extraction can be restricted to a mesh and within the mesh to a primitive by specifying the corresponsing indices as parameters to this function. The number of meshes can be extracted from the gltf document via doc.meshes.size() and the number of primitives for a given mesh with doc.meshes[mesh_index].primitives.size().
