OPENRNDR is an open source creative code framework for Kotlin / Java 8+ that simplifies writing real-time interactive software. First developed in 2010 at LUSTlab under the name RNDR, the idea was to create an in-house framework that was versatile enough to sketch in, but at the same time be robust enough to deliver production-quality interactive media installations. It takes the creative mind set of a designer or artist, and combines that with the power of IT-grade software.
When LUST closed doors in 2017, the newly formed studio RNDR continued development and changed the name to OPENRNDR, a precursor to its goal to distribute the software under an open source license. They translated the framework from Java 8 to Kotlin, created the guide, and developed the API documentation and launched the framework officially this month.
