摘要： Systems and methods for manipulating a virtual three-dimensional (3D) object in a virtual 3D space are provided. A representation of the 3D object is displayed on a display. A non-hemispherical arcball having a surface is determined. The non-hemispherical arcball is associated with the representation of the 3D object. A pointing device is detected at a first position and at a second position. The first position of the pointing device is translated onto a first location on the surface of the non-hemispherical arcball. The second position of the pointing device is translated onto a second location on the surface of the non-hemispherical arcball. A rotation of the representation of the 3D object is displayed on the display, the rotation based on a path of travel between the first location and the second location along the surface of the non-hemispherical arcball.

摘要： A rail manipulator indicates the possible range(s) of movement of a part of a computer-generated character in a computer animation system. The rail manipulator obtains a model of the computer-generated character. The model may be a skeleton structure of bones connected at joints. The interconnected bones may constrain the movements of one another. When an artist selects one of the bones for movement, the rail manipulator determines the range of movement of the selected bone. The determination may be based on the position and/or the ranges of movements of other bones in the skeleton structure. The range of movement is displayed on-screen to the artist, together with the computer-generated character. In this way, the rail manipulator directly communicates to the artist the degree to which a portion of the computer-generated character can be moved, in response to the artist's selection of the portion of the computer-generated character.

摘要： Systems and processes are described below relating to evaluating a dependency graph having one or more temporally dependent variables. The temporally dependent variables may include variables that may be used to evaluate the dependency graph at a frame other than that at which the temporally dependent variable was evaluated. One example process may include tracking the temporal dirty state for each temporally dependent variable using a temporal dependency list. This list may be used to determine which frames, if any, should be reevaluated when a request to evaluate a dependency graph for a particular frame is received. This advantageously reduces the amount of time and computing resources needed to reevaluate a dependency graph.

摘要： Search-based matching for multiple parameter sets in computer animation is disclosed. The search-based matching method can include receiving a selection of a first set of joint parameters in a first model to match to a second set of joint parameters in a second model, currently in operation, for an appendage of a computer-generated object. The method can also adjust the selected first set of joint parameters to match the second set of joint parameters. The method can further compare the adjusted first set of joint parameters to the second set of joint parameters. Based on the comparison, the method can switch from the second model to the first model and replace the second set of joint parameters with the adjusted first set of joint parameters. The method can then output the replacement first set of joint parameters for rendering the appendage of the object.

摘要： Systems and processes are described below relating to evaluating a dependency graph to render three-dimensional (3D) graphics using constraints. Two virtual 3D objects are accessed in a virtual 3D space. A constraint relationship request is received, which identifies the first object as a parent and the second object as a child. The technique verifies whether the graphs of the objects are compatible for being constrained to one another. The first object is evaluated to determine its translation, rotation, and scale. The second object is similarly evaluated based on the translation, rotation, and scale of the first object. An image is rendered depicting at least a portion of the first virtual 3D object and at least a portion of the second virtual 3D object.

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.
