For Philip Meyer
 

Dr Mr Meyer,

I need to know how you project the caustics onto the fish
in your image. I have ben trying to figure out how to animate the caustics on fish or the bottom of a lake, like what you would see
at the bottom of a pool..

Ive treid projection images on a spotlight where it does not shine on the ground, because projection images show the whole image
and the outline of the light.

Can anyone help

thanks
