Abstract: Hybrid image projection systems and methods can superimpose image components of an input image. An input image can be divided into smaller regions and at least one parameter of each region can be determined. The input image can be decomposed based on the parameter of each region into multiple, less correlated, orthogonal or quasi-orthogonal image components. Each projector can display respective image components so that the images projected may be optically superimposed on a screen. The superposition of orthogonal or quasi-orthogonal image components can result in superposition of images in an existing multi-projector image systems being more insensitive to inter-projector image misalignment. Superimposing orthogonal or quasi-orthogonal images can be used to avoid visible image degradation, and provide more robust image quality in a multiple projector system implementation.

Abstract: Among other things, one or more techniques and/or systems are provided for defining a view direction for a texture image used to texture a geometry. That is, a geometry may represent a multi-dimensional surface of a scene, such as a city. The geometry may be textured using one or more texture images depicting the scene from various view directions. Because more than one texture image may contribute to texturing portions of the geometry, a view direction for a texture image may be selectively defined based upon a coverage metric associated with an amount of non-textured geometry pixels that are textured by the texture image along the view direction. In an example, a texture image may be defined according to a customized configuration, such as a spherical configuration, a cylindrical configuration, etc. In this way, redundant texturing of the geometry may be mitigated based upon the selectively identified view direction(s).

Abstract: A graphics virtual texturing system in which textures stored in a storage medium of a host system are divided into respective pages that are then loaded into a local memory of a graphics processing system for use. Each page of a graphics texture has an associated fade factor value that can be set by an application that is to use the texture to control the contribution that the page will be used to make to any texturing result that is generated using the texture page in question. The graphics processing system then controls the contribution of texture data from a texture page to texturing result data to be generated in accordance with the fade factor value associated with the texture page in question. This allows texture paging to be done in a more visually pleasing manner than just a binary “page-is-here”/“page-is-not-here” switch.

Abstract: A graphics virtual texturing system in which textures stored in a storage medium of a host system are divided into respective pages that are then loaded into a local memory of a graphics processing system for use. If the texture page that is required for performing a texturing operation at an originally desired level of detail (52) is not present in the local memory of the graphics processing system (53), the virtual texture lookup process loops back to try to sample the texture at an increased level of detail (55), and so on, until texture data that can be used is found in the local memory of the graphics processing system (53). This allows the texturing operation to proceed using texture data for the texel positions in question from a higher level (less detailed) mipmap in place of the originally desired texture data.

Abstract: Various embodiments of a method and apparatus for creating editable feature curves for a multi-dimensional model represented by a tessellated mesh are described. A mesh representation of a multi-dimensional model may not support intuitive modification of the model. The mesh representing the multi-dimensional model may be analyzed to extract feature curves that define the characteristics of the multi-dimensional model. Such feature curves may provide an intuitive mechanism for modifying the multi-dimensional model. The model may be modified by changing the constraints of the feature curves defining the model's characteristics. For example, a constraint may be modified to change the angle of the surface on either side of a location on a feature curve. A compressed representation of a multi-dimensional model may include the feature curves that define the shape of multi-dimensional model and a set of boundary curves that represent disjoint regions of the multi-dimensional model.

A stencil buffer is then generated that indicates pixels that are inside of the decomposed cubic Bèzier segments. The paths are then filled according to the stencil buffer to produce a filled path.

If it is found that the texels are not available in the dynamic texture memory, then the relevant texels are generated in an “on-demand” fashion and stored in the dynamic texture memory so that they can be applied to the fragment.
