Title: Water ripples where objects make contact
Post by: sonshine777 on January 29, 2008, 02:27:59 PM
I have a nagging question about the water system. At some point will the water system show ripples where an object makes contact with it? Some examples would be a log laying on the shore or cattails growing in the water.

If not in TG2 maybe a plug-in?

yes I always wanted this feature....

vue has similar feature within ecosystem....it can influence the area around the object....

If there was a "distance from object" shader (or one could be built from the nodes), this would work.  I've wanted a similar feature for coastlines, where it would lay down "foam" (via a power fractal shader or image map) where the edges of the water meet land.

It's possible to achieve this using function nodes.  I have a project that I created a few months ago (still waiting to render... bring on the transparency, Matt :)) where I set up some nodes to create ripples in a circle emanating from a given point.  These could easily be stretched into ellipses to fit each object.

...and, o_b, weren't you the one who did the submarine with the wake around it in the ocean?

Well, if you'd build a vector out of the objects XYZ location, substract the "get location" output and use a vector lengt to scalar opperation, you've got a blending mask that you can use to mask the ripples (you might need to invert it though).

Ogre,

Did you use an image to mask the ripples of is it created with functions?

I used image masks.
