Tessellated ocean shader

hey guys, was working on a tessellated ocean shader at work, figure I'd share the results.

Sorry, only video so far, gonna fix it up a bit and maybe release it for PCer to check out.

Pretty boss water shader... I was surprised at the tree size. I've seen trees three times that size for water that aren't half as fancy. It would be quite awesome if you could release the shader after fixing it up.

Ah, but if he used material function he would have a much 'smaller' tree.

Question, is there any way to do similar tesselation in dx9/10? How did Crysis tesselate their water in DX9 or on the xbox 360?

There is already a water surface primitive in UDK that does some of what is being done here. So I suspect they do something similar.

but does it dynamically tesselate at a distance? are you speaking of dynamicfluidsurface?

Hi, i have wirte a Tutorial for dynamic Tesselation of distance (dx11) and Ocean shader(dx9). Its works with static Meshes and Landscape Terrain.

assuming it would be done with a dot product, "camera world position" node, and "world position" node, and useing that to drive a lerp with 2 constant 2's for your fully tessellated and un-tessellated values into the tessellation factor of the material.

that would get a basic one going.
