[Sidefx-houdini-list] getting a local space for a transforming object

Do you work in a large pipeline where you occasionally need to remodel an
animating (transforming - not deforming) cache in some non-transforming
local space? Imagine if there was a SOP that could put any moving object on
the origin and align it with some cardinal axis - and which stored the
original space for later repositioning? It's easy enough to put an object on
the origin - but how do you align it to an axis or get it upright?

With a SOP based on this paper we could perform all manner of modeling
operations on a previously moving shapes as they sit on the origin not
moving, and then afterwards use an extracted centroid with N and up vectors
with a copy SOP to put the modified model back in it's original animating
space.

How handy would that be!?! Any takers for an RFE?

Cheers
