do you mean a test to see if two line segments intersect?

This looks reasonable:


It probably makes sense to translate to Cython (or use the C and call with

I"ve also got similar code in a little package of mine:


Already Cython, and includes code to check a whole bunch at once, stored in
numpy arrays:


I hope it's useful to you.
