Ladies and gentlemen, this is pretty much the same technical demonstration showed off in the Ultra 64 Pre-release promo/demo tape from Silicon Graphics around 1994, except it is running on a not-as-powerful Indigo2 IMPACT workstation instead of an Onyx visualisation supercomputer (or something similar), and might be a slightly newer version of it as well (the demo-disc I have is from 1995, but supposedly plenty of the demos in it were taken from Onyx demo compilations, according to the readme-file, so who knows... it could be older).
You will definitely notice a considerable amount of slow-down and performance loss in the demo within this video compared to the Ultra 64 promo video, and there is a reason why; this demo was probably originally released around 1993/1994 and designed for use with the RealityEngine2 graphics mostly used by the Onyx visualisation supercomputers around this time. This was before the Indigo2 IMPACT workstation - which I used in this video - was even available for sale yet, and the Indigo2 IMPACT (just like the normal Indigo2) was designed for desktops, unlike Onyx which came in a big deskside case (88 kg heavy) or a rackmount (which is the size of a refrigerator) in order to house all of the juicy graphics hardware and multiple processors. Because of this (even if the demo still supports a single processor), a lot of performance is lost due to there only being one processor and a less powerful graphics sub-system in the Indigo2 systems. However, despite the Onyx having much bigger memory buffer for both RAM and video memory, this demo does not require more than 4MB of texture RAM, which is what can be found in every Indigo2 IMPACT which has a Maximum IMPACT graphics board installed (like mine). This enables me to still display textures properly, even if the speed is not the best.
You will see me fiddle around in the environment, looking at scenery, seeing the starring sharks (named Baz and Chaz, but there is a third shark named Shaz in there too) and some fish. You will also see me toy around with visual parameters (like fog and wireframe rendering) since I was kind of curious about how you could modify the demo's appearance and performance.
If you are wondering about other details regarding this demo, feel free to post questions (or just comment too, of course)! I might upload a second video of this demo on request.
Interested in the Indigo2 workstation? Check out some of the other videos I have up as well! You can find system specifications there too..
The demo came from a demo compilation disc named "Demos for IRIX 5.3 All Indigo2 IMPACT™"
