It's not about just making chunks of points from the cloud. I think one way to do this is to get normals and collect approximately equal normals under one set and call this a small surface. WebWhen I run your code, after changing setRadiusSearch(15) to setKSearch(15), the code run without any problem.I don't think that line caused the problem though.
