Sculpt 3D was the first ever 3D ray tracing application released for the Amiga. The first version was released in 1986, programmed by Eric Graham. The company Byte by Byte later released a port for the Apple Macintosh.
Sculpt 3D created still images, and a tool compiled an animation from these still images. Later the successor to this program, Sculpt 4D, added animation capabilities to Sculpt 3D. It allowed movement of objects by setting keyframes.
The first demo that showed Amiga raytracing capabilities was an animation of a juggler juggling three chrome balls. Even though the juggler was constructed out of spheres, the balls' reflections and movement made it look realistic. The juggler demo was generated on an experimental version of Sculpt 3D. The animation, released in January 1986, generated so much interest that the full 3D application was programmed. See the original animation below.
