renderfan Posted October 27, 2011 Share Posted October 27, 2011 Hi! How can i group intersecting polygons like in picture? Is it possible with Partition-Sop? Thank you !! Quote Link to comment Share on other sites More sharing options...
ehsan parizi Posted October 27, 2011 Share Posted October 27, 2011 (edited) How about defining a primitive attribute, give it a default value of 1, and use a attribtransfer sop and group based on where that attribute is >1. EDIT : nope! that wouldn't work in this case Edited October 27, 2011 by ehsan parizi Quote Link to comment Share on other sites More sharing options...
ehsan parizi Posted October 27, 2011 Share Posted October 27, 2011 ok, here's a file that kinda does the same thing you want, it's not the best way to do that, and could get really slow when you have complicated geometry. + you need some more nodes to make it work perfectly if your copied geo has more than 1 primitive. btw, if someone has a better and simple solution , please share. group_overlap.hipnc Quote Link to comment Share on other sites More sharing options...
tmdag Posted October 28, 2011 Share Posted October 28, 2011 it depends on your desired criteria of grouping..For eg. you could group them by distance Quote Link to comment Share on other sites More sharing options...
