SGI Iris and AT&T Pixel Machine are the two high-end real-time 3D
Graphics machines that I know well.  We have one of each.

The Iris uses fast CPU(s) in combination with special-purpose polygon
rendering hardware.  The PXM is based on high-speed signal processing
chips.  A PXM advantage is that you can program everything inside it
(in C).  For example, John Amanatides and I wrote a ray tracer for it.
Others have done real-time textures, bump maps, environment maps, etc.
