Abstract: A method for determining a depth ordering between two planes in a 3D workspace of an application is provided. The method includes projecting vectors from a reference position through points of interest on the planes, determining corresponding points on the other plane, determining a number of points of interest on a first plane having a depth lower than its corresponding point and a number of points of interest on a second plane having a depth lower than its corresponding point, and setting the depth ordering based on these numbers. A method for displaying interconnects between nodes of a tree displayed in an application is provided. A node represents a multimedia item or a function and an interconnect represents data passed between two nodes. The method includes displaying an interconnect in the tree having an appearance indicating at least one characteristic of the data being passed between two nodes.

Abstract: Some embodiments of the invention provide a user interface of editing video through a multi-stage editing process. The user interface selects a particular stage in the editing process. A particular editing operation is performed on a set of video images during the particular stage. After the selection of the particular stage, the user interface uses a background rendering process to render the result of the particular editing operation on the particular set of video images. The background rendering process is a process that the user interface performs separately from the multi-stage video editing process, so that a user may continue editing the video sequence while the rendering occurs. Some embodiments provide a preview of the rendering process in a preview window. Some of these embodiments update the preview in real time. In some embodiments, the rendering occurs to a temporary location and then stores to a persistent storage.

Abstract: Some embodiments provide a method for locking in a mathematical relationship between a set of at least two parameters in a computer program. The method selects a first parameter. The method defines a mathematical relationship that ties the value of the first parameter to the value of a second parameter. In some embodiments, the mathematical relationship can be a mathematical function, a Boolean function, or a lookup table. The relationship could be directly entered by the user, or the computer program itself could derive it from the user's actions. In some embodiments, the first parameter can be locked to the mathematical relationship. The lock prevents the value of that parameter from being changed, except by changing the value of the second parameter. Some embodiments implement this method by using a GUI with an intuitive set of controls.

Abstract: An efficient way to perform rendering operations in an image processing environment includes a warping engine having a warping module and a domain of definition (DOD) module. When an object is warped, a new DOD for the image is determined by the warping engine by comparing the location of certain pixels in the warped image with their corresponding locations in the original image. By maintaining a DOD for the warped images, only that portion of the DOD that intersects with a region of interest is computed, thus resulting in optimized performance.
