The BCC Caustics filter can be used to simulate the effect of light
refracting through a surface of water and projected onto a surface (like
moving water ripple reflections on a pool bottom).

You can use this filter to create many types of effects where rays emanate from
a point and are reflected or refracted by a curved surface.  For example, you
could use this filter to generate:

  • Moving plasma fields
  • Smoky particle effects
  • Waves in a pool
  • Animating geometric patterns.

The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
