eko posted a topic in HDK : Houdini Development KitHi, I have a question! Is there a function about the K-Nearest Neighbor algorithm in HDK. I just find the "findAllCloseIdx(pt,maxdist,list)".It works fine. But I wonder if there is a function like ”pcopen()“ in vex. “findAllCloseIdx" has a "maxdist" option. I also need the "maxpoints" limit to make it more faster.Please help me! Thanks!
