Why we included this project

This is a compact reference implementation of 3D Morphable Model fitting, showing the whole chain from 2D video frames to a tracked 3D face mesh. It wires landmark detection, a morphable face model, and an optimisation routine into one demo app that runs on a webcam or a video file, and it can export the fitted mesh as an OBJ. The code is modern C++ built on OpenCV, Eigen, and Boost, so it reads cleanly as a study of how the pieces fit together rather than a black box. Keep in mind it is a research demo from 2015/2016 running at roughly 5 fps, and the author points to the actively maintained eos library for current work. For anyone evaluating 3D face reconstruction approaches, this repo is a useful historical and educational baseline.
