[Visualpython-users] Beta Visual Python with fullscreen/stereo

[Hugh F. <hug...@an...>]

  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.
