If you are new to both computer graphics and programming itself we suggest to first get your feet wet in the Processing language. Processing is specifically developed for the beginning programmer and offers a likely less steep learning curve. That said, we believe OPENRNDR is developed with an aim on simplicity and consistency and should not be super hard to learn. If you are experienced in Processing, you can find some posts in the forum comparing programs written in both environments.
OPENRNDR currently targets desktop platforms including macOS, Windows and Linux.
For macOS, we support versions 10.10 to 10.14. Older versions may work, but this is hard to verify in a structural fashion.
For Windows, we support Windows 10. Windows 8.1 may work, but we have no means to verify this.
For Linux, we support Ubuntu 18.04 LTS. Other versions and distributions may work.
OPENRNDR requires a graphics accelerator that supports at least OpenGL 3.3. This includes relatively old GPUs like nVidia 320M, Intel HD4000 but excludes Intel HD3000 for example.
OPENRNDR is written in Kotlin and intended to run on the JVM. We believe Kotlin offers a well-balanced programming language that is both expressive and easy to read.
The library can likely be used from Java 8+ as that’s one of the promises of Kotlin’s Java-interop, however the APIs that OPENRNDR provides are making extensive use of Kotlin-specific features that may not translate well to Java.
OPENRNDR is environment agnostic, however all our tutorial and reference material assumes Gradle and IntelliJ are used.
We have not reached the point at which we can make promises regarding API stability. OPENRNDR is pre-1.0 software, which implies we try not to break things, but at times we have to. We break in cases in which it is better to break than to continue with inconsistencies in or incompleteness of the API.
