primitives for the manipulation of general subdivisions and the + computation of Voronoi diagrams, ACM Transactions on Graphics, + 4(2):74-123, April 1985. For an introduction, see the course notes + for CS348a, "Mathematical Foundations of Computer Graphics", + available at the Stanford bookstore (and taught during the fall + quarter). + + void error( GLenum errno ); /* GLU_TESS_ERROR */ + + - errno is one of GLU_TESS_MISSING_BEGIN_POLYGON, + GLU_TESS_MISSING_END_POLYGON, + GLU_TESS_MISSING_BEGIN_CONTOUR, + GLU_TESS_MISSING_END_CONTOUR, + GLU_TESS_COORD_TOO_LARGE, + GLU_TESS_NEED_COMBINE_CALLBACK + + The first four are obvious. The interface recovers from these + errors by inserting the missing call(s). + + GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded + the predefined constant GLU_TESS_MAX_COORD in absolute value, and + that the value has been clamped. (Coordinate values must be small + enough so that two can be multiplied together without overflow.) + + GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an + intersection between two edges in the input data, and the "combine" + callback (below) was not provided. No output will be generated. + + + void combine( GLUcoord coords[3], void *data[4], /* GLU_TESS_COMBINE */ + GLUcoord weight[4], void **outData ); + + - When the algorithm detects an intersection, or wishes to merge + features, it needs to create a new vertex. The vertex is defined + as a linear combination of up to 4 existing vertices, referenced + by data[0..3]. The coefficients of the linear combination are + given by weight[0..3]; these weights always sum to 1.0. All vertex + pointers are valid even when some of the weights are zero. + "coords" gives the location of the new vertex. + + The user must allocate another vertex, interpolate parameters + using "data" and "weights", and return the new vertex pointer in + "outData". This handle is supplied during rendering callbacks. + For example, if the polygon lies in an arbitrary plane in 3-space, + and we associate a color with each vertex, the combine callback might + look like this: + + void myCombine( GLUcoord coords[3], VERTEX *d[4], + GLUcoord w[4], VERTEX **dataOut ) + { + VERTEX *new = new_vertex(); + + new->x = coords[0]; + new->y = coords[1]; + new->z = coords[2]; + new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r; + new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g; + new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b; + new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a; + *dataOut = new; + } + + If the algorithm detects an intersection, then the "combine" callback + must be defined, and must write a non-NULL pointer into "dataOut". + Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no + output is generated. This is the only error that can occur during + tesselation and rendering. + + + Control over Tesselation + ------------------------ + + void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value ); + + Properties defined: + + - GLU_TESS_WINDING_RULE. Possible values: + + GLU_TESS_WINDING_ODD + GLU_TESS_WINDING_NONZERO + GLU_TESS_WINDING_POSITIVE + GLU_TESS_WINDING_NEGATIVE + GLU_TESS_WINDING_ABS_GEQ_TWO + + The input contours parition the plane into regions. A winding + rule determines which of these regions are inside the polygon. + + For a single contour C, the winding number of a point x is simply + the signed number of revolutions we make around x as we travel + once around C (where CCW is positive). When there are several + contours, the individual winding numbers are summed. This + procedure associates a signed integer value with each point x in + the plane. Note that the winding number is the same for all + points in a single region. + + The winding rule classifies a region as "inside" if its winding + number belongs to the chosen category (odd, nonzero, positive, + negative, or absolute value of at least two). The current GLU + tesselator implements the "odd" rule. The "nonzero" rule is another + common way to define the interior. The other three rules are + useful for polygon CSG operations (see below). + + - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero). + + If TRUE, returns a set of closed contours which separate the + polygon interior and exterior (rather than a tesselation). + Exterior contours are oriented CCW with respect to the normal, + interior contours are oriented CW. The GLU_TESS_BEGIN callback + uses the type GL_LINE_LOOP for each contour. + + - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0. + + This specifies a tolerance for merging