Why is Indigo better than traditional renderers?

Indigo accurately simulates the physics of light which create many realistic effects that otherwise would have to be manually created. Because of this, it takes far less set-up time than traditional biased or 'global illumination' renderers. Simply creating a glass object and a light will produce beautiful caustics.

Effects such as:

* Depth of Field – the depth of field (DOF) is the portion of a scene that appears acceptably sharp in the image.
* Spectral effects – as when a beam of light goes through a prism and a rainbow of colours is produced
* Refraction – as when light enters a pool of water and the objects in the pool seem to be “bent”
* Reflections – from subtle reflections on a polished concrete floor, to the pure reflection of a silvered mirror
* Caustics – as in light that has been focused through a magnifying glass and has made a pattern of brightness on the floor
