rcTriangleMesh Enhancement about recastnavigation HOT 3 OPEN

I'd suggest adding this class as a helper, which maintains the verts/indices buffers with some nice methods like AddTriangle above, but keeping the existing Recast functions the way they are now, and exposing e.g. const float* getVertices() const from this new class. There's no need to complicate the Recast API; this could exist completely separately with no dependency on it from Recast.

I'm a big fan of helper classes as well. It would particularly be useful if it eventually provided accelerated spatial queries for getting relevant triangles for a tile bounds for instance.

I did something similar. For what it's worth I found it helpful in my case to have 1 tri mesh gather object per navigation mesh tile. When I had it process geometry (3d models etc) it would prune triangles not touching that tile (+ border). This made the generation of a tile very efficient with only triangles that impact it's generation analyzed, and memory for the triangles in each tile localized for better cache hits in multithreaded generation.
