Generate a parallel surface.
Generates an offset surface from this surface. An offset surface is a surface wich has its surface parallel to an other one. There is a distance of d between the two parallel surfaces.
The algorithm used is very naive. It generates a surface such that a point s_2(u,v) = s(u,v) + d n(u,v) where s_2(u,v,) is the point on the parallel surface at (u,v) , s(u,v) is the point on the original surface at (u,v), d is the offset between the two and n(u,v) is the normal on the surface at the point (u,v).
