Okay, guys! I changed my mind!

I am gonna release an alpha version of Mesa-5.1 + Glide3x combo, for testing purposes. I just neeed to talk to Amigamerlin and Koolsmoky!

The point is, having an "official" Mesa release to back the 3dfx driver up has its advantages (less bugs). But since Mesa-5.1 is not so hasty to get out the door, we might take this opportunity to fix some bugs of our own, via extensive betatesting!

However, I will expect more detailed feedback. Not just "this feature doesn't work you stupid muthaforka". If that happens, then, ohwell, bad things might happen as well.

Stay tuned. It'll be out in a few days!

Regards,
Daniel Borca

thats great!

cant wait to test a clean build of MesaFX 5.1
i have compiled this thing, but only with some things missing (i "fixed" the errors by outcommenting the lines giving the errors ;) ). of course this causes serious troubles, but at least i got ss-se, hl (with texure errors) and il2-sturmovik running (minor errors and slow).



the main errors where:
fxg.obj : error LNK2001: unresolved external symbol _txPalToNcc@8
fxg.obj : error LNK2001: unresolved external symbol _txMipQuantize@20
fxg.obj : error LNK2001: unresolved external symbol _txImgQuantize@24

this refers to be some error with texus, but i dont know what went wrong (what do i need from texus?).


so far, besides the errors mesafx gives a nice screen output :)

You need the texture codec! Try and grab the Glide3 from SourceForge as well! The code is there! Or, wait for a few days! I'll upload both Mesa and Glide DLLs!

Does anyone knows whether nVidia (or any other company) holds any claim/patent on FXT1?


FXT1 is the property of nVidia but doesn't require any license for use and is royalty free, it is open source, so you can use it without having to worry about any patent infringement.
Intel is using the GL_3DFX_texture_compression_FXT1 extension for their integrated chipsets.

quote:
PS: specific texture compression is still on debate, because of possible legal issues.


Does this mean no support for GL_EXT_texture_compression_s3tc and GL_3DFX_texture_compression_FXT1 ?

quote:
Let's make things clear: no texture compression algorithm will go into Mesa at this stage!


So games which require S3TC won't work or is there a workaround to convert S3TC calls into something else?

quote:
The real-time compression/decompression will be done -- at best -- through a very special Glide3 library, with embedded Texus2. Bwahahahahaha! This way, you'll have to use our Glide3 at SourceForge.net!


Could you please elaborate on this?
What is Texus2?

Well, Intel affords paying, anyway...
Could anyone give me SOLID proof.. not just warm opinions about this?

Exactly!!!

I said no texture compression algos will go into MESA! I didn't say anything about GLIDE! And yes, there are workarounds... although not perfect!

Basically, it depends on what exactly must be licensed: API, codec or both?

Texus2 is an utility / library for handling images. Including texture compression.

still no alpha release... anyway, I have a suggestion for 3dfx MESA 5.1, fixing T-buffer support for Serious Sam. Now it doesn't work when motion blur is requested via ogl_iTBufferEffect = 2, and Croteam says it's due to bad drivers from 3dfx.

Why make trillions when we could make... billions?

Be patient! I sent the DLLs to the right person (look up )! It's a matter of one day or two!

T-buffer doesn't work in SLI mode. It's a HW limitation (both clearing & rendering). I fixed T-buffer clearing for SLI, but haven't had time to fix rendering. Still, I have a slight idea how to do it. There is hope... Nevertheless, tis a Glide issue, not Mesa!

You sure about that Dan? Cause the Q3A motion blur demo worked, and that was running a Voodoo 5 5500AGP in SLI mode...

Yup! I'm sure! the thing is, there is no direct connection between OpenGL notion of motion blur and Glide notion of T-buffer. I won't go into details, but I will try to explain my point better:

Texturebuffer allows rendering into a texture instead of the framebuffer. That's it! everything else should be the same. But, you see, no Voodoo can do this particular type of rendering using more than one chip.

Fortunately, OpenGL does not employ HW texturebuffer when doing motion blur. I don't even know WHY (the hell) motion blur is associated with texturebuffer. But you can ask 3dfx engineers -- they advertised motionblur as a T-buffer effect. Huh!?!

Yeah, I know...

Thanks for the kind opinion!!!

Have you tested it? We are also interested in positive criticism
