Hi group,

I did computation on linear programming.

I would like to find the solution for N = 3 (three variables, 3D space) by a
cool graphical analogy. Everybody is probably aware of the method:
machete-cutting space, where you get a polyhedron out of it (the boundary
faces are the constrains on variables).

I can't implement the thinking into Mathematica. I have a cube and would
like to slice it apart by some inequalities (space division) and equalities
(surface filing).

Something like Boolean function in 3D Studio Max where you produce solids...
but 3DSMax isn't that math-oriented.

Do you have any clue / idea for me?

Thank you,
