Hi, I''m now programming OpenGL, but 3dfx card owners can run my programm accelerated ? If it is, what drivers can do that ???

Why shouldn''t they be able to do that? They can run Q3A which uses OpenGL, unlike Q2 that used a miniGL.

As far as the card has opengl drivers, your application will work.
3Dfx voodoo? all have an OpenGL drivers, the fact that it''s a miniGL driver or an ICD OpenGL drivers won''t change anything.
The ICD is required to use apps such as 3DS and the like.

So your game will work on 3dfx... as it''ll on PowerVR, nVidia'' 3d chips...

I''m not sure I totally agree with you guys here.I''ve put out my terrain demo and all the complaints came from people with 3DFX cards.They say that it doesn''t work well or not at all.They may not have the updated drivers,I do not know. Maybe it''s got something to do with my programming.But my demo worked on all other cards.
If you guys know why this is,then please drop me an email by all means.If you want to check out the demo on your 3DFX cards then goto:

I own a Voodoo3 3000, anything that NeHe has put out I can''t run, until recently. Those with 3dfx cards sometimes have troubles (they have always had trouble with their opengl implementation). Only until recently, (like yesterday actually) could I run the NeHe and alot of other OpenGL programs because I downloaded the latest drivers from 3dfx.

Before that I had the most recent drivers (the version before the one that just came out) and OpenGL didn''t want to work with them. The exception was Q3A and I think that is because they used a MiniGL (I could be wrong)

Actually Q3A uses the full ICD, but 3Dfx has made damn sure that the game runs on their cards. If they didn''t they would loose a lot of sales.

As I recall, the voodoo cards don''t like it when you pass OpenGL poygons which lay partly or completely off the screen when transformed. They slow WAAAY down when this happens, which means you basically have to do all 3d clipping yourself on these cards. Please correct me if I''m wrong on this one, I can''t really remember.

As far as I know you''re rigth.
This was one of the main advantage of the PowerVR chips against 3Dfx ones...
PowerVR chips does the clipping for you :o)

Anyway both the 3dfx and PowerVR chips are on the downside of the Pc market.
(Althought the Dreamcast, ST set-topbox and N@omi arcade board are powered by PowerVR processors.)

Don''t know why the older drivers don''t work with OpenGL...
I know best PowerVR technology than 3Dfx stuff.

The good news is that NOW all cards (except very old ones)should work with your OpenGL app.
