ZenGL

[Andru]

I'm just curious: but could I use some of your audio and font code in Prometheus? (along with the editor?).

You can use it while all modified ZenGL units(or units, that use ZenGL code) have copyrights. But audio... I think it won't be easy to port without using a lot of ZenGL units, but you can try to do this

So, ZenGL got an official website - zengl.org. In few days I will try to complete it, but my designer skills... never mind

Seems I catched known bug for GeForce FX videocards, that was released when FBO wasn't a standard... In my compiled demo I have removed one line of code(attaching depth buffer to FBO). So, maybe I will disable FBO for GeForce FX and switch to PBuffer, or I will try to make some "magic" with MipMaps(like described here), or... just disable depth buffer because ZenGL for now is 2D only

WILL
Thanks a lot
