Noise function in vertex programs.

I am working on water effects and looking for a good wave (or noise) equatation of 3D waves that possible to convert into vertex programs of GL.
So, I'll be very obliged for helping me,

    hmm,i dont know enough bout noise-function to help you,but you could use the sin/cosine functions to simulate waves.something like

    z = A*sin(x*t+a) + B*cos(y*t+b)

    could do the job,you just calculate the z to each (x,y) and increase t every frame or get t from a timer.slightly modifiy A and B increases realism,you could also add mutliple sin/cos functions with different coefficients.
