Phoronix: Mesa's OpenGL 3.0 TODO List Is Becoming Smaller

Via a commit to the TODO list concerning Mesa's support for the OpenGL 3.0 specification, Marek Olšák has confirmed that vertex texture image units for OGL3 are "DONE" and working on the R600 Gallium3D driver...

Beyond OpenGL 3.0, there's already 3.1/3.2/3.3 and even OpenGL 4.0/4.1 to additionally address.

Yes, but OpenGL 3.0 bridged decades of neglect and decay, while everything after that added relatively minor functionality. I don't think that it compares to the huge leap that is/was needed to bring GL 3.

OpenGL 3 will be the major milestone for Mesa. I can't wait.

The only items for attaining OpenGL 3.0 support that haven't been worked on at all are the float-depth buffers and depth format cube textures.

and float-depth buffers: now done. Thanks Marek. http://lists.freedesktop.org/archive...ne/009085.html

At this rate, maybe we should be shooting for GL 3.1 for the next release.

Call me a pessimist, but I don't see 3.3 or even 3.1 coming with the next release. The wiki describes each of GLSL 1.40 and GLSL 1.50 as "piles and piles of work" that will take "months", and doing a release takes some time even when the bulk of it is "done". Anyway, I'd be plenty happy to see GL 3 support solidify in time for the next round of spring/summer distro releases (I'm assuming that it will likely arrive too late for the fall/winter ones)

Which wiki is that? 3.2/1.5 will be a fair amount of work, but 3.3/3.3 is downright tiny. And I think 3.1/1.4 is fairly small, but I'm not 100% sure. Anyway, you're probably right that it's unlikely GLSL 1.4 would be finished for the next release, but we can hope.

Sorry; I certainly should have linked. I was getting that from MissingFunctionality

I think this just made me cum a little bit...

Thanks for the list and the sum-up! I agree with previous commenters, the leap from 2.1 -> 3.0 is huge in comparison to 3.0 -> 3.3. Even the step to 4.1 isn't as big I guess.

I do hope that the maintenance of the fixed pipeline doesn't drag down the momentum of working with the newer and leaner OpenGL.

All it took was more patents to stop caring about them; as mr. Bridgman showed, there is now even a patent for your lungs.

So I'm assuming that none of this will work, unless your distro vendor has a patent license, or you recompile it yourself with '-middlefingerToPatentTrolls:1', or something?

So if one wanted to be a total treehugger, what functionality would they miss? Texture compression and HW-float? Or much more?

Also; when is somebody going to patent HW-double as an invention, to be able to fully support the float without getting patent trolled?

Yep. 3.0 to 3.3 would be easier than the to do list that's left for 3.0. 4.0 can rot for 3 years before anybody notices.
