Why is transforming a shapely polygon not working in some cases?
Webb27 mars 2014 · 1 Answer. Sorted by: 2. As a preprocessing step you can calculate for each edge, which side of the edge determines the outside of the polygon. This is much cheaper than O (n) time for every intersection point. Then when two edges intersect, you can determine which two line segments are outside and which two are inside.
