flame-fitting

Why we included this project

FLAME is the head model behind a lot of current 3D face work, and this is the official example code for it. The repo walks through the full pipeline: loading the model, sampling random heads from its shape and expression space, then fitting it to sparse 3D landmarks or a full 3D scan. That covers the core of what you need for face alignment and scan registration, and the code is compact enough to read through and adapt into your own fitting loop. It also slots into the wider FLAME ecosystem, which includes projects for monocular face capture and voice-driven animation. One honest caveat: the model itself sits behind a separate license agreement, and the setup asks you to compile mesh-distance helpers, so budget some environment wrangling before the demos run. The fitting logic itself is well documented and has been reused widely.
