I've modified cvisual to create fullscreen and/or quad-buffered
stereo displays, and would appreciate it being tested elsewhere.
Download: <http://cs.anu.edu.au/~hugh.fisher/3dstuff/cvisual.zip>
Usage: display() now takes three new parameters:
fullscreen = int, default 0
If not zero, creates a borderless fullscreen window
stereo = int, default 0
If 1, creates a quad-buffered stereo display if supported by the
graphics card. Values other than 1 are reserved for other types
of VR display.
Both these can only be set at display creation, not later.
eyesep = float, default 0.01
Horizontal distance between left and right eyes. With the current
code the value has no real world meaning, this works for those
demo programs I've tried.
What works:
The fullscreen code works on RedHat Linux 7.3 and Windows 2000.
The stereo code works on Windows 2000 with a Wildcat graphics
card. It detects the absence of stereo under Linux, and I'd be
surprised if it didn't work, but we don't have a stereo-capable
Linux box.
What doesn't work:
Under Linux fullscreen windows never receive keyboard events.
Under Linux calling scene.hide() from within Python generates
an "Xlib : unexpected async reply" error message and the window
doesn't close. I've hacked the code in this beta to exit the
GTK main loop instead, which is OK provided you don't have more
than one window open.
