Hi.
Got a problem with vertex buffer.
It seems when I use wglGetProcAddress
on some of the functions on vertex buffers
there is allways a NULL pointer as the result.

Mabye I ain't got the right drivers.
I got NVIDIA card.
Could someone tell the reason of this ****.

And if this is cause of my NVIDIA drivers problem , where can I get the new ones.
I was trying to search for some on NVIDIA.com
but none.

THX

Which functions? Please list them *exactly* as you name them in the wglGetProcAddress calls.

Also indicate your video card, OS, system, etc..

Have you queried the extensions list using glGetString ?

none of the functions work.
glBindBufferARB
glGenBuffersARB
glBufferDataARB

Is it a TNT or TNT2 ?
I have seen ARB_vbo supproted on TNT2, but not on TNT.

ARB_vp is even supported on TNT (in software, of course) but I haven't seen ARB_vbo. Could be done in the latested driver though.

I think it is TNT.
That's not good.
I think. I guess I need a ne GFX card

Well, try downloading and installing the latest driver, it costs you nothing and could work.

Yes GFFX supports ARB_vbo, but you don't need to go that high (not that I want to bias your opinion).
If you want to take a look at a list of hardware that supports vbo, you can take a look at deplhi3D.net where there is a non-exhaustive but very useful list.

LOL! NVidia's managed to really confuse things with their naming schemes. . . I think by "GFX card" the only assassin was refering to "graphics card", not the GeforceFX, specifically. . . http://www.opengl.org/discussion_boards/ubb/wink.gif

It was Graphics card. Not GeforceFX.
