Testing GPT-5.6 Sol for Ocean Rendering

The author notes that GPT-5.6 Sol can easily write water surface shaders, but struggles when the task scales up to a full ocean rendering system, particularly with:
- FFT: Used for more physically realistic waves
- Wind-driven wave generation
- Underwater effects: Caustics, refraction, reflection
- Foam rendering
To tackle "realistic water," the author spent a week learning modern water rendering techniques before using GPT-5.6 Sol to create a Three.js TSL shader. They also had Fable generate a Blender scene for Apo Island, eventually integrating everything together. The attached image shows the final result: a 3D scene rendering featuring the ocean, an island, and a yacht.
