When you have sphere, for example, its controur is circle.
Normal vector to this circle is the same as projected normal
vector to sphere in this point. Thus we have direction of
sphere's controur in this point and we can search next point
in nearly that direction. This fails for edges on rotated cube,
for example (generally on all edges, it is usable for countour
of objects).

And it fails also on edge between two parts of some CSG.
