interesting. I used grayscale images, originally created using special industrial embossing software in the "numerical control" area.Processing into a vector map should have more details of the quality.

We love love love this gao_jian11 :)

His great image here!

This has a little bit of everything:

EXR image assigned to a plane with vector displacement for water...power fractal for foam....too much reflection, but I was checking comparison to lake versus plane. I don't know because I didn't try yet, if the image would tile the same on a circular lake...to do list.

TG cube object with image shader and displacement for earth dam.
masonspappy grass from file sharing

Render micro 0.6/AA4 1920x1080, 1hr 33 min on my 4gig.

Yes, I know I can get the same displacement with TG internal elements. See my Icy lake images done only with TG. :) I was just experimenting. :)

Interesting experiments.
A couple of suggestions.
Try dropping the displacement a lot, by 70% to 90%. It's an inland reservoir, not the open ocean.
I'd also try plugging the original image map shader through several transform shaders,  scalled and rotated  (each going to their own displacement shader)
(works just the same on a water disk by the way)

You are absolutely right cyphyr.  I was trying to isolate at too small a scale here. There is an Atlantic ocean tgc  available in the library I think....I was just doodling. :)

yeah, made by Mr Lamppost way back IIRC but great hints from cyphyr...following the progress of this with excitement!

I know you all probably think I am so slow...but I really try a lot in between posts...not all of me is scatterbrained.

I reread Hanne's  water animation posts yesterday for some more insight:
http://www.planetside.co.uk/forums/index.php/topic,21618.0.html

So here now we have a distance shader to cut some of the whitecaps. Low res crop...I am trying to adjust the amount of foam and slope on the foam layer, etc, etc,.....

I put links in so perhaps you can see something you never saw, who knows?

ATM, I am flipping between erosion project, camera projected image with displacement, and this, and some snow stuff...and and and.... :)
