Hello Universe 2D 3D Translation

Question

of course since i hate using command prompt, and i dont understand how the hell it works, i cant get JAR to work, so i cant compile this(which means i have no protection from anyone claiming it as their own.. i dont really care now that ive seen what Java 3D has to offer), but i made this program based on a few formulas ive found(this is before i knew about Java 3D), after i found out about java3D, ive looked all over for a Java 3D tutorial because thats basicly how i learn everything in java, unfourtionally i couldnt find one. Anyways i was hoping if anyone would be so kind to translate this code into the Java 3D form(its like the Hello Universe Demo at Java.net)

}basicly... if you havent read through the code... arrow keys and mouse drag rotate the shape and - and = move the shape, there are a few bugs which i have to work out, there is another shape(located in the commented array) but if you use it you have to change variable sides to 2 instead of 3

Answer 1

Hi some-guy94 :-)
Both checkboxes concerning 3d acceleration are active, with vmplayer and also with virtualbox. For the last one, I've also spent 128 MB of graphical memory, but no way to make that f****g xmoto working in an arch guest with a reasonable speed.
Ubuuuuuuuuuuntuuuu, one night before halloween, what's wrong here :-)
Lots of love to all
Eddi
