Last week I did a visualization of the optical phenomenon known as “caustics”. It happens when rays of light gets refracted through a semitransparent object like glass, water, clear plastic etc. A well know example is the moving pattern of light on the bottom of a pool. I modeled a “stone” with Mudbox and rendered a simple animation using KeyShot. The guys at Luxion Inc. (makers of KeyShot) liked it so much that they made a blog post about it.
Let me know if you need any visualization where caustics would make a great effect. I.e. jewelry and glass objects.
