# lightdam

A DXR toy raytracer named after the light dams mentioned in Terry Prattchett's Colour of Magic.

## Scenes

Uses PBRT scene format, but supports only a very limited subset. Console output informs about shortcomings.

## todo & things to try

* write a proper readme

* denoiser

* materials & lighting

    * more materials

        * microfacet/lambert mix ("substrate")

    * support lights other than area lights [...]

    * sampling

        * simple MIS for next event estimation & direct hits

    * other light transport algorithms?

        * bidirectional path tracing

        * photon mapping

* upload more scenes to repository

* russian roulette per warp (can I query?) instead of per ray for higher efficiency

* ...
