Abstract: A method for transferring graphics data includes receiving graphics data in the system memory. The graphics data may be loaded into system memory by and application from a mass storage device. One or more graphics commands associated with the graphics data may also be received. The graphics commands may also be received from the application. The graphics data in system memory is compressed in response to receipt of the one or more graphics commands before the graphics data is transferred to a discrete graphics processing unit. The one or more received graphics commands are transferred to the discrete graphics processing unit. The one or more graphics commands include an operation to copy the compressed graphics data to the discrete graphics processing unit. The compressed graphics data is copied from the system memory to memory of the graphics processing. The compressed graphics data is then decompressed by the graphics processing unit.

Abstract: An exemplary method for navigating a virtual camera in a three dimensional environment includes determining a point at an off-center location of a viewport of the virtual camera. The point corresponds to a user selection, and the virtual camera defines a field of view to view content of the three dimensional environment. The method also includes rotating the virtual camera toward the off-center location such that the point is located at a center location of the viewport. The method further includes zooming the virtual camera toward the point located at the center location of the viewport. The method also includes after the zooming the virtual camera, re-rotating the virtual camera such that the point is located at the off-center location of the viewport. The method further includes after the re-rotating, rendering the content from a projection of the viewport.
Abstract: Embodiments described herein are directed to generating a variable data image using a variable data image generator. The variable data image generator assigns a variable identifier to a specified location in a 3D scene to identify the specified location as being variable and populate the 3D scene with a component at the specified location based on the variable identifier and in response to a predefined populating rule. The predefined populating rule is applied based on an attribute of a recipient for which a static image of the 3D scene is to be generated. The component is selected and inserted at the specified location in accordance with the populating rule and with a perspective substantially matching a perspective of the specified location. The variable data generator outputs the static image of the 3D scene for the recipient, wherein the static image includes the component.
Abstract: Systems and methods are described for performing spatial and temporal compression of deformable mesh based representations of 3D character motion allowing the visualization of high-resolution 3D character animations in real time. In a number of embodiments, the deformable mesh based representation of the 3D character motion is used to automatically generate an interconnected graph based representation of the same 3D character motion. The interconnected graph based representation can include an interconnected graph that is used to drive mesh clusters during the rendering of a 3D character animation. The interconnected graph based representation provides spatial compression of the deformable mesh based representation, and further compression can be achieved by applying temporal compression processes to the time-varying behavior of the mesh clusters.

Abstract: Technologies are described herein for generating a binary transition file. Multiple animation structures may be generated in the binary transition file. The animation structures may define a sequence of three-dimensional meshes. A header portion may also be generated in the binary transition file. The header portion may define slides that are applied to the three-dimensional meshes to produce a transition between the slides. A presentation program application may be modified with the binary transition file, thereby adapting the presentation program application to provide the transition.
Abstract: A synthetic acceleration shape bound primitives composing a 3-D scene, and is defined using a group of fundamental shapes arranged to bound the primitives, and for which intersection results for group members yield an ultimate intersection testing result for the synthetic shape, using a logical operator. For example, two or more spheres are used to bound an object so that each of the spheres is larger than a minimum necessary to bound the object, and a volume defined by an intersection between the shapes defines a smaller volume in which the object is bounded. A ray is found to potentially intersect the object only if it intersects both spheres. In another example, an element may be defined by a volumetric union of component elements. Indicators can determine how groups of shapes should be interpreted. Synthetic shapes can be treated as a single element in a graph or hierarchical arrangement of acceleration elements.

Abstract: Detailed herein are approaches to enabling conditional execution of instructions in a graphics pipeline. In one embodiment, a method of conditional execution controller operation is detailed. The method involves configuring the conditional execution controller to evaluate conditional test. A pixel data packet is received into the conditional execution controller, and evaluated, with reference to the conditional test. A conditional execution flag, associated with the pixel data packet, is set, to indicate whether a conditional operation should be performed on the pixel data packet.

Abstract: A method is provided for visualizing both sides of a street based on imagery generated from panoramic street views. In particular, example methods may include directing presentation of a first panoramic view representing a first side of a street, and directing presentation of a second panoramic view representing a second side of the street. The first and second panoramic views may be presented in a street view in a perspective representation where a bottom of the first panoramic view and a bottom of the second panoramic view may be foreshortened relative to a top of each respective panoramic view, and where the bottom of each of the first panoramic view and the second panoramic view are located on either side of a representation of the street. The first panoramic view and the second panoramic view may each be formed of at least two image segments stitched together.
Abstract: Embodiments for programming a graphics pipeline, and modules within the graphics pipeline, are detailed herein. One embodiment described a method of implementing software assisted shader merging for a graphics pipeline. The method involves accessing a first shader program in memory, and generating a first shader instruction from that program. This first instruction is loaded into an instruction table at a first location, indicated by an offset register. A second shader program in memory is then accessed, and used to generate a second shader instruction. The second shader instruction is loaded into the instruction table at a second location indicated by the offset register.
