- So I've some question about the compatibility
- of SGI GL whith non SG machines:
-
- - which workstation do support (or will support) SGI GL?
- (I know that IBM-risc6000 do have them for instance)
-
- The IrisGL has been licensed to IBM for its workstations. It was also
- licensed to Nth Graphcis and DuPont Pixel Systems and they have products
- that are available for SUN and HP boxes.
-
- - the IBM-risc6000 I've seen didn't support spheres sublibrary
- doe's it happen cause the impossibility to support hardware
- drawing of spheres (as it happen for some (big) SG machine)
- on IBM machine or was only due to an uncomplete installation
- of the GL library on the IBM machine I've used?
- (We use spheres to represent atoms, of course).
-
- The spheres library is software and wasn't licenses to any other vendor.
- I know of no special hardware in SGI graphics accelerators for spheres.
-
- - are GL on machines different from SG fully compatible?
-
- Not fully. With the current IrisGL, different graphics boards have
- different capabilities and that shows back through the supported
- API for that board. There is a reasonable subset that works on
- all platforms.
-
- - is FORMS library compatible?
-
- The FORMS package is free software in source form. There should be a
- copy available on archive.cs.ruu.nl [131.211.80.5] with anonymous ftp
- in the directory /pub/SGI.
-
- What you probably want to learn about is OpenGL. That has been licensed
- by around 20 vendors and will be available on every major workstation
- platform as well as with Windows NT. The sample implementation went out
- on 30 June, and folks are working to get it into product release at quite
- a few places.
