摘要： A method for rendering a computer image includes, for each pixel of a plurality of N×M pixels forming a tile, determining a plurality of masks for the pixel, wherein N and M denote integers larger than 1, and wherein each mask identifies a respective subset of the pixels that are equidistant from the pixel and located at a respective distance from the pixel. The method further includes: determining an active mask for the tile, the active mask identifying active pixels of the pixels, each of the active pixels being determined as having color information; based on the active mask, identifying an empty pixel of the pixels, the empty pixel lacking color information; and determining at least a first nearest active pixel that is nearest to the empty pixel. The determining includes comparing the active mask with at least one mask of the masks for the empty pixel.

摘要： A method for generating a user-customized computer-generated animation includes receiving digital content and determining a modifiable portion of the digital content. The digital content includes a computer-generated animation. A design template is received, where the design template includes a representation of the modifiable portion of the digital content. Template image data is generated by performing image analysis on the representation of the modifiable portion of the digital content. A revised portion of the digital content is generated based on the template image data, where the revised portion is a revised version of the modifiable portion of the digital content. Updated digital content that includes a version of the computer-generated animation with the revised portion of the digital content is generated and displayed.

摘要： Systems and methods for generating an animation rig using scripted reference modules are disclosed. An embodiment includes obtaining a first reference module for generating a first node of a dependency graph, where the first reference module is a precomputed rig module corresponding to the first node, obtaining a second reference module for generating a second node of the dependency graph, where the second reference module is scripting language data executed for generating the second node, generating an association between the first node and the second node in response to an input defining the association, generating the animation rig using the first node and the second node, and providing the generated animation rig to a rig interface.

摘要： A method for determining whether a pixel of a computer-rendered image is a firefly includes: dividing a plurality of samples originating from the pixel, into first and second subsets; identifying whether the pixel is an outlier based on variance data of the first subset; identifying whether the pixel is an outlier based on variance data of the second subset. The pixel is determined as not a firefly in response to both the pixel being identified as an outlier based on the variance data of the first subset, and the pixel being identified as an outlier based on the variance data of the second subset. The pixel is determined as a firefly in response to the pixel being not identified as an outlier based on the variance data of the first (second) subset and being identified as an outlier based on the variance data of the second (first) subset.

摘要： 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.

摘要： A touch-sensitive surface for a computer animator to create or modify a computer-generated image includes processes for differentiating between click and drag operations. 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.

摘要： 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.

摘要： 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.

摘要： One exemplary process for animating hair includes receiving data representing a plurality of hairs and a plurality of objects in a timestep of a frame of animation. A first tree is populated to represent kinematic objects of the plurality of objects and a second tree is populated to represent dynamic objects of the plurality of objects based on the received data. A first elasticity preconditioner is created to represent internal elastic energy of the plurality of hairs based on the received data. Based on the first tree and the second tree, a first set of potential contacts is determined between two or more hairs of the plurality of hairs or between one or more hairs of the plurality of hairs and one or more objects of the plurality of objects. Positions of the plurality of hairs are determined based on the first set of potential contacts and the first elasticity preconditioner.

摘要： Systems and methods for rendering an image using a render setup graph are provided. The render setup graph may be used to configure and manage lighting configuration data as well as external processes used to render the computer-generated image. The render setup graph may include a dependency graph having nodes interconnected by edges along which objects and object configuration data may be passed between nodes. The nodes may be used to provide a source of objects and object configuration data, configure visual effects of an object, partition a set of objects, call external processes, perform data routing functions within the graph, and the like. In this way, the render setup graph may advantageously be used to organize configuration data and execution of processes for rendering an image.
