For a shader I need to convert the global coords sd->vd->p to local object coordinates. To get the object matrix, I have to acquire the object.

So my question is:

How to get that object?

Any help and insight is appreciated!

PS: Of course, vd might be NIL, but that case is already dealed with...

Couldn't you use the Matrix of the RayObject of the BaseVolumeData class?
