Source: http://people.freenet.de/ki_onyx/Tesselator.zip (80kb)

7zipped class files are about 40kb... it's ok I guess Wink

As far as I can tell it works. However it would be nice if someone who knows what he's doing (e.g. not me) takes a look. Some refactoring might be a good idea.

Oh and I'd to guess at one place:
public static final float GLU_TESS_MAX_COORD = 1.0e15f;
(GLU_OVERRIDE.java)

In the root dir of the zip file is a little demo, called "Tess.java". I hadn't adjusted the projection stuff, but both thingies are visible.

Good work.
I never used glu tesselation stuff myself, so I don't know how well it works. So I just take your word for it :-)
The source looks okay to me.

The code that's in Jogl is a port to Java I made of the SGI reference implementation. It's essentially identical to the SGI implementation except that I disabled an optimized code path that generated incorrect results for one of the tesselator examples in the red book. I didn't put any time in actually figuring out how the algorithm itself works, but you should be able to piece it together from the comments in the code.

>optimized code path

Hehe... well, right now it's a single on-level-load operation and I don't really care if it takes 50msec or 200 Wink

>I didn't put any time in actually figuring out how the algorithm itself works

Neither do I (and I mean the whole thing). Slapped it together in ~3h (there is no way that I could understand ~230kb source in that timespan).

Oh and since you are here. Thanks for your effort Smiley
