jujoje Posted June 10, 2014 Share Posted June 10, 2014 Hi all, I was wondering if anyone had given the vdb advect points a shot? I’m trying to move some points along an sdf and am not having much success either with Projection or Constrained Advection. I’ve attatched a .hip file, but in terms of results what I'm getting: Advection: Works fine Projection: Doesn’t appear to do anything Constrained Advection: Crashes Houdini Has anyone else had any luck with this node? I’m not sure whether it's just I’ve set it up wrong, or giving it the wrong input... Cheers, Julian vdb_advect_pt.hip Quote Link to comment Share on other sites More sharing options...
csmnt Posted June 10, 2014 Share Posted June 10, 2014 If I recall correctly there is an example for that node included in the Houdini example scenes over at openvdb.org: http://www.openvdb.org/download/houdini_examples.hip.zip 2 Quote Link to comment Share on other sites More sharing options...
jujoje Posted June 11, 2014 Author Share Posted June 11, 2014 Hey csmnt, thanks for that file; really useful overview of vdbs in Houdini It looks like I was missing something straightforward; you need to attach a vdb analysis node and set it to closes point before connecting it to the closest point input. Attached the fixed hip in case anyone is interested vdb_advect_pt_fixed.hip 4 Quote Link to comment Share on other sites More sharing options...
