I must be an idiot, I downloaded ''terrain.zip'', unzipped it, but I can''t find a classname that will run any kind of demo.. is there something I''m missing (other than a brain lol)?

Windows 2000, Service Pack 3, JDK 1.4.0, Java3D 1.3. Clicking on the JAR file produces the infamous selection list and the wonderful question ''Click the program you want to use to open ''demo.jar''''. Ugh. I wonder if this means there''s something messed up in my installation?
Yes, looks like your installation''s a bit dicky.
To run it from the commandline you can do
java -cp demo.jar demo.client.Demo
For fun you can try experimenting with a few switches on the commandline to see how it affects performance like
java -server -Xincgc -cp demo.jar demo.client.Demo
etc.
There''s also
java -cp demo.jar demo.client.Demo enablekeys
which enables some extra keys that to fiddle with the number of lights.
Various keys do things but the readme seems to have gone AWOL.

Assuming the jarfile has the appropriate manifest file, you can also just type ''java -jar demo.jar''. If you want to extract the classfiles (and whatever other files reside within the jarfile), they you can type ''jar -xf demo.jar'' (that will unzip them in the current directory).
So there are a lot of ways you can do this

Waaaaaaaa-hoo! Damn that runs fast on my system, I''m getting around 125fps in the "normal" areas and around 72fps in the "watery" spots. Very, very nice. I''m going to fiddle around with the keys a bit and see what happens, but it''s impressive.
Glad you like it! It''s largely fill-rate limited mind you, as is nearly everything these days.
I seem to recall that H resets your position,
the left and right keys spin around the view,
forward and backward move towards it and back again (but this will crash it if you allow too many polygons - it''s quite tuned for memory consumption),
Q and W increase/decrease the size of the lights,
D and F increase/decrease the number of lights. (Here you can really see the effects of fill-rate limits - every light adds 6 passes to the affected polygons).
The Lightweight Java Game Library has just reached alpha, if you want to help out testing it by the way.
LWJGL is at http://sourceforge.net/projects/java-game-lib

ah no, A and S do the light brightness, Q & W do something freaky with the light cutoff point to tune rendering speed vs. a bit of accuracy.

Hey, I''ll download the lib and see what I can find. I''m sure I''ll crash something in the process...

I´m really dumb or I missed something, trying to run the Terrain got
