Offers a diverse set of data structures, algorithms, and utilities to enhance OPENRNDR, including tools for 2D/3D cameras, color management, shape composition, animation easing, noise generation, and various computational techniques.
A growing library of assorted data structures, algorithms and utilities to complement OPENRNDR. Multiplatform, unless they deal with hardware or depend on binary libraries. Those are JVM-only.

To make use of these extensions clone the OPENRNDR template, uncomment the ones you need in its build.gradle.kts file, and reload Gradle. Cloning this repo is optional but useful to run the demos in each ORX folder, to study the source code, and to contribute to existing or new ORX'es.
First, build and publish OPENRNDR to the local maven repository:
Run (or import in IntelliJ IDEA and edit the run configuration).
# In openrndr repository
./gradlew publishToMavenLocal snapshot
This command will build and publish a snapshot of the next version of the library to your local maven repository. The exact version will be shown in the console output during the build process.
Now you can run the same command again but for this repository.
# In orx repository
./gradlew publishToMavenLocal snapshot
It will automatically use the locally published snapshot of OPENRNDR for building ORX and will publish ORX to your local maven repository with the same logic as before.
Once that's done, you can use the local builds of OPENRNDR and ORX in your openrndr-template by specifying the version that was published.
