Re: [Visualpython-users] Fwd: Vpython active stereo 3D -- Will it work with the new Acer Aspire 5738DG that has 3D LCD display screen?

Bruce,

The Asus 3D laptop (G51J) is so far the only other 3D display laptop, as far
as I know.   Here's a brief overview of it:
http://gizmodo.com/5407435/the-asus-g51j-3d-laptop-is-3d-done-right .  It
does say that the display is 120 Hz, so a 60 FPS rate is what it delivers in
its frame-sequential 3D mode.  It uses an nVidia graphics processor, with
nVidia's 3D software.

The Acer uses TriDef 3D software.   TriDef has a description of the kinds of
3D graphics that exist now:
http://www.tridef.com/display/profile/all.html.  The Acer apparently
has "line interlaced", as opposed to "page-flipped
(OpenGL Stereo)" that the Asus laptop has.    Maybe OpenGL does not support
line interlaced.
