[ODE] Trimesh collision problem

thanks for your help, but it still doesnt work. Maybe thats because I use
ODE 0.7 binary release?
Btw neither in the WIKI nor in the official docu I found
dGeomTriMeshDataBuildSingle or %Single1 - where did ya find them?
An other question: vertexpoints should be 4*dReal, how can you pass a
pointer to your HsVector array? HsVector is a struct of 3 floats as you said
- not 4 floats,

Actually no, I think I've spotted the problem -
dGeomTriMeshDataBuildSimple takes dVertex data which is actually an
array of quad-floats, rather than three.
If you see what dGeomTriMeshDataBuildSimple resolves to, it'll make more
Vertices, 4 * sizeof(dReal), VertexCount,
Indices, IndexCount, 3 * sizeof(unsigned
dGeomTriMeshDataBuildSingle( g, p_vertex_data, sizeof( HsVector ),
vertex_count, p_index_data, triangle_count * 3, sizeof(
UINT32 ) * 3 );
Where HsVector is a struct of 3 floats
Hope that helps!
