Recast fails on large levels because of 16-bit indices #106

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On very large terrain levels, Recast will fail because of polygon/vertex counts 
over 0xFFFF.

Fixed in 221.

There are several indices which are stored in 16 bits because 99% of the cases 
that is more than enough. The max number of vertices and indices in a navmesh 
tile is 65535. This will not change.

The detail mesh can contain much more triangles than that, so 16 bit index for 
detail meshes was not sufficient. I changed the code so that detail mesh can 
carry all the necessary detail triangles for the maximum number of polygons.
