In 2009 vade and I developed the VVFFGL framework which provides FreeFrame GL support for VDMX. Vidvox have open-sourced our work: as well as the framework there’s a Quartz Composer plugin for running FreeFrame GL (and older FreeFrame 1.0) plugins in Quartz Composer.

A plugin for Quartz Composer to misrepresent pixel-buffer data on the GPU.
