How do object transforms work in Rhino? Usually in 3D programs each object has a local transformation matrix, so they can be stacked in a hierarchy, and the underlying geometry doesn’t need to be touched when simply transforming objects around in the scene.
I think this is also how Rhino works, because when you query underlying geometry it looks like it’s expressed in local space. But I cannot figure out how to get that matrix.
How do I access a scene object’s transformation matrix?
