1  Java Game APIs & Engines / JOGL Development / Re: Cylindrical hole in a cuboid? on: 2011-11-20 16:59:45
Thanks theagentd, finally I've been successful. I generated the geometry, both for the circles on either side of the block and the inside walls of the hole. Took me quite a bit of work, especially calculating the normals.

Using the stencil buffer would make everything in that area black (or another color), right? I would like to see the inner side of the hole, so it seems to me the only solution is generating the geometry. Quite a bit of work for such a simple effect...
3  Java Game APIs & Engines / JOGL Development / Cylindrical hole in a cuboid? on: 2011-11-18 18:41:24
Hi all,
I've experimented a bit with JOGL 1.0, now I would like to take it a step further. A simple question, but I found no answer on the internet:
How would I bore a cylindrical hole into a cuboid? I've tried intersecting a cylinder with a solid box, but then of course the cylinder is invisible because it doesn't create a hole. I was successful in creating a square-shaped hole using tessellation (glu.gluTessVertex()), but that's easy because there are only 4 vertices on either side of the box. I'm missing a method like glu.gluTessCircle()... Probably I need a deeper understanding of the API here, anyway I would very much appreciate if someone could give me a hint. Thanks!
