Caustics Generator - Seamless water texture rendering

Caustics can be described as the light pattern you see at the bottom of a pool on a sunny day.
This tool will let you render such caustics light patterns.

The rendered images are ideal for use in real-time graphics such as games and simulations, but can also be used for architectural renderings, film rendering and advertisement renderings where water needs to be illustrated.

About

The patterns rendered by this program are calculated by simulating the effect of light refracting through water. The water surface is made tileable in both space and time. This means that you seamlessly can tile individual rendered images both horizontally and vertically. It also means that a full generated animation sequence will loop in time.

The rendered images can for example be used as realtime textures for games and animations but can also be used as light textures for film production, advertising renderings and architectural scene renderings.