features to reduce the size + of the output. For example, two vertices which are very close to + each other might be replaced by a single vertex. The tolerance + is multiplied by the largest coordinate magnitude of any input vertex; + this specifies the maximum distance that any feature can move as the + result of a single merge operation. If a single feature takes part + in several merge operations, the total distance moved could be larger. + + Feature merging is completely optional; the tolerance is only a hint. + The implementation is free to merge in some cases and not in others, + or to never merge features at all. The default tolerance is zero. + + The current implementation merges vertices only if they are exactly + coincident, regardless of the current tolerance. A vertex is + spliced into an edge only if the implementation is unable to + distinguish which side of the edge the vertex lies on. + Two edges are merged only when both endpoints are identical. + + + void gluTessNormal( GLUtesselator *tess, + GLUcoord x, GLUcoord y, GLUcoord z ) + + - Lets the user supply the polygon normal, if known. All input data + is projected into a plane perpendicular to the normal before + tesselation. All output triangles are oriented CCW with + respect to the normal (CW orientation can be obtained by + reversing the sign of the supplied normal). For example, if + you know that all polygons lie in the x-y plane, call + "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons. + + - If the supplied normal is (0,0,0) (the default value), the + normal is determined as follows. The direction of the normal, + up to its sign, is found by fitting a plane to the vertices, + without regard to how the vertices are connected. It is + expected that the input data lies approximately in plane; + otherwise projection perpendicular to the computed normal may + substantially change the geometry. The sign of the normal is + chosen so that the sum of the signed areas of all input contours + is non-negative (where a CCW contour has positive area). + + - The supplied normal persists until it is changed by another + call to gluTessNormal. + + + Backward compatibility with the GLU tesselator + ---------------------------------------------- + + The preferred interface is the one described above. The following + routines are obsolete, and are provided only for backward compatibility: + + typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */ + + void gluBeginPolygon( GLUtesselator *tess ); + void gluNextContour( GLUtesselator *tess, GLenum type ); + void gluEndPolygon( GLUtesselator *tess ); + + "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or + GLU_UNKNOWN. It is ignored by the current GLU tesselator. + + GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined + as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END, + GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG. + + +Polygon CSG operations +---------------------- + + The features of the tesselator make it easy to find the union, difference, + or intersection of several polygons. + + First, assume that each polygon is defined so that the winding number + is 0 for each exterior region, and 1 for each interior region. Under + this model, CCW contours define the outer boundary of the polygon, and + CW contours define holes. Contours may be nested, but a nested + contour must be oriented oppositely from the contour that contains it. + + If the original polygons do not satisfy this description, they can be + converted to this form by first running the tesselator with the + GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of + contours satisfying the restriction above. By allocating two + tesselator objects, the callbacks from one tesselator can be fed + directly to the input of another. + + Given two or more polygons of the form above, CSG operations can be + implemented as follows: + + Union + Draw all the input contours as a single polygon. The winding number + of each resulting region is the number of original polygons + which cover it. The union can be extracted using the + GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules. + Note that with the nonzero rule, we would get the same result if + all contour orientations were reversed. + + Intersection (two polygons at a time only) + Draw a single polygon using the contours from both input polygons. + Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this + winding rule looks at the absolute value, reversing all contour + orientations does not change the result.) + + Difference + + Suppose we want