ChuGL

Strongly-timed 2D/3D graphics programming using Graphics Generators (GGens)

ChuGL (sounds like "chuckle"; rhymes with "juggle") is a unified audiovisual programming framework in the ChucK programming language. It expands ChucK's strongly-timed, concurrent programming model and real-time audio synthesis capabilities with a hardware-accelerated 3D graphics engine and API.
