My problem is quite hard to explain, I have had a few goes at putting this across before but this should make it clear…
I want to be able to cut several holes out of a shape (ideally using the GLU tessellator) to make one big hole. I run into problems when the shapes (contours) overlap (I end up with islands).
I have uploaded a simple graphical example of what I am trying to do here: http://www.jbcode.com/problems/MultipleTessellation/
I expect that the best way around this would be to cut each shape out a time by feeding resulting data back into another tessellator.
What I want to establish is:
- Is this possible?
- Is this the best way to solve my problem?
- How would I go about doing it?
Any help here would be greatly appreciated.
