This website demonstrates some great Java effects. There is one in particular I am curious about, a water effect. Any suggestions as to how this might have been done?

I don't know where to begin. Does it involve repeatedly going into a BufferedImage with a raster and making new images for display by moving the pixels around? Huh

Looks like the classic smooth/sharpen water effect.

Another appreciation for you DzzD, as well!

I still have a lot of questions, particularly along the lines of how to render the distortion, but I will hold off until I've had a chance to explore this code and the algorithm link further.

In case it's of interest, here's my version of this - http://code.google.com/p/praxis/source/browse/ripl/src/net/neilcsmith/ripl/components/temporal/Ripple.java

I used this a few years back for this project http://video.google.com/videoplay?docid=-1631892283027158552# - a webcam triggers the ripple effect, which in turn controls the manipulation of the audio.

Best wishes, Neil

Water effect can be really cool  Tongue.

My version is too complicated for that it does.
