To add to this, I am interested in creating geometries containing thousands of points. For example, chirped & apodized spiral Bragg grating waveguides. Presently we do calculations in Matlab, save the coordinates to a file, and import them into the layout tool. Not very efficient.
It would be nice to have a PCell with calculations efficiently done in Python.
in general you don't need to recompile KLayout. But you may need to recompile numpy.
Here is what I know:
any other Windows problems? the recursive shape one, probably?
