thanks for getting back to me.. I figured out the effect. The problem now is that When i change the color of the caustic effect to blk like yours, the graphic in flash is all of centered. If i keep it at defult it fine.. Any reason for this? Can i send you the 2 flash files to show you.. Thank you very much for all your time. Keep up the great work.

Eric, the water droplets effect on lab.andre-michelle.com that Alex mentioned is done in a similar fashion with the caustic effect.

All effects like this use a displacement map. I load the map from a sequence since I couldn't program the pattern. Andre most likely draws the rings with flash drawing API and renders the movie clip into a bitmap and then applies the transformation.

My suggestion to you is to learn the drawing API, how to use bitmaps and bitmaps affects. When you understand that, you'll know how to do all kind of effects.

Very interesting – I’ll try that!

I was think of using two bmps created with perlin noise – one horizonal, one vertical – then try out different blend modes and displacement map settings on top of your ‘reef’

Probably be pretty processor intensive – but you could work the perlin data small, scale up and then apply to the source image….

Mike, it’s possible to create some patches using Perlin Noise but I’ve been unable to create a realistic effect with it.

Real water caustics look like this:

Perlin Noise is good for turbulence and smoke; a small map with low complexity will create some patches, but nothing like this.

Alex, the effect on Andre Michele’s site is gorgeous, but it’s something different.
