About ...holes

[Paulus]

Suppose that we have a general surface -let's say made up with quads.
I want to create a "hole" on the surface .Should I redesign the surface or do sth with blending? http://www.opengl.org/discussion_boards/ubb/frown.gif

[Korval]

Redesign the surface.

Is there no 'simpleish' way of doing boolean operations in GL, never really thought about it before.
