? = should it be done?

See the HACKING file for KWin details. The composite-related sources are mostly
|
|
composite.cpp and scene_opengl.cpp (TODO: add comments and general overview).

Sources:

- 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
|
|
- 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
|
|
- libcm (metacity) : cvs -d :pserver:anonymous@anoncvs.gnome.org:/cvs/gnome co libcm
|
|
- no idea about it
|
|

TODO:
|
|
|
|
* Check/make it work with other gfx cards
|
|
- I've tested only with nvidia with the 9625 beta drivers so far
|
|
* latest stable nvidia drivers don't quite work, the COPY_BUFFERS
|
|
or REFRESH_DRAWABLES workaround from glcompmgr should take care of that
|
|
- the COPY_BUFFERS hack, if I'm getting it right, just creates a copy
|
|
of the X Pixmap first, so just always using ALPHA_CLEAR_COPY hack
|
|
in KWin should do the same
|
|
- I have absolutely no idea about other gfx cards, needs to be tested
|
|
* ati
|

* intel
|
|
* who knows what else
|
|
|
|
? Xgl support
|
|
- Compiz itself doesn't work when compiled with the libGL from nvidia,
|
|
it ships its own and links against it
|
|
? might be worth trying to use that libGL as well
|
|
- it may be just because of the special libGL, but when testing with Xgl
|
|
it even seemed non-conformant - none of the provided configs had
|
|
GLX_RENDER_TYPE with GLX_RGBA_BIT even though required by GLX
|
|
and other funny things. Indeed, it may be just me being still pretty
|
|
clueless about these things.
|
|
* is there a good reason to support Xgl? With the 9625 nvidia drivers
|
|
it seems to work fine without them
|
|
|
|
? AIGLX support
|
|
- no idea about this at all
|
|
* find out if it works
|
|
|
|
* XComposite overlay window
|
|
- X.Org 7.1 and newer have XComposite extension version 0.3, which allows
|
|
creating an overlay window to paint to instead of painting to the root window
|
|
- I still run older X.Org here
|
|
- the code in glcompmgr for this is in HAVE_OVERLAYS, stealing primarily from
|
|
here should be better since it's simpler and the code so far has been
|
|
modelled more after glcompmgr
|
|
- the code in compiz for this is in USE_COW
|
|
* use double-buffering with the overlay window - kwin already has code
|
|
for double-buffered destination drawable, but I haven't been able to test it
|
|
|
|
* when relying on extensions, detect that they are available
|
|
- some of the glcompmgr code probably depends on OpenGL/GLX extensions that may
|
|
not be always available, probably the same with compiz
|
|
* find out which code relies on extensions and add checks
|
|
|
|
? alpha clear hack
|
|
* find out if it affects performance
|
|
* if yes, try to find a better way of solving the problem
|
|
|
|
/ design framework for graphical effects
|
|
- modelling it after compiz seems to make a lot of sense
|
|
|
|
* make paintSimpleScreen() clip non-visible parts
|
|
- clip parts of lower windows by parts of windows above them, so that those parts
|
|
don't need to be painted
|
|
- similarly like in scene_xrender.cpp
