[net.graphics] Request for device advice

rogerh@arizona.UUCP (Roger Hayes) (02/05/85)

I am soliciting opinions about framebuffers and graphics devices.

We have a Vax; we would like to have some graphics capability.
Workstations are a valid option.  We run 4.2, and we have a local
Ethernet.

The things we want to do are:
	Image display (raytracing)
	A first graphics course (Foley & Van Damm)
	Graphics utilities for, eg, display of data structures;
	algorithm movies.

Criteria are:
	resolution -- both spatial and color
	speed
	ease of interface to Vax
	ease of use (for both program and people)
	(cost is not an overwhelming issue)

What experiences have you-all had with various devices?  I welcome
both horror stories and paeans of praise.  (I also accept expert 
advice, but stories are more fun.)

	Thanks,
	Roger Hayes

We have SGI IRIS systems, a 1000 terminal and a 1400 workstation.
These are super machines, with enormous capability.  Furthermore SGI is
a company that has under development some astounding machines: hardware
shading, z-buffer, depth cueing, etc.  For applications work, for research
and teaching, you can't do better.

Yes, the IRIS machines are great, but only if used appropriately.  The 
reason that they are good is that they have pipe-lined Geometry Engines
to handle three dimensional transformations.  If all you want is a frame
buffer, and not fancy 3d hardware, then the IRIS may be over-kill.  They
seem comparitively slow when used as just frame buffers but I heard a
rumor that this problem will be fixed in the newest machines.
