I want to perform a convolution between two sets of points, and I was thinking python would be a good way to do this… any ideas of how I can send the point positions into a python script/expression?

btw, is there perhaps an easy way to do this in CHOPS? (just a side question

or perhaps, to simplify the question, whats the best way to iterate through a set of points in a houdini scene within a python expression?
