Processing Coding Questions

Hi All,

I would like to do the sacn line algorithm in Processing. I have read a lot about it but I have no clue how to start it. Do you have any example or something what helps to start to implement it?

Thanks a lot in advance!

Ok, I’ve seen it and I understand how this should work.

What I dont know, how can I store the coordinates of the points where the scan-line goes through the polygon.
