摘要： The system includes a shape buffer manager configured to store coverage data in the shape buffer. The coverage data indicates whether each mask pixel is a covered pixel or an uncovered pixel. A mask pixel is a covered pixel when a shape to be rendered on a screen covers the mask pixel such that one or more coverage criteria is satisfied and is an uncovered pixel when the shape does not cover the mask pixel such that the one or more coverage criteria are satisfied. A bounds primitive rasterizer is configured to rasterize a bounds primitive that bounds the shape. The bounds primitive is rasterized into primitive pixels that each corresponds to one of the mask pixels. A pixel screener is configured to employ the coverage data from the shape buffer to screen the primitive pixels into retained pixels and discarded pixels. The retained pixels each corresponds to a mask pixel that the coverage data indicates is a covered pixel and the discarded pixels each correspond to a mask pixels that the coverage data indicates is an uncovered pixel. The system also includes an attribute generator configured to generate pixel attributes for the retained primitive pixels and also configured not to generate pixel attributes for the discarded primitive pixels.

摘要： Techniques for supporting both 2-D and 3-D graphics are described. A graphics processing unit (GPU) may perform 3-D graphics processing in accordance with a 3-D graphics pipeline to render 3-D images and may also perform 2-D graphics processing in accordance with a 2-D graphics pipeline to render 2-D images. Each stage of the 2-D graphics pipeline may be mapped to at least one stage of the 3-D graphics pipeline. For example, a clipping, masking and scissoring stage in 2-D graphics may be mapped to a depth test stage in 3-D graphics. Coverage values for pixels within paths in 2-D graphics may be determined using rasterization and depth test stages in 3-D graphics. A paint generation stage and an image interpolation stage in 2-D graphics may be mapped to a fragment shader stage in 3-D graphics. A blending stage in 2-D graphics may be mapped to a blending stage in 3-D graphics.

摘要： A first copy of an object is rendered using a texture sample selected from a texture image. This texture sample is selected from the texture image according to a first set of texture coordinates. The rendered object is stored in a frame buffer. Next, a second copy of the object is rendered using a second texture sample selected from the texture image. The second texture sample is selected from the texture image according to a second set of texture coordinates calculated in accordance with the first set of texture coordinates and one or more Jitter factors. The second set of calculated texture coordinates is displaced from the first set of texture coordinates along an axis of anisotropy. This second rendered copy of the object is then blended with the first rendered copy of the object to produce an object with anisotropic filtering. In embodiments of the invention, more than two copies of the object are rendered and blended together to form an object with anisotropic filtering.

摘要： Scissoring for any number of scissoring regions is performed in a sequential order by drawing one scissoring region at a time on a drawing surface and updating scissor values for pixels within each scissoring region. A scissor value for a pixel may indicate the number of scissoring regions covering the pixel and may be incremented for each scissoring region covering the pixel. A scissor value for a pixel may also be a bitmap, and a bit for a scissoring region may be set to one if the pixel is within the scissoring region. Pixels within a region of interest are passed and rendered, and pixels outside of the region are discarded. This region may be defined by a reference value, which may be set to (a) one for the union of all scissoring regions, for a scissoring UNION operation, or (b) larger than one for the intersection of multiple (e.g., all) scissoring regions, for a scissoring AND operation.

摘要： A variable number of textures are blended together using a single texture as a mask. At least four textures are received. Masks are extracted from one of the received textures and used to blend together the remaining textures. In an embodiment, N masks are extracted from a single texture and used to blend N+1 additional textures. In this embodiment, two of the N+1 textures are initially blended together in accordance with one of the N masks to form an image. Another texture of the N+1 textures is then blended with the image in accordance with another one of the N masks. This iterative blending process continues until all of the N+1 textures have been blended together. In another embodiment, N textures are blended together by multiplying each of the N textures by one of the N masks and adding together the results of the N multiplications.
