Onyx2 Demos - Volume 1

Instructions

To install demos - click on the CD icon - that should launch Software Manager and let you install the demos. If this doesn't work, then manually launch Software Manager and type /CDROM/dist into the Available Software Field, then press Lookup.

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

        ./portalis
To navigate click to the right or the left of a portal to turn, on a portal to go into it (or execute it), and on the floor to go back.

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 and tested for Onyx2 machines (running IRIX 6.4 or IRIX 6.5). Trying to run demos on any other machines will probably not work. Running on an older version of IRIX will probably not work either.

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...

[IMG] 		From Space to In Your Face II
500M of textures paged in on the fly... The demo starts in space looking at the earth. Zooming into Europe and later Switzerland reveals the Matterhorn - in 3-D. And now zooming into North America reveals the US and later Alcatraz!
