magneto Posted February 14, 2012 Share Posted February 14, 2012 I am currently using pointdist in a Group SOP to find the closest prims to a point that a specify which is animated over a high-res mesh, but it seems slow on moderately high-res mesh. Are there alternative ways to do these kinds of things? Thanks Quote Link to comment Share on other sites More sharing options...
Macha Posted February 15, 2012 Share Posted February 15, 2012 Pointclouds? One point per prim, or many points per prim with an attribute telling you the prim. Quote Link to comment Share on other sites More sharing options...
magneto Posted February 15, 2012 Author Share Posted February 15, 2012 Thanks Macha, I never used point clouds, but can you look up prims using them? Or do you have to say find all the points that share the same prim to find the closest prim? pointdist allows you to specify 3 as the last parameter to return the closest prim.

Macha Posted February 15, 2012 Share Posted February 15, 2012 You can't use prims directly but you could choose points representing prims if that's accurate enough. 1 Quote Link to comment Share on other sites More sharing options...
