[ODE] dGeomTriMeshDataBuildSimple and dGeomTriMeshDataBuildSingle

[Duncan Frostick]

Do trimeshes in ODE have to be contiguous? The mesh I'm trying to add is 
a block of 3D text with spaces between each character, and I've not had 
this trouble with simple contiguous meshes that I've tried using.

Cheers, Duncan

nothing to do with my pointers (after I'd fixed them). I was 
overstepping the bounds of the vertex buffer because I hadn't cloned the 
mesh into a new mesh with smaller FVF that only contained XYZ 
components. Once I had done, and used the cloned mesh, it was fine.

dGeomTriMeshDataBuildSimple in the same way as in the test code but I'm 
getting a crash when I try to do so. Exactly the same appears to happen 
with dGeomTriMeshDataBuildSingle when I try using that instead. When the 
crash started, it produced a "Debug Assertion Failure in dbgdel.cpp 
Line: 52"... whatever that is. But after googling I changed the runtime 
library used for code generation to it's multithreaded version and that 
stopped the debug assertion error, now it just crashes out upon calling 
dGeomTriMeshDataBuildSimple or Single.

dGeomTriMeshDataBuildSimple and fixed it?
