Copy 3D geometry from mesh to OpenGL video memory. Proper vertex array object(VAO) and vertex buffer object(VBO) should be bound before calling this function.

size_t MeshToVertexBuffer(// Return triangle count 
        standard::windows::opengl::IOpenGL *graphics, // Native graphics interface 
        const Mesh &mesh, // Mesh with 3D geometry 
        bool use_vertex_normal); // Whether copy individual vertex normals or use polygon ones
