A tinting material may be generated and applied to the backdrop of an application presented on a user interface. The user interface is presented on a display and includes a background. The background comprises a first color, which includes a luminosity value, a hue value, and a saturation value. A tint color, having a luminosity value, a hue value, a saturation value, and an opacity value, is received. The luminosity value of the first color is modified to generate a second color, and the hue value and saturation value of the generated second color are modified to generate a third color. A tinting material color is generated that includes the modified luminosity value of the second color, the modified hue value of the third color, and the modified saturation value of the third color, and an application is presented on the user interface that includes the tinting material color.

Tinting material on an interface

Object sets are often organized and traversed in a hierarchical manner according to ownership, wherein a subset of contained objects are processed before or after a containing object that contains the contained objects. Such object sets may also be presented as a scene, which may involve traversing the object set in a drawing order, such as a descending distance order that renders objects in a back-to-front manner. It may be difficult to reconcile these distinct traversal techniques, particularly if different portions of the object set utilize a different traversal order. Presented herein are hybrid traversal techniques in which a selected subset of related objects is identified and traversed in a drawing order, and the remainder of the object set is traversed in an ownership order, in furtherance of various tasks that involve hybrid traversal orders and/or to facilitate the traversal of different types of object subsets within the object set.

Hybrid traversal of object sets

Virtual environments may be presented to a user with an inclusion of one or more applications, but many such techniques for integrating the applications with the virtual environment may exhibit disadvantages. For example, a two-dimensional 'flat' rendering of the application may require a loss of visual depth, and/or may appear inconsistent; an immersive presentation that is mutually exclusive with the presentation of the virtual environment may achieve very limited integration; and a holographic presentation may appear incongruous. Such techniques may also increase presentation latency, with noticeable and significant consequences. Instead, the virtual environment may define an application region, and may notify the application of the application region and a perspective of the user within the virtual environment. The application may present an application view that reflects the perspective of the user, and the virtual environment may present the application view within the application region of the virtual environment.

Presenting applications within virtual environments

A scene may be rendered as objects that are lit by various light sources. A scene designer may arrange the scene to create particular lighting effects when viewed from an initial perspective, such as gloss, translucency, and iridescence, and may choose lighting effects to create a desired aesthetic tone and/or highlighting within the scene. However, rendering the scene from a different perspective may alter the lighting effects (e.g., losing or misplacing desired lighting effects, and/or creating new and undesirable lighting effects, such as glare). Instead, when the scene is rendered from the initial perspective, the lighting effects created therein may be stored with the scene representation of the scene. A second rendering of the scene from a different perspective may reapply the stored lighting effects to the lit objects, thereby maintaining the lighting effects and the intent of the designer in the presentation of the scene from a different perspective.

Preserving scene lighting effects across viewing perspectives

Systems and methods are provided for improved filtering and correcting of glyphs on a GPU. The computational intensity required for filtering and/or rendering can be reduced by pre-calculating some or all of the calculations needed for converting coverage data into corrected pixel values. Additional efficiencies may be realized in some embodiments by transferring data from a CPU to a GPU in an improved format. The improvements can be realized in a variety of graphics formats.

Lookup tables for text rendering

A system, a method and computer-readable media for rendering text with a graphics processing unit (GPU). The system, method, and media includes a GPU that may be configured to receive a plurality of compressed glyph bitmap and create a plurality of glyph textures from the bitmap. The GPU may be further configured to pack a plurality of rows of data from a glyph bitmap into a single row of a glyph texture. The GPU may be also be configured to merge the plurality of glyph textures into a merged texture to identify overlapping rows of color. Additionally, the GPU maybe configured to filter the merged texture to create a grayscale texture containing a plurality of merged glyphs and rendering the grayscale texture to display the plurality of merged glyphs.

Color packing glyph textures with a processor

Systems and methods are disclosed for providing texture tiling. The disclosed systems and methods may include copying a source image into a texture of a size the same or larger than the source image. Furthermore, the disclosed systems and methods may include displacing texture coordinates corresponding to the texture into a desired range. A displacement map may be used in displacing the texture coordinates. Moreover, the disclosed systems and methods may include rendering, within the desired range, an output image corresponding to the texture coordinates associated with the texture.

Methods and systems for providing texture tiling and mirroring

Systems and methods are provided for providing anti-aliasing by introducing a falloff area around a graphics object to be rendered. The falloff area is shaded, using Gouraud shading or texture mapping to reduce the aliasing effects of the graphics object. The outside edge of the falloff area is set to be fully transparent, and the inside edge to an opacity matching the outer edge of the graphics object being rendered. To counteract bloating effects, the graphics object is shrunk by half the width of the falloff area. While the width of the falloff area may vary, generally, the width of the falloff area stays constant. In one embodiment, this width corresponds to the edge or diagonal of the square area mapped to each pixel.

Hardware accelerated anti-aliased primitives using alpha gradients

Aspects of the subject matter described herein relate to applying effects to a target via compositing rendering layers. In aspects, an intent is determined and a area of a target copied to a surface based on the intent. Then, rendering may continue to the target without changing to another target. Later, the surface is composited back to the target to apply an effect to the target.

Compositing rendering layers

A method and system for controlling gamut mapping algorithm parameters and exposing those parameters as user interface elements to allow users to interactively control the gamut mapping algorithm parameters is provided. A request to modify a user interface is received and a modified gamut mapping algorithm parameter element is loaded into the user interface in response. The request to modify can be a request to modify a pre-existing gamut mapping algorithm parameter element or a format of a corresponding gamut mapping algorithm parameter. User specified requests to adjust gamut mapping algorithm parameter elements are received and color management operations are adjusted in response. A three dimensional representation of a device color gamut can be displayed and modified by a user, and an input image that is being processed by the color management operations is displayed and modified dynamically in response to user specific adjustments.
