What Is It?

JRoller is a Rollercoaster simulation program. The original program was written in C with OpenGL 3D acceleration, but I have rewritten it in Java without 3D acceleration, and it runs quite fluently.

Some fulcrum points define the track which is interpolated between them ("periodic cubic spline" for the experts). The fulcrums can be changed in realtime. Try it out and let me know, if something goes wrong.

The program is freely distributable under the terms of the GNU General Public License

This file contains the source code and the compiled class files of jRoller. I apologize for the lack of documentation, but I think it's not that complicated. If you want to improve or modify the source code, feel free to ask me any questions about the code. You need a Java compiler to build it, and the Java Runtime Environment to run it.
