There is a 3d shader running on GLES2. Waves are generated using noise, there are highlights, transparency and reflections. How do I implement foam? How can I paint the top vertices white? It is necessary that the vertexes that are at the top were white, and the degree of reduction of the white texture passed into the base texture of water.
