Very cool indeed. I'm especially interested in the memory requirements so far, really promising! When attempting this in Mantra I ended up having to use a Google Cloud instance that had +130GB of RAM to be renderable all at once. (This was using a heavily nested packed primitive workflow.)

Definitely RFE worthy. I would love a more formal CVEX Geometry Shader that would allow manipulation of geometry objects. Internally we did exactly this and the lighters use it to do last minute tweaks to geometry they get from the FX dept. Saves from having to destroy the filers from another intermediate cache.

So ya, RFE away!

If your geometry is just points or curves you can use either the Point or Curve Engine Procedural to do this without eating up a license, basically allowing you to run a SOP network on geometry.

Houdini's Fur system uses this approach actually if you want a robust example.

A simple example is attached. Just render a few different frames to see the geo move.
