Curator Pick: Building a Real-Time 3D Face Mask
This clear, technical deep dive unpacks building a real time 3D face mask with MediaPipe, Threlte, and Three.js. Marek Jóźwiak guides readers from landmark recovery to UV mapping, and precise camera projection. The post explains topology, triangulation, and the canonical OBJ, with practical Node scripts and Three.js buffer strategies. It balances theory and code so designers and engineers can replicate the demo quickly. Wireframe checks, UV debugging textures, and performance tips keep the implementation robust. Expect readable snippets, clear diagrams, and a demo you can run in-browser today. Highly recommended for prototype work now.
You will learn how to align normalized landmarks to a perspective camera, reproducing object-cover and mirrored video. The article demystifies performance choices, such as using a mutable landmarks reference outside the reactive graph. It shows how to reuse static UVs, avoid runtime OBJ parsing, and compute vertex normals efficiently. The demo toggles texture and material modes, and exposes tweakable parameters for scale, depth, and rendering. If you build AR experiences or advanced facial visualizations, this walkthrough will save hours of experimentation. Apply these proven techniques to your Three.js pipeline, today with confidence, easily.
