Is there any way to get calculated tangent and bitangent for normal mapping?

No description provided.

There is no built-in way to do this right now.

On the one hand, something like this would not really fit into the library conceptually, because the OBJ file format does not have the concept of tangents or bitangents.

On the other hand, it would be a very reasonable and useful extension for the goal to provide the geometry data of OBJ in a renderable form. (This would go hand in hand with a utility method to compute the normals (if they are not contained in the OBJ file)).

I'll definitely consider this, but cannot make any promises yet.

Thanks. It would be great if you include this in it.