to compute A \ (B union C union D). Draw a single + polygon consisting of the unmodified contours from A, followed by + the contours of B,C,D with the vertex order reversed (this changes + the winding number of the interior regions to -1). To extract the + result, use the GLU_TESS_WINDING_POSITIVE rule. + + If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an + alternative to reversing the vertex order is to reverse the sign of + the supplied normal. For example in the x-y plane, call + gluTessNormal( tess, 0.0, 0.0, -1.0 ). + + +Performance +----------- + + The tesselator is not intended for immediate-mode rendering; when + possible the output should be cached in a user structure or display + list. General polygon tesselation is an inherently difficult problem, + especially given the goal of extreme robustness. + + The implementation makes an effort to output a small number of fans + and strips; this should improve the rendering performance when the + output is used in a display list. + + Single-contour input polygons are first tested to see whether they can + be rendered as a triangle fan with respect to the first vertex (to + avoid running the full decomposition algorithm on convex polygons). + Non-convex polygons may be rendered by this "fast path" as well, if + the algorithm gets lucky in its choice of a starting vertex. + + For best performance follow these guidelines: + + - supply the polygon normal, if available, using gluTessNormal(). + This represents about 10% of the computation time. For example, + if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1). + + - render many polygons using the same tesselator object, rather than + allocating a new tesselator for each one. (In a multi-threaded, + multi-processor environment you may get better performance using + several tesselators.) + + +Comparison with the GLU tesselator +---------------------------------- + + On polygons which make it through the "fast path", the tesselator is + 3 to 5 times faster than the GLU tesselator. + + On polygons which don't make it through the fast path (but which don't + have self-intersections or degeneracies), it is about 2 times slower. + + On polygons with self-intersections or degeneraces, there is nothing + to compare against. + + The new tesselator generates many more fans and strips, reducing the + number of vertices that need to be sent to the hardware. + + Key to the statistics: + + vert number of input vertices on all contours + cntr number of input contours + tri number of triangles in all output primitives + strip number of triangle strips + fan number of triangle fans + ind number of independent triangles + ms number of milliseconds for tesselation + (on a 150MHz R4400 Indy) + + Convex polygon examples: + +New: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.0459 ms +Old: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.149 ms +New: 4 vert, 1 cntr, 2 tri, 0 strip, 1 fan, 0 ind, 0.0459 ms +Old: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.161 ms +New: 36 vert, 1 cntr, 34 tri, 0 strip, 1 fan, 0 ind, 0.153 ms +Old: 36 vert, 1 cntr, 34 tri, 0 strip, 0 fan, 34 ind, 0.621 ms + + Concave single-contour polygons: + +New: 5 vert, 1 cntr, 3 tri, 0 strip, 1 fan, 0 ind, 0.052 ms +Old: 5 vert, 1 cntr, 3 tri, 0 strip, 0 fan, 3 ind, 0.252 ms +New: 19 vert, 1 cntr, 17 tri, 2 strip, 2 fan, 1 ind, 0.911 ms +Old: 19 vert, 1 cntr, 17 tri, 0 strip, 0 fan, 17 ind, 0.529 ms +New: 151 vert, 1 cntr, 149 tri, 13 strip, 18 fan, 3 ind, 6.82 ms +Old: 151 vert, 1 cntr, 149 tri, 0 strip, 3 fan, 143 ind, 2.7 ms +New: 574 vert, 1 cntr, 572 tri, 59 strip, 54 fan, 11 ind, 26.6 ms +Old: 574 vert, 1 cntr, 572 tri, 0 strip, 31 fan, 499 ind, 12.4 ms + + Multiple contours, but no intersections: + +New: 7 vert, 2 cntr, 7 tri, 1 strip, 0 fan, 0 ind, 0.527 ms +Old: 7 vert, 2 cntr, 7 tri, 0 strip, 0 fan, 7 ind, 0.274 ms +New: 81 vert, 6 cntr, 89 tri, 9 strip, 7 fan, 6 ind, 3.88 ms +Old: 81 vert, 6 cntr, 89 tri, 0 strip, 13 fan, 61 ind, 2.2 ms +New: 391 vert, 19 cntr, 413 tri, 37 strip, 32 fan, 26 ind, 20.2 ms +Old: 391 vert, 19 cntr, 413 tri, 0 strip, 25 fan, 363 ind, 8.68 ms + + Self-intersecting and degenerate examples: + +Bowtie: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.483 ms +Star: 5 vert, 1 cntr, 5 tri, 0 strip, 0 fan, 5 ind, 0.91 ms +Random: 24 vert, 7 cntr, 46 tri, 2 strip, 12 fan, 7 ind, 5.32 ms +Font: 333 vert, 2 cntr, 331 tri, 32 strip, 16 fan, 3 ind, 14.1 ms +: 167 vert, 35 cntr, 254 tri, 8 strip, 56 fan, 52 ind, 46.3 ms +: 78 vert, 1 cntr, 2675 tri, 148 strip, 207 fan, 180 ind, 243 ms +: 12480 