Building High-Performance 3D Webs

Adding 3D to a website often results in a 10MB bundle and a 2-second main-thread lock. It doesn't have to be this way.

Progressive Enhancement The secret is loading the WebGL context only when needed. Use dynamic imports in Next.js to keep your initial bundle small.

BufferGeometry & Shaders Don't use standard materials for everything. Custom GLSL shaders are significantly more performant and allow for 'Brutalist' effects that look unique without heavy textures.

Optimization Checklist 1. Use Draco compression for GLTF models. 2. Limit the pixel ratio (1.5 is often enough). 3. Disable antialiasing if using post-processing.
