Atom Posted August 22, 2017 Share Posted August 22, 2017 (edited) I was working on a scene where I wanted lines to wrap around a geo shape but lie upon the surface. FindShortestPath is used. Here is a basic setup with UV mapping setup, thanks to Matt Estela, as well. Currently it is setup in lightning mode where the lines change per frame. This is accomplished by adding $F to the random seed of the scatter. To make the lines stand still simply remove that expression. ap_connect_points_around_geo_surface.hiplc Edited August 24, 2017 by Atom 2 Quote Link to comment Share on other sites More sharing options...
vinyvince Posted October 9, 2017 Share Posted October 9, 2017 Interesting , thanks for sharing. Is there a way to for very complyx scene to generate a cloud mesh approximation of the all scene and use this as your surface? Sorry, new to Houdini and mosly on the creative artistic side myself... Cheers Quote Link to comment Share on other sites More sharing options...
Jordan Walsh Posted October 17, 2017 Share Posted October 17, 2017 Best way is to use VDB from Polys and use the surface SDF to find your surface location. the sdf will give you the distance to surface and you can use volume gradient to find the direction to surface. Works only on closed geo though... so get that poly cap working! Quote Link to comment Share on other sites More sharing options...
vinyvince Posted October 22, 2017 Share Posted October 22, 2017 Thanks Jordan Good suggestion, now in my case and a imagine a lots of others scenario that would be a serious limitation Quote Link to comment Share on other sites More sharing options...