vert, 2 cntr, 12478 tri, 736 strip,1275 fan, 5 ind, 1010 ms diff --git a/src/kits/opengl/glu/libtess/alg-outline b/src/kits/opengl/glu/libtess/alg-outline new file mode 100644 index 0000000000..d1b725a2e3 --- /dev/null +++ b/src/kits/opengl/glu/libtess/alg-outline @@ -0,0 +1,229 @@ +/* +** $Header: /cvs/mesa/Mesa/src/glu/sgi/libtess/alg-outline,v 1.1 2001/03/17 00:25:41 brianp Exp $ +*/ + +This is only a very brief overview. There is quite a bit of +additional documentation in the source code itself. + + +Goals of robust tesselation +--------------------------- + +The tesselation algorithm is fundamentally a 2D algorithm. We +initially project all data into a plane; our goal is to robustly +tesselate the projected data. The same topological tesselation is +then applied to the input data. + +Topologically, the output should always be a tesselation. If the +input is even slightly non-planar, then some triangles will +necessarily be back-facing when viewed from some angles, but the goal +is to minimize this effect. + +The algorithm needs some capability of cleaning up the input data as +well as the numerical errors in its own calculations. One way to do +this is to specify a tolerance as defined above, and clean up the +input and output during the line sweep process. At the very least, +the algorithm must handle coincident vertices, vertices incident to an +edge, and coincident edges. + + +Phases of the algorithm +----------------------- + +1. Find the polygon normal N. +2. Project the vertex data onto a plane. It does not need to be + perpendicular to the normal, eg. we can project onto the plane + perpendicular to the coordinate axis whose dot product with N + is largest. +3. Using a line-sweep algorithm, partition the plane into x-monotone + regions. Any vertical line intersects an x-monotone region in + at most one interval. +4. Triangulate the x-monotone regions. +5. Group the triangles into strips and fans. + + +Finding the normal vector +------------------------- + +A common way to find a polygon normal is to compute the signed area +when the polygon is projected along the three coordinate axes. We +can't do this, since contours can have zero area without being +degenerate (eg. a bowtie). + +We fit a plane to the vertex data, ignoring how they are connected +into contours. Ideally this would be a least-squares fit; however for +our purpose the accuracy of the normal is not important. Instead we +find three vertices which are widely separated, and compute the normal +to the triangle they form. The vertices are chosen so that the +triangle has an area at least 1/sqrt(3) times the largest area of any +triangle formed using the input vertices. + +The contours do affect the orientation of the normal; after computing +the normal, we check that the sum of the signed contour areas is +non-negative, and reverse the normal if necessary. + + +Projecting the vertices +----------------------- + +We project the vertices onto a plane perpendicular to one of the three +coordinate axes. This helps numerical accuracy by removing a +transformation step between the original input data and the data +processed by the algorithm. The projection also compresses the input +data; the 2D distance between vertices after projection may be smaller +than the original 2D distance. However by choosing the coordinate +axis whose dot product with the normal is greatest, the compression +factor is at most 1/sqrt(3). + +Even though the *accuracy* of the normal is not that important (since +we are projecting perpendicular to a coordinate axis anyway), the +*robustness* of the computation is important. For example, if there +are many vertices which lie almost along a line, and one vertex V +which is well-separated from the line, then our normal computation +should involve V otherwise the results will be garbage. + +The advantage of projecting perpendicular to the polygon normal is +that computed intersection points will be as close as possible to +their ideal locations. To get this behavior, define TRUE_PROJECT. + + +The Line Sweep +-------------- + +There are three data structures: the mesh, the event queue, and the +edge dictionary. + +The mesh is a "quad-edge" data structure which records the topology of +the current decomposition; for details see the include file "mesh.h". + +The event queue simply holds all vertices (both original and computed +ones), organized so that we can quickly extract the vertex with the +minimum x-coord (and among those, the one with the minimum y-coord). + +The edge dictionary describes the current intersection