Optimizing 3D Model Loading and First‑Frame Rendering with Three.js, ZIP Packaging, and WASM Decompression

By compressing GLB files into ZIP, extending Three.js loaders to unzip via a Rust‑compiled WASM tool, encrypting small buffers, and caching morph‑target shaders while spreading mesh rendering across frames, the team shrank model size from 50 MB to 11 MB and cut first‑frame render time from 7 seconds to 0.6 seconds, reducing overall page load from 15 seconds to 5 seconds.
