ray tracing

Ray-tracing

What is ray-tracing?

A ray-tracer simulates the firing of light rays into a scene and outputs the result as pixels, varying the result dependent on whether an object is encountered, the object's shape, colour and texture, distance in the scene and shadow. Boring definition, but spectacular results.

The 3D modelling of origami pushes the modellers to the edge. None of the programs were designed for this task. Models formed from paper have depth but the paper has lots of surface, but virtually no thickness.
