algorithm
Hello, I have map (openstreetmap project) with many buildings. Each building is a polygon. How can I make saddle roof parts polygons for every building outline?
Algorithm should transform one polygon in 2D to set of polygons in 2D (or 3D).
Reason for this transformation is visualization - better rendering isometric view.
For example (shading isn't important):

Thanks
