Caustics Generator

Caustics Generator is a lightweight software application designed specifically for helping you generate water caustics textures. Its aim is to simulate the effect of light refracting through water and render images which can be used in real-time graphics, such as games and simulations.

What’s more, the generated water surface is tileable, which means you can tile individual images both horizontally and vertically, while an animation sequence loops in time.

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.

You can copy it on any USB flash drive or other devices, and take it with you whenever you need to render caustics light patterns on the breeze, without having to go through installation steps.

Caustics Generator gives you the possibility to alter several caustic parameters pretty easily, thanks to the built-in sliders, namely depth, intensity, amplitude, frequency, and time. The current settings can be exported to CST file format, so you can quickly upload them in your future projects.

What’s more, you are allowed to enter a user-defined number of frames, specify the size of the image (up to 512x512), alter the background color based on the RGB values, automatically preview the changes applied to the image in a dedicated panel, pick the saving directory, as well as export the water caustics texture to BMP file format.

Caustics Generator comes bundled with a handy suite of features for helping you create caustics light patterns with minimal effort.

If you are looking for advanced options, such as commercial use, animation playback and tiling preview, motion blur, high dynamic range image output (EXR), fast rendering of animations on multi-CPU computers, surface height and normal map output, and unlimited image size, you may check out the professional version of the program, which can be found here.
