    SpongeForge

    SpongeForge

    A Forge mod that implements SpongeAPI

    A Forge implementation of the Sponge API. SpongeForge uses Gradle as its build system. The repo includes the Gradle wrapper that will automatically download the correct Gradle version. Local installations of Gradle may work but are untested. To execute the Gradle wrapper, run the ./gradlew script on Unix systems or only gradlew on Windows systems. In order to build SpongeForge you simply need to run the gradlew command. On Windows systems you should run gradlew instead of ./gradlew to invoke the Gradle wrapper. SpongeForge is the implementation of the Sponge API on the Minecraft Forge platform. Recommended for running plugins together with Forge mods. The purpose of the Sponge project is to create a plugin development framework for Minecraft: Java Edition. Sponge is being created by a global community, and its open-source nature means anyone can participate.

    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. User Guide: http://origamieditor3d.sourceforge.net/userguide/en/index.html
