Onyx2 Demos - Volume 3

Instructions

The demos will install into /usr/demos. From that directory type:

        ./portalis

There is Portalis help located to the left of the Infinite Reality portal - there is both Portalis Dev. Help and Portalis Help...

Enjoy,

Configuration

These demos are designed to run at 1280x1024. Running at other resolutions is somewhat supported, but can still give inferior results - demos running slowly, demos not running full screen. The demos are set up to run at any resolution as much as possible, but running at 1280x1024 is still the recommendation.

For demos that must be run on a 24" monitor (wider aspect ratio) the best resolution to use is 1280x720. This is know as the HDTV format 720p. Save this .vfo file in /usr/gfx/ucode/KONA/dg4/vfo and use ircombine...

These demos are designed to run in at least 512M of memory. A few will work with less but will not run well. A few demos have options that will use up to 1G of memory, but they are clearly marked. Portalis will detect the amount of system memory and only run demos that have enough memory.

These demos prefer 2 RM boards. The demos will all run with 1 RM but many will not run at full speed. 4 RM boards is even better but most demos will work fine with 2. For those demos that absolutely require a certain number of RMs, Portalis will check the system configuration and warn of problems as needed.

Many of these demos require 64M texture memory RMs. (But Portalis will check the system configuration and allow running any that don't have this requirement.)

These demos are set up to run on a single pipe machine, with a mouse and audio (only a few demos support audio). Support for multiple pipes (including support for SEOS and Panoram) and other input devices (like a Flybox) are now available. Portalis will prompt for configuration information (Portalis does as much automatic detection as possible).

Understanding this list

The question mark will bring up more information and help on the demo.

The thumbnail will bring up a large screen snapshot.

The number given is the size of the inst image. This will give you a general idea of how long the demo will take to install - but not of how large the demo will be on disk.

Title and description are pretty obvious...

	17 M	Boombox Optimizer boombox
	182 M	Crash Taurus Crash Analysis Demo - a visualization of crash analysis data. (The simulation to generate the data took 12 hours to run on a 16 processsor Power Challenge.) Large version needs 512M, small needs 256M.
	59 M	Geoscene Performer Volume and Surface of seismic data (for finding oil).
	7 M	Geoviz Animation about GeoViz - a program that move around and examine interpreted surfaces, well curves and the seismic volume. 3D visualization is the key communication link to accurately and visually share data and interpretations between all disciplines. Any surface can be textured with seismic or other attributes, assigned levels of transparency, and lit to emphasize subtle features.

	31 M	Miscellaneous stuff Miscellaneous necessary stuff for HighEnd Demos. This includes Portalis and its support files.
	39 M	Mix Simulation This is a playback tool for viewing particles moving in a velocity field. Included with this demo are two different simulations - a kiln and a mix tank.
	10 M	Neuro-Endoscope Most doctors are used to studying bodies from an external perspective, particularly after having worked on cadavers. As a result, they tend to have difficulty with spacial visualization when working inside of the body. This simulation provides the opportunity to develop a better sense of spacial perspective when working internally.
	11 M	OpenVision Animation showing OpenVision 4.0 - a new 3D Geoscience and Engineering Visualization Application.

	4 M	Pump Optimizer pump vs. Inventor pump
	33 M	Stanford Prosthesis This demo was done for Dr. Gail Lebovic at Stanford Hospital, in order to redesign a chest prothesis.
	22 M	TorsoFE (SCIRun) Defibrillation Simulation. This demo simulates implanted electrodes (shown with a model of the human thorax, including the body surface) to reset the heart to prevent/reduce the effects of a heart attack.
	90 M	Vis5D Weather Weather.

	8 M	Visible Human 64M of volume texture of pictures taken of a frozen cadaver (a prisoner on death row who donated his body to science). Also includes a Reality Monster prototype using three pipes to run up to three times as fast.
	6 M	Visible Human - 16M dataset 16M of volume texture of pictures taken of a frozen cadaver (a prisoner on death row who donated his body to science).
	21 M	Visible Human - 192M dataset 196M of volume texture of pictures taken of a frozen cadaver (a prisoner on death row who donated his body to science). Using 3 pipes as a Reality Monster prototype. Three pipe only
	14 M	Visible Human - Ear 64M of volume texture of pictures taken of a frozen cadaver (a prisoner on death row who donated his body to science). This is only a portion of the data (the ear area) but at the full resolution of the original data.

	19 M	Visible Human - Heart 64M of volume texture of pictures taken of a frozen cadaver (a prisoner on death row who donated his body to science). This is only a portion of the data (the heart area) but at the full resolution of the original data.
	1 M	Wave Equation Simulation This demo is an "interactive" program that allows one to explore the behavior of acoustic waves in a two-dimensional variable velocity medium whose density is constant. The user-interface takes some getting used to (i.e. unfrien dly, unfamiliar,etc.) but is easy to use.
	34 M	Zebrafly Surface analysis by putting a car in a room lined with flourescent tubes - and look at the car. This demo has 4 different vehicles and a much cheaper room than car companies use...
