    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.

    摘要： Systems and techniques are provided for transferring changes in animation data between geometric models of a character having different resolutions. For example, systems and techniques are provided for transferring changes in geometric properties between the geometric models. A method may include obtaining a first geometric model of the character and a second geometric model of the character, the geometric models having different resolutions with different numbers of data points. The method may further include determining one or more correspondences between data points of the first geometric model and data points of the second geometric model. The correspondences include one or more data points of the first geometric model that overlap with one or more data points of the second geometric model. The method may further include determining a feature change in the first geometric model, which includes a change in a geometric property of at least one data point of the first geometric model relative to an initial geometric property of the at least one data point prior to the change. The method may further include transferring the feature change in the first geometric model to the second geometric model using the one or more correspondences, including interpolating a change in a geometric property of at least one data point of the second geometric model.

    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 and method for controlling a view of a virtual reality (VR) environment via a computing device with a touch sensitive surface are disclosed. In some examples, a user may be enabled to augment the view of the VR environment by providing finger gestures to the touch sensitive surface. In one example, the user is enabled to call up a menu in the view of the VR environment. In one example, the user is enabled to switch the view of the VR environment displayed on a device associated with another user to a new location within the VR environment. In some examples, the user may be enabled to use the computing device to control a virtual camera within the VR environment and have various information regarding one or more aspects of the virtual camera displayed in the view of the VR environment presented to the user.

    摘要： The subject matter of this specification can be embodied in, among other things, a method that includes generating intermediate values from an evaluation of one or more static expressions within shader programming code that is configured to modify an appearance of an image, compressing the intermediate values based on a determination of which intermediate values are duplicative, and storing the compressed intermediate values in a buffer accessible to an image rendering application.

    摘要： Methods and systems efficiently apply known distortion, such as of a camera and lens, to source image data to produce data of an output image with the distortion. In an embodiment, an output image field is segmented into regions so that on each segment the distortion function is approximately linear, and segmentation data is stored in a quadtree. The distortion function is applied to the segmented image field to produce a segmented rendered distortion image (SRDI) and a corresponding look-up table. To distort a source image, a location in the output image field is selected, and the uniquely colored segment at the same location in the SRDI is found. The look-up table provides the local linear inverse of the distortion function, which is applied to determine from where in the source image to take image texture data for the distorted output image.

    摘要： A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes producing an animation model from one or more representations of an object provided from a deformable likeness of the object. The one or more representations are based upon position information from a collection of images of the object captured by at least one camera. The method also includes refining the animation model to produce representations that substantially match the one or more representations provided by the deformable likeness of the object. Refining the animation model is based upon the position information from the collection of images of the object and one or more constraints.
