Today I was testing Blender's new camera tracking functionality together with Dynamic Paint wave simulator on soc-2011-salad branch.
I had some issues with tracking system, and eventually I had to use 2D markers instead of 3D ones and that required lots of tweaking. But even though tracking tools are still in early development, it worked very well after all. With this development pace I can just wonder what one can do with it by the end of summer. :)
Here is the final render:
What you see here is a Suzanne monkey head added to a real footage. Water particles and wave visibility could still use some tweaking, but overall I'm quite happy with the result.
I also noticed a nice Dynamic Paint waves test by CristobalAtria:
