Three.js and Custom GLSL Shaders

Advanced WebGL rendering stack for embedding real-time ray-tracing and Gaussian splatting into interactive 3D user interfaces.

This stack leverages Three.js and custom GLSL shaders to move browser interfaces beyond static 2D grids. By integrating hardware-accelerated ray-tracing and 3D Gaussian Splatting (3DGS), developers render photorealistic assets and complex light simulations directly in the DOM. The workflow uses fragment shaders for per-pixel calculations: maintaining 60 FPS performance even when processing millions of points. Modern implementations (like those from Luma AI) prove that custom kernels can deliver fluid, responsive UI components that handle volumetric data with zero latency.
