Overload Posted July 22, 2009 Share Posted July 22, 2009 Is there a way to smooth a point attribute inside VOPS? I can do this with the smooth node, buts way to slow for the amount of geometry I'm applying my attributes too. I need a smooth fall off of noise that is getting applied. Thanks!

Anthony Point cloud methods will smooth (average) any attribute you want on a geometry, and are very fast. Quote Link to comment Share on other sites More sharing options...
Overload Posted July 22, 2009 Author Share Posted July 22, 2009 Could you elaborate? I see all the point cloud nodes, not too sure what to do with them. Quote Link to comment Share on other sites More sharing options...
brianburke Posted July 22, 2009 Share Posted July 22, 2009 Hi Overload. The basic workflow for the point cloud functions is: Open some geometry as a point cloud, queue up some points (how many is determined by the Number of Points parameter and the Search Radius parameter), process these points in some way, return the result. The pointcloudfilter() processes the points doing a weighted average, which works well for smoothing. I attatched a very simple file showing this workflow. pointcloudsmoot.hip You should prefilter your noise if at all possible tho, that way you can apply a smooth noise in the first place and avoid having to do expensive smoothing operations.

Overload Posted July 22, 2009 Author Share Posted July 22, 2009 Sweet, thanks I'll give this a try. Looks like it should work for what I'm after. Quote Link to comment Share on other sites More sharing options...
