This a fork of Orihime オリヒメ and not affiliated with the original version.

Oriedita is a software used for drawing origami crease patterns. It comes with a wide range of tools to help you draw crease patterns.

Oriedita can simulate folding a crease pattern and show if a crease pattern is flat-foldable, and show a folded version of the crease pattern if it is.

The software is based on Orihime with added performance, stability and usage improvements. Notable improvements are:

• Making it possible to fold very complex crease patterns that would be impossible to fold in Orihime.
• Dark mode and improved Look and Feel
• Improved file save handling and better .cp support
• .FOLD file support
• Persisting application state
• Easier installation on Windows

Download the latest version from the Releases page.

Download the latest development version.

After downloading the latest version you can use the installer to install the software or run the jar using Java (at least version 17).

You should be presented with the main interface of Oriedita.

Use the mouse to draw lines on the crease pattern, using the buttons to change the type of the fold line, and use the button to try and fold the crease pattern.

Clicking on buttons will update the help box with a help text for that button.

.ori

Oriedita file format .ori saves the crease pattern, customized colors and the camera position. Recommended when developing a new crease pattern as loading it brings you back to the same state as you left it.

.cp

The .cp file format only saves creases (no circles or state). More lightweight and portable and should be used when sharing with someone else. It can also be opened in other origami crease pattern softwares.

.fold

The .fold file format is more advanced format like .ori and can be used across different origami softwares.

This section describes advanced topics such as custom configuration files. Not necessary for normal usage.

Configuration is saved to the following configuration directories:

• %APPDATA%\oriedita on Windows
• ~/Library/Application Support/oriedita on Mac
• ~/.oriedita on Linux and other systems

It should not be needed to access files in this directory yourself.

Button configuration is found in these properties files:

• hotkey.properties
• name.properties
• help.properties
• tooltip.properties
• icons.properties
• gif.properties

Placing these files in the configuration directory or in the same directory as the jar will override the values, allowing customization of hotkeys or translations.

Read the JavaDoc on javax.swing.KeyStroke.getKeyStroke(String) for more information on the format used for hotkeys. Wrong KeyStroke strings are reported to the consoleDialog.

The application state is saved to config.json in the configuration directory. It contains information about the application and is restored when the application starts.

To reset all options in Oriedita to the default state, remove all files in the configuration directory, see the Configuration section to find this directory on your operating system.

Some installations of windows use scaling to make everything larger and easier to use. This can cause Oriedita to become larger than the screen. Disable ui scaling to prevent this.

When running Oriedita from the jar, execute the jar as follwos:

java -jar -D"sun.java2d.uiScale=1" oriedita-vX.X.X.jar

When using the installer or portable installation navigate to the directory of the installation (C:\Program Files\Oriedita) and edit the Oriedita.cfg file in the app directory, add the following line at the end of the file.

java-options=-Dsun.java2d.uiScale=1

Orihime is an awesome tool that is used by origami designers to design new origami models. Orihime is developed by MT777 and can be downloaded from http://mt777.html.xdomain.jp/. Undertrox developed orihimeMod, which adds some extra features to the Orihime software, this version can be downloaded from https://github.com/undertrox/orihimeMod

Extended Fushimi (Husimi) Theorem (used in FoldLineSet) is a version of Kawasaki's Theorem for flatfoldability of vertices in a crease pattern, specifically for 4-crease vertices.
