/*!

\param trimesh An uninitialized GIM_TRIMESH  structure
\param vertex_array A buffer to a vec3f array
\param vertex_count
\param triindex_array
\param index_count
\param copy_vertices If 1, it copies the source vertices in another buffer. Else (0) it constructs a reference to the data.
\param copy_indices If 1, it copies the source vertices in another buffer. Else (0) it constructs a reference to the data.
\param transformed_reply If , then the m_transformed_vertices is a reply of the source vertices. Else it just be a reference to the original array.
