A glimpse into 3D desktops...
I’ve been talking about them, complaining about what you CAN’T do, about the troubles with 3D cards... Personally I’m getting a bit lost with all this. So, I’ve decided to compile all the information I could find out about those pesky 3D desktops.
A “what is” guide to 3D desktops
XGL
Essentially developed by Novell for SuSE and the first “elegant” 3D desktop, it came out with Compiz, a window manager that can replace Gnome’s (and now KDE’s and others) window manager. Allowing desktop rotations, window transparencies and deformations, it is nice-looking, fluid and can run on hardware more than five years old.
AIGLX
Championed by Red Hat and NVIDIA (amongst others) this method intends to add 3D acceleration to composite (ie. which can declare any element rendered separately and asks the hardware to assemble it all on screen) X—and this was accepted by the Xorg and freedesktop projects, so version 7.1 of Xorg has seen a nice AIGLX extension added. This solves the two main problems XGL encountered: 3D acceleration is still made available to applications, and video output can still make use of existing X extentions like xv.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
