  • Patent number: 10134167
    Abstract: Using curves to emulate soft body deformation in a computer-generated character is disclosed. A method can include accessing a reference model mapped to one or more deformation curves for the character. The reference model can include a mesh of vertices representing a soft body layer of the character. The deformation curve can include multiple sample points selected for mapping. Each mesh vertex on the model can be mapped to each sample point on the curve to establish a relationship between them for deformation. The method can also include receiving a movement of one or more sample points on the curve to a desired deformation position. The method can further include calculating primary and secondary movements of the mesh vertices on the model based on the movements of sample points. The method can move the mesh vertices as calculated to a desired deformation position and output the reference model with the moved vertices for rendering to emulate the soft body deformation of the character.

  • Publication number: 20180176174
    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.

  • Publication number: 20170316605
    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.

  • Publication number: 20170287197
    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.

  • Publication number: 20170206696
    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.
