vbk!!! Posted July 13, 2011 Share Posted July 13, 2011 Hello, I am trying to paint a mesh with a point cloud ( it's not a shading test) I am trying to iterate trough a point cloud to displace a mesh. The point cloud is create with particles. But with the VOPSOP I created, a lot of artefact appear. Way to much ... I attached my .hip file if you want to check. I don't understand at all what's wrong. Thanks for your help. pcloudtest.hip 1 Quote Link to comment Share on other sites More sharing options...

tjeeds Posted July 14, 2011 Share Posted July 14, 2011 Here is the correct setup for a point cloud loop in VOPs (as originally provided by Andrew Clinton). Also I threw a pcfilter alternative in there but for some reason it's grabbing the origin in addition to the point cloud, anyone know why? pcloudtest1.hip Quote Link to comment Share on other sites More sharing options...
Div Posted July 14, 2011 Share Posted July 14, 2011 Didn't have a look to your file, but I guess that is because points cloud vops will return P=(0,0,0) if there is no point found within the radius, so if you're using P (ex. for a distance) you will grab the origin. To fix that you have to check if the length of P is 0 and then process your data accordingly. Hope that make sense Quote Link to comment Share on other sites More sharing options...
