Sculpt 3D is a raytrace application released in 1987 for Amiga computers programmed by Eric Graham.

[1] Sculpt 3D was one of the first ray tracing applications released for the Amiga computers.

[2] The first demo that showed the 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 animation, released in January 1986, generated so much interest that the full 3D application was programmed.
