SW and comical sketching (part 3)

Question asked by Philippe Carette on Jun 28, 2011

When a curve is tangent to another, I learned, when I was younger, that there are 2 possibilities for such tangent : a curve has 2 possible orientations, in a 3D affine space.

 

 

But SW designers haven't learn such basic concept.

 

So a relation of tangency give one choice, and get by with that....

I suggest that you spend your money with professional developments.

 

This begins with correct basic concepts with the affine geometry in affine spaces of dimension 3.
