摘      要：The Digital Emily Project uses advanced face scanning, character rigging, performance capture, and compositing to achieve one of the world s first photorealistic digital facial performances. The project scanned the geometry and reflectance of actress Emily O Brien s face in 33 poses, showing different emotions, gaze directions, and lip formations in a light stage. These high-resolution scans—accurate to skin pores and fine wrinkles—became the basis for building a blendshape-based facial-animation rig whose expressions closely matched the scans. The blendshape rig drove displacement maps to add dynamic surface detail. A video-based facial animation system animated the face according to the performance in a reference video, and the digital face was tracked onto the video s motion and rendered under the same illumination. The result was a realistic 3D digital facial performance credited as one of the first to cross the uncanny valley between animated and fully human performances.
