Updated Dawn OpenGL Wrapper

Ratchet · Jun 30, 2003, 02:37 PM

Some of you might have noticed that when you're running the Dawn demo on your Radeon, Dawn doesn't have eyelashes. We recently received a new version of the wrapper which fixes that, and got a few additional comments from "The Guy" on how the wrapper works:

How it is done.

NV programs are parsed and tokenized then ARB programs are generated.
It is mostly straightforward instruction to instruction mapping.

Fragment programs in Dawn are short, mostly FX12 and no sweat for R300.
Reads from normalization cube map are detected and replaced with DP3/RSQ/MUL.
It improves quality because it removes graininess. Speedwise its about the same,
look at JC comments.

Vertex programs in Dawn are quite long, use lots of matrices, array
addressing and many vertex attributes. They map extremely well from NV to ARB,
even some ARB GL tokens have the same value as NV tokens.

Download the updated wrapper.

You can learn more about the "ATI Dawning" patch, its system requirements, installation and compatibility information, and check out a few screenshots in the original article.

Discuss this in our forums.

I have donwloaded the wrapper here -> http://www.rage3d.com/content/articles/atidawning/ and did like it was explained.

When I start fairy.exe in the /bin (where I copied the wrapper) it tells me "This program requires an NVDIA GeForceFX-class GPU or better to run. Unsupported features: NV_point_sprite"

What did I do wrong?

[I have a 9800 SE AOW with modified drivers for 8 pipelines]

I believe this wrapper doesn't work with newer Catalyst drivers.

The Dawn demo doesn't work with the latest Catalyst drivers due to ATI having removed support for that nVidia OGL extension you mentioned. There seems to be a work around, but I haven't verified if it works or not. See this thread in our forums:

Nvidia Does it again, A game called bridge It will only run on nvidia cards, hopefully someone will create a wrapper similar to this one to make the game run on Ati cards as well
