Built at last, built at last, thank God almighty, I’ll be built at last… According to Popular Science:

Developers at the Max Planck Institute for Informatics in Saarbrücken, Germany compiled 3D scans of 120 men and women of varying sizes, merging them into a single model that can be morphed to any shape and overlaid atop original footage.
The software, called MovieReshape, builds on existing programs that track an actor’s silhouette through a scene, mapping the body into a morphable model. Using the compiled 3D scans, the program can create realistic-looking and moving body parts to the programmer’s specifications.
