#3D Studio w/ SGI Irisvsn
6 messages in this thread
Has anyone had any experience with running 3D Studio 2.0 with the Silicon
Graphics Irisvision board set? I've tried using the EXP driver that is
supplied with the boards, but the rendering seems to actually take longer.
There should be a way to utilize the Irisvision boards to there maximum
advantage in rendering, but I haven't found it yet.
Any Ideas?

Tim,
The IrisVision boards have drivers for accelerating AutoCAD, but
don't do anything for 3D Studio. Your rendering time is all on the cpu,
then pixels get drawn on the rendering display, at whatever resolution
you're in. The people to beat up are Silicon Graphics, who stopped selling
the board some time ago.

Tim,
You have my sympathies. A friend of mine also bought the Irisvision 24-bit
version and has had little use for it other than messing around with the
slick demos (esp. the flight stimulator <g>). I've played with it too and
he was also under the wrong impression that it could help him with
rendering – all it can do is act as a 24-bit display board as far as 3ds is
concerned and the included .exp driver would not work with 3ds2 very well.
I never found out if they updated the drivers for people who bought the
board.
I believe it can perform some interesting tricks with autocad models but
nothing with 3ds models.

I do have one application that requires the board set, so it is not a total
waste of money. But, like I've said before, I is hard knowing that there
is a Weitek sitting in there that isn't usable. Speaking of which, does
anyone know if there is a 50mhz version of the Weitek available, and if so,
how much does it improve the rendering speed.
Thanks,
Tim
Tim,
Sorry, no Weitek for 50MHz, and you can't cool down a 33MHz enough
to work reliably at that high a speed.

Thanks Kevin. I guess I'll just have to continue my quest for speed in
faster CPUs.
