- While I agree that the SGI is the machine to get for its graphics capability
- and speed, as well as VR options supported directly (Sense8, etc.), I am
- concerned that you are implying that there are not enough NeXTs around to
- be cosidered a viable platform. There are far fewer Indigo's than NeXT's,
- I'm afraid. Remember, also, that the strength of the NeXt doesn't come from
- the hardware, but from the OS. With NeXTStep 3.0's inclusion of Interactive
- Renderman, via the 3dKit of programming objects, and Distibuted Object tech-
- nology, it looks like NeXT is heading in the right direction for VR.
- If you are satisfied to play with VR demo applications, or are up to
- making a substantial time investment for VR programming, then any of these
- platforms will work. However, NeXTStep will allow you to quickly and easily,
- with very little traditional programming experience, add VR capability to your
- applications. The speed may leave something to be desired when you are
- dealing with highly textured 3D objects, but that's why NeXT has Interactive
- Renderman. Currently, wireframe objects are supported. When NeXTStep
- begins running on faster processors, fully shaded objects will work, too.
- Also, realize that NeXTStep 486 is due out very soon. A good choice may
- be a fast 486 (or, soon, Pentium) machine running NeXTStep. The OS will
- definitely ease the 3D modeling, and the hardware should be fast and cheap
- enough for "home brew". After 486, NeXT should port to other platforms,
- probably SPARC, but hopefully the R4000 architecture won't be too far behind,
- and we can all run NeXTStep on Indigo's. I feel this would be the very
- best machine for desktop VR.
- However, it's very easy to become too concerned with the "Lawnmower
- Man" model of VR. The immersive graphics technology is very appealing, but
- it is basically worthless without an underlying model for communication
- between objects in cyberspace. The development of this backbone technology,
- upon which various VR "terminals" can be run, needs to be a high priority
- for VR hobbyists, as well as researchers. That model will stick with us
- for many years, while graphical technologies come and go with the ever-
- increasing rate of technological growth. We can not let a few companies
- determine the way distributed VR will be handled in the future. Like the
- Internet, it should be a "grassroots" thing, and its form should be
- determined by consensus. Then, with an agreed-upon, platform and interface
- independent model for the cyberspace network in place, Virtual User Interfaces
- (VUI's? ;-) can be developed.
- Hmmmm...it seems my original intent of fact-clarification has been
- superseded by an uncrontollable need to spout out on the philosophy of VR:-)