of the sweep +line with the regions of the polygon. This is just an ordering of the +edges which intersect the sweep line, sorted by their current order of +intersection. For each pair of edges, we store some information about +the monotone region between them -- these are call "active regions" +(since they are crossed by the current sweep line). + +The basic algorithm is to sweep from left to right, processing each +vertex. The processed portion of the mesh (left of the sweep line) is +a planar decomposition. As we cross each vertex, we update the mesh +and the edge dictionary, then we check any newly adjacent pairs of +edges to see if they intersect. + +A vertex can have any number of edges. Vertices with many edges can +be created as vertices are merged and intersection points are +computed. For unprocessed vertices (right of the sweep line), these +edges are in no particular order around the vertex; for processed +vertices, the topological ordering should match the geometric ordering. + +The vertex processing happens in two phases: first we process are the +left-going edges (all these edges are currently in the edge +dictionary). This involves: + + - deleting the left-going edges from the dictionary; + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - marking any terminated regions (regions which lie between two left-going + edges) as either "inside" or "outside" according to their winding number. + +When there are no left-going edges, and the event vertex is in an +"interior" region, we need to add an edge (to split the region into +monotone pieces). To do this we simply join the event vertex to the +rightmost left endpoint of the upper or lower edge of the containing +region. + +Then we process the right-going edges. This involves: + + - inserting the edges in the edge dictionary; + - computing the winding number of any newly created active regions. + We can compute this incrementally using the winding of each edge + that we cross as we walk through the dictionary. + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - checking any newly adjacent edges for intersection and/or merging. + +If there are no right-going edges, again we need to add one to split +the containing region into monotone pieces. In our case it is most +convenient to add an edge to the leftmost right endpoint of either +containing edge; however we may need to change this later (see the +code for details). + + +Invariants +---------- + +These are the most important invariants maintained during the sweep. +We define a function VertLeq(v1,v2) which defines the order in which +vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc) +which says whether e1 is below e2 at the sweep event location "loc". +This function is defined only at sweep event locations which lie +between the rightmost left endpoint of {e1,e2}, and the leftmost right +endpoint of {e1,e2}. + +Invariants for the Edge Dictionary. + + - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2) + at any valid location of the sweep event. + - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2 + share a common endpoint. + - For each e in the dictionary, e->Dst has been processed but not e->Org. + - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org) + where "event" is the current sweep line event. + - No edge e has zero length. + - No two edges have identical left and right endpoints. + +Invariants for the Mesh (the processed portion). + + - The portion of the mesh left of the sweep line is a planar graph, + ie. there is *some* way to embed it in the plane. + - No processed edge has zero length. + - No two processed vertices have identical coordinates. + - Each "inside" region is monotone, ie. can be broken into two chains + of monotonically increasing vertices according to VertLeq(v1,v2) + - a non-invariant: these chains may intersect (slightly) due to + numerical errors, but this does not affect the algorithm's operation. + +Invariants for the Sweep. + + - If a vertex has any left-going edges, then these must be in the edge + dictionary at the time the vertex is processed. + - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced + by ConnectRightVertex), then it is the only right-going edge from + its associated vertex. (This says that these edges exist only + when it is necessary.) + + +Robustness +---------- + +The key to the robustness of the algorithm is maintaining the +invariants above, especially the correct ordering of the edge +dictionary. We achieve this by: + + 1. Writing the numerical computations for maximum precision rather + than maximum