摘要： A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor configured to execute the instructions to perform a method that includes receiving multiple representations of one or more expressions of an object. Each of the representations includes position information attained from one or more images of the object. The method also includes producing an animation model from one or more groups of controls that respectively define each of the one or more expressions of the object as provided by the multiple representations. Each control of each group of controls has an adjustable value that defines the geometry of at least one shape of a portion of the respective expression of the object. Producing the animation model includes producing one or more corrective shapes if the animation model is incapable of accurately presenting the one or more expressions of the object as provided by the multiple representations.

摘要： A system includes a computer system capable of representing one or more animated characters. The computer system includes a blendshape manager that combines multiple blendshapes to produce the animated character. The computer system also includes an expression manager to respectively adjust one or more control parameters associated with each of the plurality of blendshapes for adjusting an expression of the animated character. The computer system also includes a corrective element manager that applies one or more corrective elements to the combined blendshapes based upon at least one of the control parameters. The one or more applied corrective elements are adjustable based upon one or more of the control parameters absent the introduction of one or more additional control parameters.

摘要： Implementations of the disclosure are directed to generating shadows in the physical world that correspond to virtual objects displayed on MR displays. In some implementations, a method includes: synchronously presenting a version of a scene on each of a MR display system and a projector display system, where during presentation: the MR display system displays a virtual object overlaid over a view of a physical environment; and a projector of the projector display system creates a shadow on a surface in the physical environment, the created shadow corresponding to the virtual object displayed by the MR display. In some implementations, the method includes: loading in a memory of the MR display system, a first version of the scene including the virtual object; and loading in a memory of the projector display system a second version of the scene including a virtual surface onto which the virtual object casts a shadow.

摘要： Some implementations of the disclosure are directed to a pipeline that enables real time engines such as gaming engines to leverage high quality simulations generated offline via film grade simulation systems. In one implementation, a method includes: obtaining simulation data and skeletal mesh data of a character, the simulation data and skeletal mesh data including the character in the same rest pose; importing the skeletal mesh data into a real-time rendering engine; and using at least the simulation data and the imported skeletal mesh data to derive from the simulation data a transformed simulation vertex cache that is usable by the real-time rendering engine during runtime to be skinned in place of the rest pose.

摘要： Performance capture systems and techniques are provided for capturing a performance of a subject and reproducing an animated performance that tracks the subject's performance. For example, systems and techniques are provided for determining control values for controlling an animation model to define features of a computer-generated representation of a subject based on the performance. A method may include obtaining input data corresponding to a pose performed by the subject, the input data including position information defining positions on a face of the subject. The method may further include obtaining an animation model for the subject that includes adjustable controls that control the animation model to define facial features of the computer-generated representation of the face, and matching one or more of the positions on the face with one or more corresponding positions on the animation model. The matching includes using an objective function to project an error onto a control space of the animation model. The method may further include determining, using the projected error and one or more constraints on the adjustable controls, one or more values for one or more of the adjustable controls. The values are configured to control the animation model to cause the computer-generated representation to perform a representation of the pose using the one or more adjustable controls.

摘要： A system includes a computing device that includes a memory for storing instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes combining, in a nonlinear manner, a first set of vertex displacements that represent the difference between a first animated expression and a neutral animated expression with a second set of vertex displacements that represent the difference between a second animated expression and the neutral animated expression. The number of vertices associated with the first set of vertex displacements of the first animated expression is equivalent to the number of vertices associated with the second set of vertex displacements of the second animated expression.

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： A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor configured to execute the instructions to perform a method that includes receiving multiple representations of an object. Each of the representations includes position information of the object and corresponds to an instance in time. For at least one of the representations, the method includes defining a contour that represents a movable silhouette of a surface feature of the object. The method also includes producing a deformable model of the surface of the object from the defined contour and from the at least one representation of the object.
