-General Polygon Tesselation
----------------------------
-
- This note describes a tesselator for polygons consisting of one or
- more closed contours. 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)

-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.

-/* The mesh structure is similar in spirit, notation, and operations
- * to the "quad-edge" structure (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 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. All external faces can be "zapped"
- * before the mesh is returned to the client; then a NULL face indicates
- * a region which is not part of the output polygon.

- *
- * ********************** 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.

- * is always to the left of all vertices in the concave chain.
