There is no ray object in Shapely. You could approximate one in the context of a given geometric object target like this:
1. Determine the bounds of the target (target.bounds) 2. Using your ray origin and angle, find a point along the angle that is on the other side of the target bounds from the origin 3. Combine that with the origin to make a line Of course, if the origin is within the target you will have to extend the line in both directions.
