There are many solutions, but the one you suggest I can't make any sense from. Down on the gpu you can use sin functions, and the osgparametric example is a good example of this so have a look at it. The osgparametric example creates a large flat mesh with z value of 0, then it uses a vertex shader to take the x and y quantities to compute the z value, along with a uniform that provide a time varying quantity that animates the resulting mesh.