speed. + + 2. Making no assumptions at all about the results of the edge + intersection calculations -- for sufficiently degenerate inputs, + the computed location is not much better than a random number. + + 3. When numerical errors violate the invariants, restore them + by making *topological* changes when necessary (ie. relinking + the mesh structure). + + +Triangulation and Grouping +-------------------------- + +We finish the line sweep before doing any triangulation. This is +because even after a monotone region is complete, there can be further +changes to its vertex data because of further vertex merging. + +After triangulating all monotone regions, we want to group the +triangles into fans and strips. We do this using a greedy approach. +The triangulation itself is not optimized to reduce the number of +primitives; we just try to get a reasonable decomposition of the +computed triangulation. diff --git a/src/kits/opengl/glu/libtess/dict-list.h b/src/kits/opengl/glu/libtess/dict-list.h new file mode 100644 index 0000000000..6ca3e1063b --- /dev/null +++ b/src/kits/opengl/glu/libtess/dict-list.h @@ -0,0 +1,107 @@ +/* +** License Applicability.

Stolfi, Primitives + * for the manipulation of general subdivisions and the computation of + * Voronoi diagrams, ACM Transactions on Graphics, 4(2):74-123, April 1985). + * For a simplified description, see the course notes for CS348a, + * "Mathematical Foundations of Computer Graphics", available at the + * Stanford bookstore (and taught during the fall quarter). + * The implementation also borrows a tiny subset of the graph-based approach + * use in Mantyla's Geometric Work Bench (see M. Mantyla, An Introduction + * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988). + * + * The fundamental data structure is the "half-edge". Two half-edges + * go together to make an edge, but they point in opposite directions. + * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym), + * its origin vertex (Org), the face on its left side (Lface), and the + * adjacent half-edges in the CCW direction around the origin vertex + * (Onext) and around the left face (Lnext). There is also a "next" + * pointer for the global edge list (see below). + * + * The notation used for mesh navigation: + * Sym = the mate of a half-edge (same edge, but opposite direction) + * Onext = edge CCW around origin vertex (keep same origin) + * Dnext = edge CCW around destination vertex (keep same dest) + * Lnext = edge CCW around left face (dest becomes new origin) + * Rnext = edge CCW around right face (origin becomes new dest) + * + * "prev" means to substitute CW for CCW in the definitions above. + * + * The mesh keeps global lists of all vertices, faces, and edges, + * stored as doubly-linked circular lists with a dummy header node. + * The mesh stores pointers to these dummy headers (vHead, fHead, eHead). + * + * The circular edge list is special; since half-edges always occur + * in pairs (e and e->Sym), each half-edge stores a pointer in only + * one direction. Starting at eHead and following the e->next pointers + * will visit each *edge* once (ie. e or e->Sym, but not both). + * e->Sym stores a pointer in the opposite direction, thus it is + * always true that e->Sym->next->Sym->next == e. + * + * Each vertex has a pointer to next and previous vertices in the + * circular list, and a pointer to a half-edge with this vertex as + * the origin (NULL if this is the dummy header). There is also a + * field "data" for client data. + * + * Each face has a pointer to the next and previous faces in the + * circular list, and a pointer to a half-edge with this face as + * the left face (NULL if this is the dummy header). There is also + * a field "data" for client data. + * + * Note that what we call a "face" is really a loop; faces may consist + * of more than one loop (ie. not simply connected), but there is no + * record of this in the data structure. The mesh may consist of + * several disconnected regions, so it may not be possible to visit + * the entire mesh by starting at a half-edge and traversing the edge + * structure. + * + * The mesh does NOT support isolated vertices; a vertex is deleted along + * with its last edge. Similarly when two faces are merged, one of the + * faces is deleted (see __gl_meshDelete below). For mesh operations, + * all face (loop) and vertex pointers must not be NULL. However, once + * mesh manipulation is finished, __gl_MeshZapFace can be used to delete + * faces of the mesh, one at a time.

