It's only used to detect if the segment is parallel to the polygon edge in question, and if so, skip actually doing the intersection test. This sets the epsilon to 1e-6, which is about 10x the machine epsilon for 32bit floats, so it's low enough to not give false positives but it's large enough to correctly detect segments and polygon edges that are very nearly parallel.
* Make dtClosestHeightPointTriangle use no epsilon (except for checking
denominator)
* When point is outside poly, directly find closest height from boundary
detail edges instead of first interpolating and then finding height from
detail tris.
* When point is inside poly, if all dtClosestHeightPointTriangle queries
failed, then find height from detail edges. This should only happen if
the point is right on top of an internal detail tri edge.
Documented DetourAlloc.h and most members in DetourCommon.h.
Added warning related to issue 180. (Limitation on use of dtNavmeshQuery::findNearestPoly.)
Standardized the use of tab/space indenting in the API documentation.
- Added detail height mesh generation (RecastDetailMesh.cpp) for single,tiled statmeshes as well as tilemesh.
- Added feature to contour tracing which detects extra vertices along tile edges which should be removed later.
- Changed the tiled stat mesh preprocess, so that it first generated polymeshes per tile and finally combines them.
- Fixed bug in the GUI code where invisible buttons could be pressed.
