摘要： A method of transferring a facial expression from a subject to a computer generated character that includes receiving a plate with an image of the subject's facial expression, a three-dimensional parameterized deformable model of the subject's face where different facial expressions of the subject can be obtained by varying values of the model parameters, a model of a camera rig used to capture the plate, and a virtual lighting model that estimates lighting conditions when the image on the plate was captured. The method can solve for the facial expression in the plate by executing a deformation solver to solve for at least some parameters of the deformable model with a differentiable renderer and shape from shading techniques, using, as inputs, the three-dimensional parameterized deformable model, the model of the camera rig and the virtual lighting model over a series of iterations to infer geometry of the facial expression and generate a final facial mesh using the set of parameter values of the deformable model which result in a facial expression that closely matches the expression of the subject in the plate.

摘要： A method of transferring a facial expression from a subject to a computer generated character that includes: receiving a plate with an image of the subject's facial expression and an estimate of intrinsic parameters of a camera used to film the plate; generating a three-dimensional parameterized deformable model of the subject's face where different facial expressions of the subject can be obtained by varying values of the model parameters; solving for the facial expression in the plate by executing a deformation solver to solve for at least some parameters of the deformable model with a differentiable renderer and shape-from-shading techniques, using as inputs, the three-dimensional parameterized deformable model, estimated intrinsic camera parameters, estimated lighting conditions and albedo estimates over a series of iterations to infer geometry of the facial expression and generate an intermediate facial; generating, from the intermediate facial mesh, refined albedo estimates for the deformable model; and solving for the facial expression in the plate by executing the deformation solver using the intermediate facial mesh, the estimated intrinsic camera parameters, the estimated lighting conditions and the refined albedo estimates as inputs over a series of iterations to infer geometry of the facial expression and generate a final facial mesh using the set of parameter values of the deformable model which result in a facial expression that more closely matches the expression of the subject in the plate than does the intermediate facial mesh.

摘要： Some implementations of the disclosure are directed to techniques for facial reconstruction from a sparse set of facial markers. In one implementation, a method comprises: obtaining data comprising a captured facial performance of a subject with a plurality of facial markers; determining a three-dimensional (3D) bundle corresponding to each of the plurality of facial markers of the captured facial performance; using at least the determined 3D bundles to retrieve, from a facial dataset comprising a plurality of facial shapes of the subject, a local geometric shape corresponding to each of the plurality of the facial markers; and merging the retrieved local geometric shapes to create a facial reconstruction of the subject for the captured facial performance.

摘要： A method may include capturing a first image of a physical environment using a mobile device. The mobile device may include a physical camera and a display. The method may also include receiving a second image from a content provider system. The second image may be generated by the content provider system by rendering a view from a virtual camera in a virtual environment. The virtual environment may represent at least a portion of the physical environment. A location of the virtual camera in the virtual environment may correspond to a location of the physical camera in the physical environment. The second image may include a view of a computer-generated object. The method may additionally include generating a third image by compositing the first image and the second image, and causing the third image to be displayed on the display of the mobile device.

摘要： Systems and techniques are provided for switching between different modes of a media content item. A media content item may include a movie that has different modes, such as a cinematic mode and an interactive mode. For example, a movie may be presented in a cinematic mode that does not allow certain user interactions with the movie. The movie may be switched to an interactive mode during any point of the movie, allowing a viewer to interact with various aspects of the movie. The movie may be displayed using different formats and resolutions depending on which mode the movie is being presented.

摘要： Systems, devices, and methods are disclosed for UV packing. The system includes a non-transitory computer-readable medium operatively coupled to processors. The non-transitory computer-readable medium stores instructions that, when executed, cause the processors to perform a number of operations. One operation is to present a packing map using a graphical user interface including a selection tool. Another operation is to present a first set of one or more target objects using the graphical user interface. Individual ones of the first set include one or more features. One operation is to receive a first user input. Another operation is to, based on the first user input and the one or more features corresponding to the individual ones of the first set, pack the first set into a packing map.

摘要： Views of a virtual environment can be displayed on mobile devices in a real-world environment simultaneously for multiple users. The users can operate selections devices in the real-world environment that interact with objects in the virtual environment. Virtual characters and objects can be moved and manipulated using selection shapes. A graphical interface can be instantiated and rendered as part of the virtual environment. Virtual cameras and screens can also be instantiated to created storyboards, backdrops, and animated sequences of the virtual environment. These immersive experiences with the virtual environment can be used to generate content for users and for feature films.
