In general, this disclosure relates to techniques for optimizing a graphics scene, such as a three-dimensional (3D) scene, by allowing application developers and/or graphics artists to identify which graphics instructions and associated graphics data (e.g., polygonal data, texture data) may be associated with identified performance issues. One example method comprises receiving mapping information from the external device, wherein the mapping information includes information to map the graphics instructions to primitive graphics data that is used to render one or more graphics images during execution of the graphics instructions, and identifying a performance issue associated with execution of at least one graphics instruction within the graphics instructions. The method further comprises using the mapping information to identify a portion of the primitive graphics data that is associated with the performance issue based upon execution of the at least one graphics instruction.

Mapping graphics instructions to associated graphics data during performance analysis

An apparatus, method, and computer program product for scaling a rendered surface. The apparatus includes a graphics processor configured to render a surface at a source resolution, wherein a scaling parameter is associated with the surface, the scaling parameter defining the source resolution and a destination resolution. The apparatus further includes a display processor configured to scale the rendered surface to the destination resolution. Preferably, the scaling parameters are EGL surface attributes.

Post-render graphics scaling

Methods and apparatus for animating images using bidirectional constraints are described.

Constraint systems and methods for manipulating non-hierarchical objects

Methods and apparatuses for scheduling and storing media creation are described. Methods and apparatuses for rendering a plurality of vector graphic objects on a display are also described.

Systems and methods for dynamic procedural texture generation management

In general, this disclosure relates to techniques for using graphics instructions and state information received from a graphics device to visually create a graphics image. Performance analysis may also be conducted to identify potential bottlenecks during instruction execution on the graphics device. One example device includes a display device and one or more processors. The one or more processors are configured to receive a plurality of graphics instructions from an external graphics device, wherein the graphics instructions are executed by the external graphics device to display a graphics image, and to receive state information from the external graphics device, wherein the state information is associated with execution of the graphics instructions on the external graphics device. The one or more processors are further configured to display, on the display device, a representation of the graphics image according to the graphics instructions and the state information.

Performance analysis during visual creation of graphics images

In one embodiment, apparatus are provided, including an embedded device simulation engine, an application run controller, and a status provider. The embedded device simulation engine is provided to simulate, on a computer platform other than a target embedded device, a 3D application authored for the target embedded device. The application run controller is provided to control the manner in which the 3D application is run in the embedded device simulation engine. The status provider is provided to provide, as the 3D application is run in the simulated environment of the embedded device simulation engine, information regarding statuses of 3D icons in the scene or scenes of the 3D application, of animations defined of the 3D icons in the 3D application, and of events occurring that affect the 3D application.

Visual debugging system for 3D user interface program

Methods and apparatus for on-the-fly identification of sub-asset modifications in a data pipeline are described.

Methods and apparatus for sub-asset modification

The present disclosure describes various techniques for displaying a visual representation of performance metrics for rendered graphics elements. One example method comprises receiving performance information provided by a graphics processing unit, wherein the performance information has been measured by the graphics processing unit in association with individual graphics elements for rendering a graphics scene, and computing values of a performance metric for the graphics elements based upon the performance information, wherein each computed value is associated with at least one of the graphics elements. The method further comprises assigning graphical identifiers to the graphics elements based upon the computed values of the performance metric for the graphics elements, wherein one of the graphical identifiers is assigned to each of the graphics elements, and displaying the graphics elements, when rendering the graphics scene, according to the graphical identifiers that are assigned to the graphics elements.

Displaying a visual representation of performance metrics for rendered graphics elements

Apparatus are provided including assets defining 3D models, including 3D icons and scenes, and animations of the 3D models. An offline optimization engine is provided to process data to be acted upon by a graphics engine of a target embedded device. A graphics engine simulator is provided to simulate, on a computer platform other than a target embedded device, select functions of a target embedded device running a graphics engine including API calls that directly calls API functions of a hardware level API of the target embedded device.
