I am using a package that allows me to model waves in gazebo. It does this using a visual material that has Gerstner waves applied to it. My goal is to detect the waves in this simulation environment and I figured that the gpu_ray should do this by sensing the visual shaders created by the material, it doesn't seem to do this though.

Can anyone help me with this problem? Am I just not understanding how the gpu_ray works?

Thanks!
