- Hi, and thanks for trying out my TREKMO (TREK DEMO, if you didn't
- figure it out yet :-) demo. The demo is just a simple framework
- around my current 3D rendering engine, with a Gravis UltraSound
- sound system included.
-
- The demo is targeted to fast 486 machines, preferably 486/33
- with local bus display or any 486/66 machine. Running it on
- 386 machines is possible but not very enjoyable. The demo will
- also need some 400 kilobytes of memory and a register-compatible
- VGA display.
-
- The demo will loop forever (or until you press ESC) unless you run
- it with "trekmo -once".
-
- If you want to hear the music, you must have a Gravis UltraSound
- (GUS) card with AT LEAST 768K of DRAM. You also need to have the
- ULTRASND environment variable set, and you must have run ULTRINIT
- before running the demo. If you have less memory on your GUS, I
- recommend you rename (or delete, but then you cannot distribute
- this demo) the BANK0.GUS file so that music will not be played.
- You should seriously consider upgrading your GUS to a full 1MB,
- though!
-
- If you do not have a GUS, I suggest you get one :-). If you are
- certain you will not, you can delete the BANK?.GUS files to
- save disk space. Do NOT distribute TREKMO without those files,
- though.
-
- The demo memory usage consists of the following areas:
- - PMODE 2.4 header: 14968 bytes
- - main code & data area: 66957 bytes
- - NCC-1701D data: 30684 bytes
- - Romulan Warbird data: 61268 bytes
- - song events: 62460 bytes
- - 16-bit Z-buffer: 153600 bytes
- -------
- 389937 bytes (381 KB)
-
- At the end of the demo (you can end it any time by pressing ESC)
- you will see the average framerate. Below is a table of machines
- I have tested the demo on. If the framerate on your machine is
- much below 20 fps, you have too slow a machine for TREKMO, sorry.
- The GUS music will have no effect on the framerate.
