Lambertian material lit by an environment map. Defocus blur is achieved using the thin lens approximation.

Indirectly lit sphere rendered using photon mapping. Irradiance caching
tremendously accelerates the rendering time, but leads to visible artifacts,
which can be reduced by the use of rotational and translational irradiance gradients.
Demonstrates the rough glass model by Walter et al.. The glass is filled with a slightly absorbing medium.

ubiquaque [lat: everywhere] is a physically based renderer written in portable C++.
It implements unbiased as well as biased rendering techniques and contains
heavy optimizations targeted towards current processor architectures.
