it somewhat astonishes me that one of the announcements of AmiWest, namely the fact that OpenGL (in the form of Mesa/Gallium) is currently already in the planning phase and will be the next big field of work for the graphics team was missed by everyone.

To recap what we announced at AmiWest: The current field of work is two-fold (for the core team). Kernel work will include an overhaul of the scheduler (which will include things like scheduling policies on a task by task basis, and SMP). The graphics work will be Mesa/Gallium. The latter will first be ported and put on top of the current system, and in an additional step, will replace the current system (and provide wrapper functionality for the current graphics system).
As i understand from that quotes, its all only in plans. And its to early to say "being ported". That mean 1 or 2 years from now imho. But good to know, that Thomas say that its high-priority for now. At last :) Better later than never :)
The only think which scare me a bitl, is that "gallium/mesa will first be ported and put on top of the current system". I.e. again that "old gfx-system" which can slowdown all the stuff. But as i know Hans involved in all that work, so we have big chances that all will be fine. At least we will have shaders, and full-modern opengl, what mean real big cool games and apps. If speed will be good too, then it will be uber-good.

so the old project "nova" has been dropped in favour of gallium3d? i hope that not too much work already had been invested into nova...
@Hyperion it somewhat astonishes me that when announcements are made at shows like Amiwest no one in Hyperion (that would be Ben, right?) takes the time to summarize what was said (by Hyperion) and post it on the Hyperion website.
I'm quite certain that I can't be the only person who is interested but hasn't got the (money to attend) or time to sit and look at low quality streams trying to catch every word that is said.
@ChrisH Ontopic. Sounds great and a development in this field is needed. When was the release date planned to be?
Gallium3D provides a unified API exposing standard hardware functions, such as shader units found on modern hardware. Thus, 3D APIs such as OpenGL 1.x/2.x, OpenGL 3.x, OpenVG, GPGPU infrastructure or even Direct3D (as found in the Wine compatibility layer) will need only a single front-end, called a state tracker, targeting the Gallium3D API. By contrast, Mesa 3D requires a different back-end for each hardware platform and several other APIs need translation to OpenGL at the expense of added overhead.[7][8][9] Under Gallium3D, Direct Rendering Manager (DRM) kernel drivers will manage the memory and Direct Rendering Interface (DRI) drivers (now moving to DRI2) will be more GPU processing oriented. This will resolve memory management problems whose solutions are considered infeasible under Mesa
As of 21 September 2010, There are two Gallium3D drivers for ATI hardware known as r300g and r600g for R100-R500 and R600-Evergreen GPUs respectively. Initial support for the Evergreen GPUs was added to the r600g driver on 2010-09-10.[20] On 21 September 2010, major commits were made to the code to support Direct3D 10 and 11.[21] In time, this might offer the ability to use recent Direct3D implementations on GNU/Linux systems.
Yep, gallium sounds very nice and interesting. If we will have ability to use not only latest opengl, but also latest directx , then it will be something :)
As i understand from that quotes, its all only in plans. And its to early to say "being ported".
No. "plans" means they expect to work on it in the future. "porting now" means they are actively working on it - which they are! Yes, they are at the design/exploration phase (*), but that is part of the coding process too.
(* = synonymous with "planning phase", but thats a different than "planning to do something". 'Aint the English language wonderful!)

How on earth do you work that out? AROS got a port of Gallium by someone working in their spare time! So I think it should be possible for a team (possibly even with someone working on it full-time?) to get something usable relatively quick. (Although admittedly rigorous backwards compatibility testing for a public release will add delays that AROS may not have to deal with.)

Ummm, I thought it was known that Nova had been dropped for some time? AFAIR, they eventually decided against reinventing the wheel.
@kas1e Hans mentioned he was looking at it months ago, if you combine his expertise on graphic drivers with the work already done on Aros (which he can look at and learn from) you get only one thing: advanced 3D coming to AmigaOS soon

I plan to rectify the situation in the next couple of days with a show report.
Great! One advice: make a "news item" of it not just a forum thread!
There are many at AW that only come to see the news and avoid the forums in order not to get involved in another endless feud. If you make just a report on the forum, these people will miss the news.
