We currently are using sview

http://www.sview.ru/en

for general purpose viewing of 3D material in the Nvidia switched 3D 
system.  This replaces vlc for 3D video (moving) images, and a number of 
static image viewers (e.g., eog) for jpeg files and the like, but only 
for stereoscopic 3D material.

Is there any better such viewer for SL6x?  sview does not work hard to 
maintain compatibility with TUV EL and clones thereof, but rather with 
non-enterprise Linux releases.
