Temporally Stable Oriented Bounding Box (OBB) [Extract Transform SOP] (Patreon)

Before I posted an example of this using the Rigid Transform SOP. The same result can now be obtained using the Extract Transform SOP in Houdini 18.5, which now supports the extraction of non-uniform scales.

It's useful to know how to do this using the standard operators. Many studios restrict the use of external tools so you might find yourself in this situation.

In the gif the outer bbox is from the Extract Transform SOP. As you can see both operators perfectly match.
