SGI just announced
a Linux porting effort for IRIS Performer
on the info-performer mailing list. Performer is an OpenGL-based
scene graph library optimized for visual simulation; it’s used in
areas like military and commercial flight simulation, as well as
the rides at
DisneyQuest). Release is expected before the end of 1999.
Performer is designed to drive the fastest graphics hardware and
run the most demanding graphics apps in existence, so this is very
good news for 3D graphics on Linux.
