    Origami Editor 3D

    Origami Editor 3D

    Virtual paper folding program

    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.

    Human AI Net

    Human AI Net

    a Human and Artificial Intelligence Network

    We are going to teach eachother how to build AI and new kinds of game objects in this network using intuitive dragAndDrop. Its going to be a space for experimenting with fun and useful tools in new ways. Version 0.8.0 has some advanced components that will be working soon. The plan is a massively multiplayer space where we design, evolve, and play with game objects and do AI research together which controls those game objects along with directly playing the games. The main data format is, from xorlisp which is also in progress, immutable binary forest nodes, so if millions of people build that together nobody can damage or change anyone else's data since its all constant. You dont change variables. You create new data that points at existing constant data, as deep as you need it. I have mindmap lists, definitions, and 2 editable properties working that way with 2 kinds of event listeners that work locally. Its not a networked system yet, but the datastructs are ready to scale with it.

    Atari VCS (2600) Graphics Editor

    This code has been moved to GitHub

    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.
