Abstract: An apparatus and method for translating fixed function state into a shader program. Fixed function state is received and stored and when a new shader program is detected the fixed function state is translated into shader program instructions. Registers specified by the program instructions are allocated for processing in the shader program. The registers may be remapped for more efficient use of the register storage space.

Abstract: A computer-implemented method for generating a constrained Delaunay triangulation for a planar domain with boundaries and internal features. The boundaries and internal features of the domain are approximated with polylines. Unconstrained Delaunay triangulation is constructed for the domain. The unconstrained Delaunay triangulation is modified to conform triangle sides to the polylines. The modified triangulation is corrected to make it a constrained Delaunay triangulation. At least one of the steps of the method is implemented using a computer.

Abstract: Disclosed are systems and methods for rule-based procedural generation of terrain in real time for a virtual world. Using the terrain editor tool, the terrain system allows defining and modifying the terrain height, color, shaders, textures, flora, and environment, for example. Additionally, generating the terrain procedurally allows for detail by changing the parameters used to create the terrain geometry. These rules can also be added and removed dynamically, leading to terrain modification in real time. In addition, resources are managed for the terrain generation system, such as memory allocation and deallocation.

The method also includes substantially aligning the surface features of the sessions and combining the aligned content.

Abstract: A techniques for coarsening a hexahedral mesh is described. The technique includes identifying a coarsening region within a hexahedral mesh to be coarsened. A boundary sheet of hexahedral elements is inserted into the hexahedral mesh around the coarsening region. A column of hexahedral elements is identified within the boundary sheet. The column of hexahedral elements is collapsed to create an extraction sheet of hexahedral elements contained within the coarsening region. Then, the extraction sheet of hexahedral elements is extracted to coarsen the hexahedral mesh.

Abstract: Techniques are provided for automatically creating style sheet animations including keyframe information. In some embodiments, a style sheet animation creation tool with a timeline-based interface is provided. By interacting with the user-interface, the user can select a point on a timeline for an animation object to add a keyframe to an animation of the animation object. In response to the user's selection of the keyframe time point, the style sheet animation creation tool displays an interactive keyframe indicator on the timeline to indicate the selected time point. With the style sheet animation creation tool, a user can generate a style sheet animation without having to author style sheet language text statements by hand.

Abstract: Embodiments of the invention relate for rendering translucent objects. According to some embodiments, the color of a pixel of a translucent object that is not directly illuminated by a light source can be determined by decaying the illumination contributed by the light source according to a predefined decay function. The decay function may be, for example, an exponential decay function. The decay function may be evaluated based on an initial illumination contributed by the light source, and a transmittance distance. In some embodiments, the initial color of the pixel is decayed instead of the illumination. Also disclosed is modifying the renderings of different regions of an object which have been rendered using different methods in order to remove sharp contrasts between these regions.

A plurality of looping motion clips may be synthesized from the motion clips, where each of the looping motion clips depicts the character object performing an equal number of motion cycles. Additionally, a starting frame of each of the plurality of looping motion clips may be synchronized so that the motion cycles in each of the plurality of looping motion clips are in phase with one another. By rendering an animation sequence using multiple passes through the looping motion space, an animation of the character object performing the motion cycles may be extended for arbitrary length of time.

Abstract: A framework for performing graphics animation and compositing operations has a layer tree for interfacing with the application and a render tree for interfacing with a render engine. Layers in the layer tree can be content, windows, views, video, images, text, media, or any other type of object for a user interface of an application. The application commits change to the state of the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, an animation is determined for animating the change in state. In determining the animation, the framework can define a set of predetermined animations based on motion, visibility, and transition. The determined animation is explicitly applied to the affected layers in the render tree. A render engine renders from the render tree into a frame buffer for display on the processing device.

Abstract: A system and method for stitching a boundary transition region of a patch produces a graphics primitive topology for the boundary transition region of the patch. A first number of vertices is computed for an inside edge of the boundary transition region using a first tessellation level of detail (LOD) of the inside edge. A second number of vertices is computed for an outside edge of the boundary transition region using a second tessellation LOD of the outside edge. A portion of the first number of vertices and the second number of vertices are merged based on a stitching pattern to produce a set of vertices for the boundary transition region. The set of vertices is stitched to produce an ordered list representing the graphics primitive topology.

Abstract: A method for correct reproduction of moving three-dimensional (3D) scenes observed by a viewer on displays showing moving three-dimensional scenes relating to video games, animated cartoons, simulators for drivers or pilots, etc. The main concept of the invention is the reproduction of a moving scene that rotates around a selected center, which is the point of the viewer's gaze fixation. Thus, all objects that are stationary with respect to each other on the illustrated scene rotate at the same angular speed but move on the screen at different linear speeds, which are inversely proportional to preselected distances from the viewer to the respective objects. Movements of objects relative to each other are presented in a coordinate system rotating with the scene. For reproduction on the display, distances to the objects, number of objects, and other selected data are entered into a conventional 3D-animation computer program.

An a priori model of the world is required, but the benefit is very accurate position and pose of the camera for every frame.
