摘要： A graphical display system comprises memory and a texture mapper. The memory stores a parametric texture map (PTM) and a non-parametric texture map (non-PTM). The texture mapper is configured to selectively apply, based on a viewing parameter of a graphical object, the PTM and the non-PTM to a pixel of the graphical object.

摘要： A system for resampling texture maps in accordance with an exemplary embodiment of the present invention comprises memory and a texture map manager. The stores a first texture map defining a first texture, and the first texture map is based on an image of an object. The texture map manager is configured to resample the first texture map such that resampling of the first texture map, by the texture map manager, compensates for a surface distortion of the object.

摘要： A texture mapping system comprises memory and a texture map manager. The memory stores a first texture map and a parametric texture map. The texture map manager is configured to combine at least a portion of the first texture map and at least a portion of the parametric texture map, and the texture map manager is configured to determine a texture map type for the first texture map and a texture map type for the parametric texture map and to perform a prioritization of the texture map portions based on the determined texture map types. The texture map manager is further configured to select, for conversion, one of the texture map portions based on the prioritization and to convert the selected texture map portion into a form corresponding to a form of the non-selected texture map portion.

摘要： The present invention provides a method for the non-uniform blending of digital representations of photographic images. The method of the present invention is a computer program. In accordance with the method of the present invention, a pair of exposure or focus bracketed photographic images are blended together to produce a single image with the best characteristics of the original images. A pixel characteristic is chosen to control the blending of the two images. Each pixel in the pair of images is analyzed, producing a single scalar value for each pixel that represents the chosen characteristic. For each image the scalar values can optionally be smoothed. Smoothing consists of averaging the scalar values for a pixel with the scalar value for all pixels within a specified neighboring region. The scalar values for all pairs of pixels are then analyzed to calculate the maximum of (scalar1_value-scalar2_value) and the minimum of (scalar1_value-scalar2_value). The values scalar1_value and scalar2_value correspond to the calculated scalar values for a pixel pair according to the chosen pixel characteristic. The pixel intensities for each pair of pixels is optionally adjusted to a common value. The common intensity value for a pair of pixels is a function of the original intensities of the pixel pair. Finally, each pixel pair is blended according to an arbitrary blending function. The blending function is a function of the independent variables: (scalar1_value-scalar2_value) for the pixel pair to be blended; max(scalar1_value-scalar2_value) for all pixel pairs in the images to be blended; min(scalar1_value-scalar2_value) for all pixel pairs in the images to be blended.

摘要： A texture mapping system comprises memory and a texture map manager. The memory stores a parametric texture map, and the parametric texture map has a plurality of texels. Each of the texels defines a variable expression that defines a luminosity parameter as a function of light direction. The texture map manager is configured to perform a rotation of a texture defined by the parametric texture map, and the texture map manager is further configured to adjust the variable expression of at least one of the texels to compensate for the rotation.
