Added hlsl ocean shader. I think that will be the extent of my graphics/shader enhancement. There are a lot of other really cool ocean shaders out there, but most are too complicated and beyond my skill set to duplicate :)

Why do you need to use an FFT for the ocean shading? Is this more complex than a shader that uses sin functions to move up and down vertices?

[Found that there is a blog post describing this further]
Looks like a far more complex simulation of waves and choppiness, so that is probably why it is doing some more complex wave math.

That's correct. FFT is used for wave simulation, not shader.
