jumper Posted February 11, 2011 Share Posted February 11, 2011 Hey, I am trying to use point clouds to cut 'pockets' in a volume density - I have set it up in a vopsop which looks at the pscale of points using pcopen and pcfilter. This kind of works and holes are eaten into the volume density. The only problem is pscale doesn't affect the SIZE of the holes...only the the amplitude of the density. The size of the holes is determined by the radius value on pcopen.It would be nice if the holes were different sizes based on pscale (I am trying to create bubbles in foam). Any help would be much appreciated. cheers! Stephen pointCloud_v002.hip Quote Link to comment Share on other sites More sharing options...

Stephen i think the easiest way to do this is to use pciterate rather than ptfilter. that way you can be more specific about how you create the holes. in the attached example, i'm making a coordinate system for each point (that includes the scale) and just looking at the distance from the origin of that coordinate system to make the holes. this way changing the radius of your pcopen doesn't affect the result.