The basic mesh operations are MakeEdge, + * Splice, and Delete. All the other edge operations can be implemented + * in terms of these. The other operations are provided for convenience + * and/or efficiency. + * + * When a face is split or a vertex is added, they are inserted into the + * global list *before* the existing vertex or face (ie. e->Org or e->Lface). + * This makes it easier to process all vertices or faces in the global lists + * without worrying about processing the same data twice. As a convenience, + * when a face is split, the "inside" flag is copied from the old face. + * Other internal data (v->data, v->activeRegion, f->data, f->marked, + * f->trail, e->winding) is set to zero. + * + * ********************** Basic Edge Operations ************************** + * + * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop. + * The loop (face) consists of the two new half-edges. + * + * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the + * mesh connectivity and topology. It changes the mesh so that + * eOrg->Onext <- OLD( eDst->Onext ) + * eDst->Onext <- OLD( eOrg->Onext ) + * where OLD(...) means the value before the meshSplice operation. + * + * This can have two effects on the vertex structure: + * - if eOrg->Org != eDst->Org, the two vertices are merged together + * - if eOrg->Org == eDst->Org, the origin is split into two vertices + * In both cases, eDst->Org is changed and eOrg->Org is untouched. + * + * Similarly (and independently) for the face structure, + * - if eOrg->Lface == eDst->Lface, one loop is split into two + * - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one + * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected. + * + * __gl_meshDelete( eDel ) removes the edge eDel. There are several cases: + * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop + * eDel->Lface is deleted. Otherwise, we are splitting one loop into two; + * the newly created loop will contain eDel->Dst. If the deletion of eDel + * would create isolated vertices, those are deleted as well. + * + * ********************** Other Edge Operations ************************** + * + * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that + * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex. + * eOrg and eNew will have the same left face. + * + * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew, + * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org. + * eOrg and eNew will have the same left face. + * + * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst + * to eDst->Org, and returns the corresponding half-edge eNew. + * If eOrg->Lface == eDst->Lface, this splits one loop into two, + * and the newly created loop is eNew->Lface. Otherwise, two disjoint + * loops are merged into one, and the loop eDst->Lface is destroyed. + * + * ************************ Other Operations ***************************** + * + * __gl_meshNewMesh() creates a new mesh with no edges, no vertices, + * and no loops (what we usually call a "face"). + * + * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in + * both meshes, and returns the new mesh (the old meshes are destroyed). + * + * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh. + * + * __gl_meshZapFace( fZap ) destroys a face and removes it from the + * global face list. All edges of fZap will have a NULL pointer as their + * left face. Any edges which also have a NULL pointer as their right face + * are deleted entirely (along with any isolated vertices this produces). + * An entire mesh can be deleted by zapping its faces, one at a time, + * in any order. Zapped faces cannot be used in further mesh operations! + * + * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency. + */ + +GLUhalfEdge *__gl_meshMakeEdge( GLUmesh *mesh ); +int __gl_meshSplice( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); +int __gl_meshDelete( GLUhalfEdge *eDel ); + +GLUhalfEdge *__gl_meshAddEdgeVertex( GLUhalfEdge *eOrg ); +GLUhalfEdge *__gl_meshSplitEdge( GLUhalfEdge *eOrg ); +GLUhalfEdge *__gl_meshConnect( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); + +GLUmesh *__gl_meshNewMesh( void ); +GLUmesh *__gl_meshUnion( GLUmesh *mesh1, GLUmesh *mesh2 ); +void __gl_meshDeleteMesh( GLUmesh *mesh ); +void __gl_meshZapFace( GLUface *fZap ); + +#ifdef NDEBUG +#define __gl_meshCheckMesh( mesh ) +#else +void __gl_meshCheckMesh( GLUmesh *mesh ); +#endif + +#endif diff --git a/src/kits/opengl/glu/libtess/normal.c b/src/kits/opengl/glu/libtess/normal.c new file mode 100644 index 0000000000..f69544618c --- /dev/null +++ b/src/kits/opengl/glu/libtess/normal.c @@ -0,0 +1,258 @@ +/* +** License Applicability.
