Fedora Rendering Project; AIGLX *Updated*
Linked by Thom Holwerda on Mon 20th Feb 2006 12:22 UTC, submitted by Rahul
X11, Window Managers Updated: Fedora was right in the middle of announcing all this properly, so here is the updated item containing the official names. Videos included, as well as the inevitable 'Why not Xgl?'. "AIGLX is a project that aims to enable GL-accelerated effects on a standard desktop. We have a lightly modified X server (that includes a couple of extensions), an updated Mesa package that adds some new protocol support and a version of metacity with a composite manager. The end result is that you can use GL effects on your desktop with very few changes, the ability to turn it on and off at will, and you don't have to replace your X server in the process." This is part of Fedora's Rendering Project, and instructions on how to install all this are available too.

I don't think he misread you.

If AIGLX is better at any term at all, it should be in the short term, as it only patches in some 3D effects into a 2D environment, without disturbing much the current X code.

XGL(XEGL) is a more ambitious solution which aims to map all of the 2D environment over GL(EGL) and needs a much bigger overhaul of the X code.

Or that is the idea I have got out of that extremely indigestible acronym soup -- X XORG XF86 XGL XEGL GLX GL EGL DRI DRM XAA EXA AIGLX Cairo Mesa XDamage XComposite XRender ...

From the AIGLX wiki, this is not my understanding, AIGLX and XGL are said to be functionnaly equivalent.

When both are finished, they'll do the same thing, but the path to get there and the resulting architecture will be different.

What do you think XGL can do that AIGLX can't?

I might well be wrong, but I understand from the Fedora site that AIGLX's purpose is to make it easier to "use GL effects", while XGL tries to do accelerate all X graphics output via GL.

For instance, GTL+ talks to Cairo, and Cairo would talk to X via Render in AIGLX, with no 3D intervention, while it would directly output OpenGL calls via Glitz in XGL.

If this is true, both would allow funky accelerated window managers, but XGL would accelerate Gnome as well. Again, I might be wrong: this is all VERY confusing.
