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):
