Interesting, I wonder which version will AmigaOS 4.2, it was said would be released with OpenGL

Afaik, mesa implements up to OGL 2.1. To use full opengl (up to 4.x) you should do a proprietary port of mesa, epanding the actual functionality.

Nice graph about release cycle of Direct-X and OpenGL specs. How it makes OpenGL more advanced? Also remember that Direct-X is LOT more than just a Graphics API.

@AmigaBlitter

OS4.2 Gallium ,but still need to Mesa?
acknowledge that I am a little confused

Gallium3D is a plattform indipendent driver framework for graphic cards.(low level)

Mesa is an open source implementation of OpenGL( right now somewhere between 2.1 and 3.0)

So Gallium is for the performance and Mesa is for compatibility with OGL.

Recently Mesa 7.11 has been released, adds many features, development is steady, wikipedia states the following:

"Mesa 3D supports OpenGL version 2.1,along with several extensions from OpenGL 3 and 4"

From 7.11 release notes. "Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by glGetString(GL_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 2.1.". I would trust that bit more than wikipedia.

What's the current state of opengl on Amiga OS4? Isn't it at 1.2 or 1.3? At this rate, AmogaOS will get opengl 2.0 compatibility around the year 2025.

@Rose
The fact that not all features a re implemented in all drivers is true but it is Gallium that gets the most attention.
Wikipedia it's an easy and friendly site to consult (and I mention it if I see the information is correct albeit not too specific) the public version 7.11 doesn't feature what's being worked on "in-house" but support for up to 3.0 is expected for the next release in January with up to 3.3 soon after (4.x has some very minor preliminary feature looked upon right now).

On further positive news HW video acceleration will also be included in the next release and the merge of König's 19000 lines of code with the main Gallium/Mesa branch has been performed last month (see THIS submission for further detail).
Acceleration is done through shaders as the UVD stuff isn't public domain/open source.

@ferrels
AmigaOS Gallium implementation will be included in OS4.2 which will ship with the X1000.
Judging from the ads in Amiga Future, the X1000 should arrive in 2011 thus an educated guess would have the X1000 along with OS4.2 (with Gallium) available within 2011 Christmas period.

@DAX

You are too optimistic. I think x1000 will not come before 2012.

@AmigaBlitter

And thus, harder for OS4 to have a port!

The Friedens are strong in graphics and OGL, and Hans in working on graphics driver. So i guess we can hope for a good port. I'm eager to see progress in this side.

It is a good news, because now the 3D engine and power is in Microsoft's hands with their Direct X.

Do you read "le avventure di zio paperone" too?

Lol


I think they can manage to do a good port.

Scrooge McDuck is also more advanced than DX11 ? :)

Seriously. How OpenGL is now advanced since your picture only reflected the release cycle, not features.

He is. Gyro Gearloose have managed to create a supercomputer with super graphics for him.
