3. As a first step I tryied to understand and find one module of roof, using the math approach. So, with the hepl of Grath Mapper, the sequence of points repeat the form of Caussian curve.
4. Defects in the geometry: now it seems complicated to control z coordinate of each point in the sequence
5. Probably, in the next steps I can work on the curvature of the curve, and then create the surface
