houdini PositionToPoints from aov


Recommended Posts

Hi,

 

  currently I am using Nuke to create a point cloud from a world position pass / P pass, and after that exporting the alembic to houdini to create a mesh from the point cloud.  I would like to avoid using nuke, and rebuild the data directly in houdini.  I know it must be easy peezy but really have no idea how to do it after a lot of reading.

 

  How can I recreate Nuke's PositionToPoints node in houdini, so I can rebuild the point cloud from the P aov of my exr, hopefully by combining multiple frames.  Thank you!!

you should be able to just use

dense grid (you can switch to only points if you want) -> uv texture  -> attrib from map (pick your image, Texture Channel: P (or whatever your AOV is called), Export Attribute: P)
