The problem was: the Blender default camera has DOF distance as 0.0. Since we are using this as Focal Length for the stereo calculation we had terrible stereo by default.
Fix: whenever DOF == 0.0 we use focal length as eye separation * 30.0 (known to be a reasonable value)
Now the default eye separation value is 0.10 (reasonable for games with 1 meter == 1 B.U.
The focallength used is the camera focal length (DOF settings). It allow you to even use different focal lengths for different scenes (good for UI)
In order to change it you can change the camera focal length or use Rasterizer.setFocalLength.
If you use the Rasterizer method it will use this value for all the cameras.
ToDo:
- Blenderplayer settings
- Update wiki documentation (any volunteer)?
* Note to stereo fans:
I don't have a real stereo environment to test it (other than cheap cyan-red glasses). If you can give it a try in a more robust system and report bugs or problems with BGE current system please let me know. I would be glad to help to make it work 100% by the time Blender 2.5 is out.
For the record, BGE is using the method known as 'parallel axis asymmetric frustum perspective projection'. This method is well documented here:

GLEW update to version 1.5.1 [11-03-08]
this opens room for Geometry Shader support.
* - Brecht, Campbell told me you did some local changes in order to make it right in Linux. I get to you in order to know what those changes are (or feel free to commit them directly)
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.
* first working changes to get blenderplayer linking
* blenderplayer/ moved into source/ (CMakeLists.txt changed for that too)
* added externs for bprogname to gp_ghost, so that it links properly
* Add BGE_CXXFLAGS so we can get rid of hard-coded BGE compiler settings. This was only done for windows, but now linuxers and osxers should be able to set BGE-specific optimisation too. See the windows default configs for example.
Logic Panel:
- world settings (moved from world)
... that includes physic engine selection + gravity
- game player (from gamesettings, it wasn't wrapped)
- stereo/dome (from gamesettings, it wasn't wrapped)
... separated stereom into stereoflag and stereomode
- properties
... (didn't touch it)
Buttons Game Panel:
(wip panel)
- Physics (moved from Logic Panel)
... it will be a datablock in the future (right Campbell ?)
- Material Physics (not currently implemented)
... a datablock link to the materials of an object + the dynamic physic variables
* NOTE:
in readfile.c::do_version I couldn't do if(scene->world). There is something wrong with scenes with an unlinked world. So so far we are ignoring the old values....
* ensure all SConscripts are ready for win64-vc (where necessary).
* ensure we have proper _DEBUG flag for Python when we're doing a debug build.
* some cleaning up of linking etc.
* ensure /EHsc is there for game engine modules.
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
User guide:
http://wiki.blender.org/index.php/Dev:Source/GameEngine/Fisheye_Dome_Camera
Fixed two bugs from original patch:
- deleting a text will clear the warp field from Game framing settings
- removed spurious black dots along the edge of the cube map in the gameplayer
Known limitation:
- resizing of the screen doesn't work in the gameplayer
Known bugs:
- Texture with reflexion are not rendered correctly
- Spurious problems with light
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.
vector in perspective mode. This is default OpenGL behavior, but
by now this optimization is really insignificant. Works in both
the 3d view and game engine.
