Abstract: A system and method provides a computer-implemented messaging service. Users subscribe to message channels. A message queue buffers messages to a router. The router determines whether characteristics of a first message match criteria specified in subscription requests, and may route the first message to one or more sending agents based on modes of communication specified in the subscription service requests. The sending agent(s) generate a second message formatted for the specified modes of communication based on the first message. Message load balancing, message queuing, message routing, and message sending services may all be independently scaled to adjust for demand.

Abstract: A method for generating stereoscopic images includes obtaining image data comprising a plurality of sample points. A direction, a color value, and a depth value are associated with each sample point. The directions and depth values are relative to a common origin. A mesh is generated by displacing the sample points from the origin. The sample points are displaced in the associated directions by distances representative of the corresponding depth values. The image data is mapped to the mesh such that the color values associated with the sample points are mapped to the mesh at the corresponding directions. A first image of the mesh is generated from a first perspective, and a second image of the mesh is generated from a second perspective. The first and second images of the mesh may be caused to be displayed to provide an illusion of depth.

Abstract: A method of scheduling and performing computations for generating an interactive computer-generated animation on behalf of a client device to achieve a desired quality of service includes generating a computational configuration of computations that, when performed, produce the computer-generated animation with the desired quality of service. The configuration includes an identification of a first computation that outputs first data, a first start time for the first computation, and a first end time, where the first computation is to end before the first end time. The configuration also includes an identification of a second computation that depends on the first data, and a second start time for the second computation. The first computation is performed in response to an occurrence of the first start time and the second computation is performed in response to an occurrence of the second start time.

Abstract: Computer animation tools for viewing, in multiple contexts, the effect of changes to a computer animation are disclosed. An artist configures multiple visual displays in the user interface of a computer animation system. A visual display shows one or more frames of computer animation. An artist configures a visual display to reflect a specific context. For example, the artist may assign a particular virtual viewpoint of a scene to a particular visual display. Once visual displays are configured, the artist changes a configuration of the computer animation. For example, the artist may change the lighting parameters of a scene. In response, the visual displays show the visual effects of the configuration (e.g., lighting parameters) change under corresponding contexts (e.g., different virtual camera viewpoints). Using multiple visual displays, which may be displayed side-by-side, an artist can view the effects of her configuration changes in the various contexts.

Abstract: Systems and processes providing a tool for visualizing parallel dependency graph evaluation in computer animation are provided. Runtime evaluation data of a parallel dependency graph may be collected, including the start time and stop time for each node in the graph. The visualization tool may process the data to generate performance visualizations as well as other analysis features. Performance visualizations may illustrate the level of concurrency over time during parallel dependency graph evaluation. Performance visualizations may be generated by graphing node blocks according to node start time and stop time as well as the level of concurrency at a given time to illustrate parallelism. Performance visualizations may enable character technical directors, character riggers, programmers, and other users to evaluate how well parallelism is expressed in parallel dependency graphs in computer animation.

Abstract: Systems and methods for automatically animating a character based on an existing corpus of animation are described. The character may be from a previously produced feature animated film, and the data used for training may be the data used to animate the character in the film. A low-dimensional embedding for subsets of the existing animation corresponding to different semantic labels may be learned by mapping high-dimensional rig control parameters to a latent space. A particle model may be used to move within the latent space, thereby generating novel animations corresponding to the space's semantic label, such as a pose. Bridges may link a first pose of a first model within the latent space that is similar to a second pose of a second model of the space. Animations corresponding to transitions between semantic labels may be generated by creating animation paths that traverse a bridge from one model into another.

The included processes also beneficially reduce input errors. When a touch object (e.g., finger or stylus) touches the drawing table, information regarding the duration of the touch and the movement of the touch are used to determine whether the touch input represents a (graphical user interface) click or a drag operation.

Abstract: An electronic device with a display screen provides drawing directions to guide a user to create artwork on a physical medium. The electronic device displays a first drawing direction for drawing a portion of a subject on a physical medium, and prompts a user for a user input indicating completion of the first drawing direction by the user. Upon receiving the prompted user input, the electronic device displays a second drawing direction for drawing another portion of the subject on the physical medium. The subject may be based on a computer-animated movie title. The first drawing direction may include a representation of a virtual host, which is also based on a computer-animated character from a computer-animated movie title.

In this way, the render setup graph may advantageously be used to organize configuration data and execution of processes for rendering an image.

Abstract: A computer-implemented method determining a user-defined stereo effect for a computer-generated scene. A set of bounded-parallax constraints including a near-parallax value and a far-parallax value is obtained. A stereo-volume value is obtained, wherein the stereo-volume value represents a percentage of parallax. A stereo-shift value is also obtained, wherein the stereo-shift value represents a distance across one of: an area associated with a camera sensor of a pair of stereoscopic cameras adapted to film the computer-generated scene; and a screen adapted to depict a stereoscopic image of the computer-generated scene. A creative near-parallax value is calculated based on the stereo-shift value, the stereo-volume, and the near-parallax value. A creative far-parallax value is also calculated based on the stereo-shift value and the product of the stereo-volume and the far-parallax value.
