I try to set fields in `btIndexMesh` in order to use geometry that I've read from OBJ file using `tinyObjLoader` lib.
I'm creating the btIndexMesh in a following way.
Code: Select all
btIndexedMesh indexed_mesh = btIndexedMesh(); indexed_mesh.m_numTriangles = vertex_count / 3; indexed_mesh.m_triangleIndexBase = (const unsigned char*) &shapes[s].mesh.indices.vertex_index; indexed_mesh.m_triangleIndexStride = 3 * sizeof(tinyobj::index_t); indexed_mesh.m_numVertices = vertex_count; indexed_mesh.m_vertexBase = (const unsigned char*) &(attrib.vertices); indexed_mesh.m_vertexStride = 3 * sizeof(float);
As for atrrib and mesh.indices goes:
- shapes.mesh.indices is of type std::vector<tinyobj::index_t> and contains indices of vertices that form triangles (a map from to attrib).
- attrib.vertices is of type std::vector<float>) and contains all the coordintes of vertices
Here you have the code of the OBJ loader (it's also used in bullet examples).

So, the code doesn't seem to be right, because I get differnt mesh than using using btTriangleMesh class.
Can some tell me what I'm doing wrong?
