>> Where did you come up with this idea that the Indy performs "*7 times" >> faster Specmarks don't mean a whole lot on the SGI machines as their strength lies in their graphics engine, GL commands (as long as the software is written to take advantage of these) and bus speeds. I have one sitting next to me right now and they are one of the best at running 3d graphics or Multimedia stuff in their price range. You should see AutoCAD scream on this thing. Just wish they would port 3D studio to the INDY then objects in flics could become interactive.

Specmarks, especially SpecFP, mean *everything* when it comes to photo-realistic and near-photrealistic rendering in 3D. The only thing SGI has that comes anywhere near near-photrealistic rendering in realtime is the RealityEngine. Those machines are a steal starting at around $200K. The hardware garoud shading and even texture mapping in the medium-end SGI machines is great for VR, but it is little use for photorealistic animation other than for previews. Realtime previews would be a really nice thing to have though. I think if you look at what you can get for $10,000 or below, the PC still blows SGI away. But if you have at least $20K to spend on a machine, the SGI starts to look really good. Your net render idea sounds intersting.

PMJI, but reality engines are less than $100,000, list on the Crimson reality engine is $99,900 and discounts are available. That gives you 192 bits of color, 32 bits Z bufffered. It displays over 1 million polygons per second with hardware anti-aliasing and texture mapping. The Onyx/2 RE2 is the next step up in the reality engine series and list for $159,900. It provides over 2 million shaded points, lines, and polygons per second. These figures are low because they're based on the R4000 not the R4400, and the new T series will blow away the R4400. You should also keep in mind that the performance of these machines is based on screen rendering not processor rendering. The geometry engines handle the graphics and produce phenomenal displays for simulation and real time visualization, however when it comes to old fashioned rendering to disk so that you can dump frame by frame to tape, the geometry engines become relatively useless, and you're stuck with rendering on a single R4400 processor at the moment. Additionally almost all of the SGI based rendering packages only support single CPU's in their rendering pipeline. Softimage at $50,000 per seat becomes expensive when you put it on 5-10 machines. Anyone interested in the move to SGI should focus on the Indigo2 with the Extreme Graphics. The performance is great and actual rendering speed to disk is the same as the performance on the larger micros, i.e. Crimsons and Onyx systems. On a more possitive note Softimage is about to release a multi-processor rendering package designed by a team out of Berlin. It should finally make use of the multi-processor configuration of the larger Micros. I believe the ship date is around January 1994. We have thoroughly tested all of the above mentioned hardware and regularly benchmark various SGI based animation packages.

Only $99,000? And discounts too! If only I had a Porsche 911 Turbo to sell. Me, I'm still hoping to be able to afford a Pentium machine soon. Did you get my e-mail?

I just finished replying to it. It should be in your box by now. Paul

…oohhh. Stop. No…. Don't! All your talk about high-end workstations is getting me flustered. Most of us can only fantasize about the size of our systems. Time for a cold shower <g>

Excellent information !
