Volumetric Caustics

Volumetric caustics also known as volume caustics, is a type of caustic lighting (raytraced reflections from refractive objects). They are used when its not just the surface of an object that refracts the light, but the light direction changes one or multiple times as it passes through the inside of the object. In other words, it is used with volumetric modelling.

This is the type of caustics that is able to create complex patterns of lighting from interactions with moving fluids and gasses, where the refraction does not just happen at a single point, but at muliple, each point triggering a caustic trace, and potentially creating a complex caustic network.

Because of the high processing overhead of volumetric caustics, they are best kept to limited areas, where possible. Whilst they do produce intensely realistic reflection patterns, they are extremely computationally expensive to render.
