Usage

ORX is built against OPENRNDR 0.3.28, make sure you use this version in your project. Because OPENRNDR's API is pre 1.0 it tends to change from time to time.

The easiest way to add ORX to your project is through the use of Jitpack. Jitpack is a service that pulls Gradle based libraries from Github, builds them and serves the jar files.

To setup Jitpack support in your project all you have to do is add the Jitpack repository to your repositories {}. It is advised to have the jitpack repository as the last entry.

repositories {
    maven { url 'https://jitpack.io' }
}

You can then add any of the ORX artefacts to your dependencies {}:

dependencies {
    compile 'com.github.openrndr.orx:<orx-artifact>:v0.0.9'
}

For example if you want to use the orx-no-clear artifact one would use:

dependencies {
    compile 'com.github.openrndr.orx:orx-no-clear:v0.0.9'
}
