- Face Tracking / Motion Capture – The capture of actors and tracking their movements. Actors use mocap suits that are synced to the skeleton of the model. A similar process is used to track facial movements.
- Photogrammetry – The recreation of real-life video / photography as a 3D asset (textures included)
