Mykolas 0 Posted March 14, 2017 Hi fellows Houdinistas. I want to dissolve random edges on triangulated surface with even edge lengths. If I try to use a sort node to randomize + group node to create edge group there - it creates edge group with random polygons edges (all connected edges on one triangle) selected. Is there a way to select some random (not connected to each other) edges? Any way to access edge group in VEX? Houdini 15.5 here. Thanks. Mikas Share this post Link to post Share on other sites
f1480187 739 Posted March 14, 2017 Easy with Convert Line node. Every edge then will have unique primitive, grouping is trivial. After that, copy edge group to original geometry. random_edges.hipnc Share this post Link to post Share on other sites
reeson 1 Posted January 10, 2019 Can you do this, lets say, on a single primitive of a torus (that you split with polysplit), but instead shifting the random edge selection with time, you use for each loop. Share this post Link to post Share on other sites
reeson 1 Posted January 10, 2019 (edited) I'm attaching my hip file. How can I have a different sort seed per each primitive in this for-each loop. Cheers! procedural subdivide11.hip Edited January 10, 2019 by reeson Share this post Link to post Share on other sites
Noobini 655 Posted January 10, 2019 here, I've randomized your sort and also offset in random edges selection...you can see purple lines going to both places where it's being used vu_procedural subdivide11.hiplc 1 Share this post Link to post Share on other sites
