摘要： A method of facilitating an interactive rendering of a computer image at a remote computer includes: at a first time, obtaining first information of the image, including pixel information of the image at the first time; and, at a second time after the first time, obtaining second information of the image including pixel information of the image at the second time. Delta pixel information is generated by comparing the pixel information of the first information with the pixel information of the second information, to include one or more portions of the pixel information of the second information updated since the first information was obtained, and to exclude one or more portions of the pixel information of the second information unchanged since the first information was obtained. The method further includes: transmitting the delta pixel information in a lossless format to a front-end client to enable reconstruction of the second information.

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 method for composing a scene using a data module includes: receiving, from a user, an instruction to instantiate the data module to produce at least a first instance of the data module in a second data module; receiving, from the user, a first override for modifying the first instance of the data module; receiving, from the user, a second override for modifying the data module; identifying a conflict introduced by the first override or the second override; configuring a display interface to display an indication informing the user of the identified conflict; configuring the display interface to display one or more options for resolving the identified conflict; receiving, from the user, a selection of an option of the one or more options; and in response to the selection of the option, resolving the identified conflict by deleting the first override or the second override.

摘要： Systems and methods deforming a mesh of a target object in real-time in response to a collision with a collision object are disclosed. An embodiment includes determining an inwardly deformed position of a first vertex of the mesh based on an intersection point of a boundary associated with the collision object with a ray, the ray connecting a point of an internal element of the target object with a reference position of the first vertex, wherein the inwardly deformed position of the first vertex corresponds to a first deformation magnitude of the first vertex from the reference position to the inwardly deformed position.

摘要： Systems and methods for dynamic contour volume deformation are disclosed. An embodiment includes applying a deformation to a point of a volumetric mesh, wherein a plurality of tessellations of the volumetric mesh are identified and wherein each tessellation is a tetrahedral mesh, identifying a deformation point associated with a first polyhedron of the volumetric mesh, determining a barycentric coordinate representation of the deformation point with respect to each tetrahedron of the plurality of tessellations, determining, for each tessellation of the first polyhedron, weight values with respect to the deformation point for vertices of each tetrahedron which correspond to natural vertices of each tetrahedron, and determining, based on the determined weight values, a new position of the identified deformation point represented as a weighted sum determined from the barycentric coordinate representations.

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.
