=46rom what I've found, dGeomTriMeshDataBuildSingle1 should only be used
with single precision numbers and dGeomTriMeshDataBuildDouble1 with
doubles. TriMeshData.build was using BuildSingle1 even if ODE was built
with double precision dReals resulting in incorrect vertex data. I've
fixed this in CVS by replacing the call to dGeomTriMeshDataBuildSingle1
with one to dGeomTriMeshDataBuildSimple.

Furthermore, it seems that these functions take the number of
indices--not the number faces as was being passed before. This could
explain why ODE was ignoring some of the triangles.
