How fast can images be loaded into a Personal Iris?

512x512x8 * 10 fps = 0.25 MBytes * 10 fps = 2.5 MBytes/sec.
That is pretty clost to maximum speed for a 3.0 Mbyte/sec disk drive
I have not been able to get better than about 2 fps (512x512x24)
on a personal iris (but I have not tried extraordinarily hard yet--
just doing the obvious libgl stuff); that should translate to about
6 fps in 8-bit mode (which will have to be 12-bit color-map mode,
there is no 8-bit mode). This may be good enough for you.
There is a nifty machine from DuPont Pixel Systems that has an IBIS
10 MByte/sec disk drive married to an image processing system.
The demo at NCGA was pretty impressive. If 10 fps is a minimum
requirement, you will have to look for special solutions such as this.
Jim -- your best source for local info is Lee Butler, also located at ST.
