- README for Dual
- ---------------
- Dual is a simple application to demonstrate the concept of duality as
- used in computational geometry (and arrangements). Dual shows the
- primal and dual planes for the mapping (a,b) <=> y=ax-b; it allows you
- enter (and delete) points and lines in either plane to construct an arbitrarily
- complex arrangement. Points and lines may be colored and labeled, and
- changed dynamically.
