Explore photometric stereo techniques for 3D reconstruction using Rust and WebAssembly in this 26-minute conference talk. Dive into the principles of shape from shading, perception of shading and reflectance, and 3D reconstruction from images. Examine a practical application of photometric stereo on the Bayeux Tapestry. Learn about code organization, library configuration, and the integration of Rust with WebAssembly for web-based implementation. Discover how to leverage JS workers to call WebAssembly functions, enabling efficient 3D reconstruction in web browsers.
