[comp.graphics] looking for polygon intersection routines

kyle@aplvax.UUCP (Kyle Upton) (12/24/87)

Does anyone know of public domain C language code for testing whether
non-convex 2-D polygons intersect?
This is the only requirement I have at this time, but information
or code to perform general polygon set-operations is also welcome.
Thanks in advance.
