Abstract: A system and technique for displaying a document's workflow history are disclosed. The system includes a graphical user interface for displaying one or more graphical representations of events generated by an application configured to edit a document. Each of the events generated by the application may be stored in a data structure that is associated with one or more portions of the document. The data structure may also be associated with a digital image that reflects the state of the document at the time the event was generated and one or more frames of digital video captured substantially simultaneously with the generation of the event. The system may display the stored events via graphical representations in the graphical user interface that represent a portion of the total document workflow history. A user may navigate through the graphical events based on a hierarchical algorithm for clustering events.

Abstract: A computer-implemented method for traversing a video file includes populating a two-dimensional array with representative images corresponding to a portion of the video and causing the two-dimensional array to be displayed. The two-dimensional array includes a location indicator configured to traverse the two-dimensional array in a direction parallel with one dimension of the two-dimensional array in response to navigation information associated with the portion of the video. The location indicator is further configured to indicate a position in the video by highlighting one of the representative images populating the two-dimensional array. Because an end-user is provided with a large set of statically displayed representative images during navigation of a video timeline, the end-user can visually identify a desired target scene, even when traversing a the timeline relatively quickly.

Abstract: A computer-implemented method for computing skinning weights. The method includes traversing one or more paths from a first voxel included in a voxelization associated with a three-dimensional model to a second voxel included in the voxelization. The first voxel intersects a first influence included in the three-dimensional model. The second voxel intersects a target vertex associated with the three-dimensional model. The voxelization includes a set of interior voxels. The first voxel and the second voxel are included in the set of interior voxels. The method also includes identifying a first path included in the one or more paths that is associated with a first distance value related to the second voxel that indicates that the first path represents the shortest distance between the first voxel and the second voxel. The method further includes assigning a skinning weight to the target vertex based on the first distance value.

Abstract: One embodiment of the present invention is a technique for optimizing a task graph that specifies multiple tasks and the dependencies between the specified tasks. When optimizing the task graph, the optimization engine performs multiple iterations of runtime optimization operations on the task graph. At each iteration, an optimized task graph is generated based on a different task aggregation topology. The optimized task graph is then compiled and executed. Runtime statistics related to the execution are collected, and, in subsequent iterations, the task graph is further optimized based on the collected statistics. Once the optimization process is complete, the most optimal task graph topology that was identified during the process is used to generate an optimized task graph for execution.

A first object is displayed and then selected in the 3D modeling system. In response to the selecting, a transform manipulator is displayed displaying coincident with the first object. The transform manipulator includes a two-dimensional (2D) control plane object and grips located on the 2D control plane object. One of the grips is activated and used to manipulate the first object.

The tool implements may be activated and deactivated using the borders of touch-sensitive region of a multi-touch device. The tool implement can be positioned in the display area (e.g., by dragging grips of the tool) and then used (in combination with a touch gesture to perform an operation. The tool implement may be a drawing aid tool that is used to remap a user's stroke gesture to a defined stroke that is displayed.

Abstract: A technique for capturing the output of a software application, controlled by an end-user of a client computer, on a server computer. The data may be captured from a hosted application running on the server computer, an application simulating the operations of an application used by the end-user on the client computer, or from a capture stream sent by an application on the client computer. A capture engine stores the capture data on the server computer without consuming processing or memory resources of the client computer. Furthermore, the capture data is immediately available on the server computer for sharing and publication, without consuming network bandwidth or a long upload delay.

Abstract: A method, system, and computer readable storage medium/computer program product provide the ability to select an object in a three-dimensional (3D) scene. A 3D scene is displayed and consists of a first object that is displayed in the foreground and a second object that is occluded or partially occluded by the first object. An object selection option is activated. A transparency threshold value is defined for the first object. A location in the displayed 3D scene is selected. Such a location is located on a portion of the first object that occludes the second object. Based on the transparency threshold value and the location, either the first object or the second object is selected and displayed in a visually distinguishable manner.

Abstract: One embodiment of the invention sets forth a data navigation engine that generates user interface navigation elements for navigation large and expanding datasets. The user interface navigation elements may include a pivot control zoom slider for adjusting the data resolution with respect to different zoom pivot locations, an interactive ruler for consistent visual feedback and navigation of intervals of data within the dataset, a context bar for viewing the data proximate to a current view, and a multi-scale slider for repositioning the dataset within the current view. These user interface navigation elements provide the end-user with consistent control and visual feedback while navigating the dataset, independent of the size of the dataset or the portion of the dataset displayed within the current view. Therefore, large and expanding datasets can be navigated more effectively relative to prior art approaches.

The total torque M of the turbine is computed including summing, from rmin to rmax, (Cxi sin ?i+Cyi cos ?i).
