Could you build this?
Partial Setting up a Three.js canvas in the browser is simple, but authoring custom real-time volumetric caustics GLSL shaders requires specialized knowledge of optical physics and graphics programming.
What it would actually take: Requires Three.js or raw WebGL/WebGPU with custom GLSL shaders simulating light refraction and photon mapping/raymarching across volumetric water depths. The difficult part is optimizing frame-rate performance for complex mathematical caustic calculations (such as wave normal generation and screen-space light transport) in a single-file implementation. Requires expertise in computer graphics and 3D shader math.
