Abstract: One embodiment of the invention sets forth a mechanism for displaying lighting values associated with a 3-D graphics model by superimposing an overlay grid with lighting values on the 3-D graphics model. A software rendering engine computes lighting values for each frame that includes the 3-D graphics model, where each frame may have different lighting settings. An overlay grid with lighting values may be superimposed on an area defined by a light meter on the 3-D graphics model. The lighting values on the overlay grid are associated with the light meter and may vary frame-over-frame. In another embodiment, a JPEG image with a superimposed overlay grid with per-pixel lighting values covering a 3-D graphics model is generated for each frame that includes the 3-D graphics model. These JPEG images may be displayed on the screen and stored to an external memory.

The point positions of the points are used by an animation system to determine how to blend animated sequences or frames of animated sequences in order to create realistic moving animated characters and animated objects. The methods of blending are based on determining distances or deviations between corresponding points and using blending functions with varying blending windows and blending functions that can vary from point to point on the animated objects.

Abstract: Animation of computer-generated display components of user interfaces and content items is provided. An animation application or engine creates images of individual display components (e.g., bitmap images) and places those images on animation layers. Animation behaviors may be specified for the layers to indicate how the layers and associated display component images animate or behave when their properties change (e.g., a movement of an object contained on a layer), as well as, to change properties on layers in order to trigger animations (e.g., an animation that causes an object to rotate). In order to achieve high animation frame rates, the animation application may utilize three processing threads, including a user interface thread, a compositor thread and a rendering thread. Display behavior may be optimized and controlled by utilizing a declarative markup language, such as the Extensible Markup Language, for defining display behavior functionality and properties.

The method also includes retrieving data from a plurality of websites or data collections using an electronic search based on the at least one input keyword and the templates, determining which retrieved data to assemble into the set of templates, coordinating assembly of data-populated templates to form the animation, and returning the animation for playback by a user.

Abstract: Aspects include provision of a hair mesh structure that can be used for modeling, animating, simulating, and/or rendering hair and hair-like objects in the field of computer graphics. The hair mesh structure can use an ordered plurality of surface primitives, which can be represented by correspondence data, and mapping(s) of points on corresponding surface primitives. A plurality of paths can be generated based on the mappings. These paths can be used to generate hair-like geometry elements. Therefore, hair can be modeled, edited, and animated by editing surface primitives. This approach provides control of the hair shape and permits hair modeling using surface modeling processes, without direct editing of curves defining hairs themselves.
