Looks good to me. Thanks for tidyingup other parts of the code in GlutWindow.cc.

Now that the amplitude of the waves is larger, how about moving the camera higher so it's not covered by the waves?

Good idea, I'll do that when I rebase. Just playing around with the shader_param.sdf example - it's working with Metal so I'm part way through converting it to work with the wave shaders. I'll zip the model up and post it if it works.
