Fabiano Berlim Posted December 4, 2013 Share Posted December 4, 2013 Given a position and ray vector direction, is there any vop shop node (or vex function) that tells me how many surfaces the ray intersects? Quote Link to comment Share on other sites More sharing options...
Jason Posted December 4, 2013 Share Posted December 4, 2013 Does this help? Wednesday, August 21, 2013 Houdini 13.0.152: The VEX trace() and gather() functions may now return array values as output. Array outputs will store an entry for each hit that was composited during ray tracing. Add a new "all" samplefilter to allow all hits to be traversed regardless of whether they are hidden. http://www.sidefx.com/docs/houdini13.0/vex/functions/trace There wouldn't be a VOP for it, besides the InlineCode VOP Quote Link to comment Share on other sites More sharing options...
