Method	Description
AddWinding ( LibTessDotNet.MeshUtils.Edge eDst, LibTessDotNet.MeshUtils.Edge eSrc ) : void
EdgeEval ( LibTessDotNet.MeshUtils.Vertex u, LibTessDotNet.MeshUtils.Vertex v, LibTessDotNet.MeshUtils.Vertex w ) : Real	Given three vertices u,v,w such that VertLeq(u,v) && VertLeq(v,w), evaluates the t-coord of the edge uw at the s-coord of the vertex v. Returns v->t - (uw)(v->s), ie. the signed distance from uw to v. If uw is vertical (and thus passes thru v), the result is zero. The calculation is extremely accurate and stable, even when v is very close to u or w. In particular if we set v->t = 0 and let r be the negated result (this evaluates (uw)(v->s)), then r is guaranteed to satisfy MIN(u->t,w->t) <= r <= MAX(u->t,w->t).
EdgeGoesLeft ( LibTessDotNet.MeshUtils.Edge e ) : bool
EdgeGoesRight ( LibTessDotNet.MeshUtils.Edge e ) : bool
EdgeIntersect ( LibTessDotNet.MeshUtils.Vertex o1, LibTessDotNet.MeshUtils.Vertex d1, LibTessDotNet.MeshUtils.Vertex o2, LibTessDotNet.MeshUtils.Vertex d2, LibTessDotNet.MeshUtils.Vertex v ) : void	Given edges (o1,d1) and (o2,d2), compute their point of intersection. The computed point is guaranteed to lie in the intersection of the bounding rectangles defined by each edge.
EdgeSign ( LibTessDotNet.MeshUtils.Vertex u, LibTessDotNet.MeshUtils.Vertex v, LibTessDotNet.MeshUtils.Vertex w ) : Real	Returns a number whose sign matches EdgeEval(u,v,w) but which is cheaper to evaluate. Returns > 0, == 0 , or < 0 as v is above, on, or below the edge uw.
Interpolate ( Real a, Real x, Real b, Real y ) : Real
IsWindingInside ( WindingRule rule, int n ) : bool
