Open Source Java Games

Origami Editor 3D is an advanced paper folding simulator. It uses a what-you-see-is-what-you-get interface and operates with a geometric abstraction of the Yoshizawa-Randlett system. Anything from a simple airplane to John Montroll's omega star can be folded in this editor. Origami files created with the program preserve the entire folding process, and they can be exported as folding diagrams in PDF, animated GIF files, or even as standalone Java programs displaying the origami in a 3D viewer when opened. The main purpose of this program is designing origami, but if you only want to learn how to make some origami figures, there is a set of built-in example files that can help you. Currently, there are 34 example figures available. Please note that this project was created for fun and still is a work in progress. The Discussion forum is open for anyone who wants to report a bug or suggest a new feature. User Guide: http://origamieditor3d.sourceforge.net/userguide/en/index.html

Update 4/14/2015 This version of the project was never fully realized. I have a much better tools and GUI that was never uploaded to SourceForge that I developed before I started down this road. I'm currently trying to track down the code. I recently logged in for a completely different reason only to notice that this software keeps getting downloaded... and there are probably lots of disappointed folks out there once they try to run it. Sorry about that. Anyway, long story short... I'm looking for the real code that's actually usable. Check the Atari Age forums. Once I find it, I'll post a message about it there. ==================================== Old comments ==================================== A cross-platform Java Application for creating, editing, and exporting Sprite and Playfield graphics for the Atari 2600 game console for the purpose of providing the modern Atari 2600 Homebrew community an enhanced graphics editor.
