BlackPariah Posted July 30, 2018 Share Posted July 30, 2018 Hello! I fed a simple grid to a voronoi fracture node (fracture points and geometry source both from the same grid object) & it made some pieces. Great! How can I group the pieces in order to use it for a followup extrude node? I want to extrude and slightly inset the pieces... like a brick pavement or stone wall type of operation...

Noobini Posted July 30, 2018 Share Posted July 30, 2018 in the voronoi, Cut tab, enter a small value in Cut Plane Offset.. then just apply an extrude after.. 1 Quote Link to comment Share on other sites More sharing options...
BlackPariah Posted July 30, 2018 Author Share Posted July 30, 2018 (edited) The inset on the polyextrude node doesn't work properly with the Cut Plane Offset... clustering doesn't work either. I had it working yesterday but I forgot what I did in the process of trying many other things... not sure if I added a connectivity node or partition or a group node... & now I can't remember lol Edited July 30, 2018 by BlackPariah extra info Quote Link to comment Share on other sites More sharing options...
BlackPariah Posted July 30, 2018 Author Share Posted July 30, 2018 I think I used a for each loop to extrude each voronoi piece... was a late night lol... Quote Link to comment Share on other sites More sharing options...
midicon Posted July 31, 2018 Share Posted July 31, 2018 With a connectivity sop you can separate each piece with a attribute called class you can extrude/bevel, with this. 1 Quote Link to comment Share on other sites More sharing options...
BlackPariah Posted July 31, 2018 Author Share Posted July 31, 2018 I tried with connectivity & still keep getting weird artifacts... but I think I figured out the source of the problem... it's the voronoi node itself. It's outputting overlapping primitives with normals facing up/down randomly... so that's why it won't extrude properly. The thing is I'm using the same grid object as the fracture geometry and voronoi points... not sure if this is causing the problem... maybe I need some kind of cleanup node like a fuse or polydoctor... idk, it was working 2 days ago and now I can't figure it out...

vicvvsh Posted July 31, 2018 Share Posted July 31, 2018 (edited) Hi Jack, take a look at hip in attachment. Is this what you want to achieve? voronoi_extude.hipnc Edited July 31, 2018 by vicvvsh 1 Quote Link to comment Share on other sites More sharing options...
BlackPariah Posted July 31, 2018 Author Share Posted July 31, 2018 YES! Exactly this! I was missing the divide and facet nodes... And now I recall where I had seen the voronoi pattern examples... http://www.tokeru.com/cgwiki/?title=Houdini#Voronoi_cluster_and_fracture In case anyone runs into this problem, that example has some nice setups for quick patterns. Thank you guys Quote Link to comment Share on other sites More sharing options...
