I haven't tried this one yet, but the first one sure looked nice.

I just wonder if you've tried some variations.
Shouldn't 16 bit integer be good enough for the water state? In that case you could use bilinear filtering to do the sobel filter with just four samples.

Or you could calc the sobel filter in the physics shader (from last state). And then store the sobel components either as a part of the water state, or as a second render target. And then just do the normal normalization per pixel. That should be possible with 4 samples att "half-pixel-position" and one center pixel, for physics and sobel.

And finally, it would be nice with a render to vertex array so that the surface actually would be displaced.

Just trying to keep you busy. ;-)

I'll be expecting that 9700 Pro any time now :P

Black Knight,
while getting reflections from geometry directly is hard there's nothing keeping you from rendering the geometry around the water into a cubemap and use that. Should be a decent enough approximation for most cases.

Beautiful demo... but somehow it managed to crash my computer (windoze xp pro) .. i lost no data and i wanted to go to bed anyway.. but i wondered how it could do this.

It ran fine for a while. (i have a 9600 pro with catalyst 3.7 drivers installed)
