The vertex base ocean on the red mi note3(Qualcomm Adreno 510) , FPS 60

Technique:

• Projected grid for infinity water issue.
• Vertex shader Perlin noise (GPU base)
• Two normal map (medium and detail) for displacement issue
• RTT technique (Depth, Refraction, Reflection RTTS)
• Base Fresnel terms implement
• Foam edge process (depth base, no Sobel)
• Gradually disappear in the distance
• Normal distortion ( refraction and reflection)
• Deep and shallow water color
• use RTT technique to reduce ocean simulate huge pixel process overhead
