This is the OpenGL-based compositing code. It is the primary and most powerful
|
|
compositing backend.

Sources and other compositing managers:
|
|
=======================================
|
|
|
|
- http://opengl.org
|
|
- documentation
|
|
- OpenGL Redbook (http://opengl.org/documentation/red_book/ - note it's only version 1.1)
|
|
- GLX docs (http://opengl.org/documentation/specs/glx/glx1.4.pdf)
|
|
- extensions docs (http://www.opengl.org/registry/)
|
|
|
|
- glcompmgr
|
|
- http://lists.freedesktop.org/archives/xorg/2006-July/017006.html ,
|
|
- http://www.mail-archive.com/compiz%40lists.freedesktop.org/msg00023.html
|
|
- simple and easy to understand
|
|
- works even without texture_from_pixmap extension
|
|
- claims to support several different gfx cards
|
|
- compile with something like
|
|
"gcc -Wall glcompmgr-0.5.c `pkg-config --cflags --libs glib-2.0` -lGL -lXcomposite -lXdamage -L/usr/X11R6/lib"
|
|
|
|
- compiz
|
|
- git clone git://anongit.freedesktop.org/git/xorg/app/compiz
|
|
- the ultimate <whatever>
|
|
- glxcompmgr
|
|
- git clone git://anongit.freedesktop.org/git/xorg/app/glxcompgr
|
|
- a rather old version of compiz, but also simpler and as such simpler
|
|
to understand
|
|
|
|
- beryl
|
|
- a fork of Compiz
|
|
- http://beryl-project.org
|
|
- git clone git://anongit.beryl-project.org/beryl/beryl-core (or beryl-plugins etc. ,
|
|
the full list should be at git://anongit.beryl-project.org/beryl/)
|
|
|
|
- libcm (metacity)
|
|
- cvs -d :pserver:anonymous@anoncvs.gnome.org:/cvs/gnome co libcm
|
|
- not much idea about it, the model differs a lot from KWin/Compiz/Beryl
|
|
- does not seem to be very powerful or with that much development going on
