Hi,


What I'm looking for is similar to Nuke's O-flow tool (where a 2d grid of motion vectors are generated for an image sequence, based on image information).

I wonder if similar could be possible using existing Houdini tools (microsolvers?) for volumes? Say, I have a sequence of 3d volumes (scalar/density), and I'd like to generate a motion vector volume for them, by analyzing the difference between the volume on the current and the next frame.

I hope I'm making sense here…

cheers,
