Unity-URP-Ocean-Simulation

Unity URP Ocean, implementing Simulating Ocean Water by Jerry Tessendorf.

How to use

Download the project and open the folder as a Unity Project. There's a demo scene in Scenes/IFFTOcean_Sample which you can refer to. To integrate the ocean to your own scene, here's what you should do:

• Import your favorate shape to unity.
• Attach WaveManager.cs to the shape.
• Tweak the parameters in WaveSettings for your WaveManager.cs.
• Bake the scene's light so the ocean can sample from the environmental map.
• Adjust the oceam material in Materials/ to get a satisfied color.

Implementation detail

In short, I implemented IFFT in Unity's compute shader and used it to calculate the vertex displacement from the dispersion relation and statistical spectrum models from real ocean (Phillips spectrum). Please refer to my blog for more details.

How it looks like

What to do next

• Try other spectrum models.
• Add choppy waves computed from the transformation Jacobian.
• The ocean's material now is not very satisfying to me. Lacking sense of transparency and refraction.
• Offshore shallow water gradual change and underwater caustics
• Physical interactions
