How to use hw rendering on a Voodoo2 with OpenGL??

OpenGL OpenGL: Basic Coding
1

Don’t tell me to buy a new card…
I’m not able to accelerate my ogl apps (and NeHe’s demos too…): I tried glsetup, or downloading the latest drivers from 3dfx.
Both contain something like:
OpenGL® Driver Version: 1.0.0.0508 ICD
this isn’t the minigl driver, I suppose, this seems to be opengl, but nothing happens.
Do I need to obtain a specific opengl32.dll?

If somebody is coding with a v2, please give me some help…
Thanks

I think the v2 has lots of limitations : fullscreen, color depth (16 ?), no stencil buffer, limited screen size (800x600 ?) and so on. You should be able to get OpenGL hw accelerated but with the “wrong” settings do you get software.

Buy a new card.

Sorry. Couldn’t resist!

hey i dont know much openGL but i do know this…u need a new card. hehe. seriously though you got yourself and old one. well im not goona pretend like i know anything i odnt but i read somewhere that the old voodoo cards had a dual processer design and are incompatable with some OGL apps. but i saw that there was some way of fixing it with some code. oh well tahts about all the knowledge i have about OGL so i gonna shutup. hehe

P.S. get a new card

 P.P.S. Hehe

Are you putting the opengl32.dll in the same directory as your program file? Works for me on my wonderfully hi-tech Orchid Righteous 3D (Voodoo I).

I found this in another forum:
"this is how i do it:
go to WINDOWS\SYSTEM and copy 3DFX32V2.DLL to the directory where your executable is, then rename it to opengl32.dll,

remember your voodoo2 only works in exclusive mode so you’ll need to run your app fullscreen "

Ok… I tried it but it didn’t work.
I saw a file called 3dfxvgl.dll - oh, it contains ‘gl’ !! - and I tried with that…
It seems to work!!!
eh, no.
Another problem.
glide3x.dll (instruction not valid)
This pseudo opengl uses glide, that’s ok, but glide3 doesn’t works!
Now I’ll look for a good glide3x, thanks to all!

Ps: I found something similar, a mesa implementation, same errors with glide.

Glide isn’t a must, I think.

Visit this site:

The Author desribes a method, to reference the dll for your V2.

I’ve tested it. Works perfectly.

How did you got infos about the driver?

Sorry,i’m a real beginner =)

glGetString(GL_VENDOR);
glGetString(GL_RENDERER);
glGetString(GL_VERSION);
