摘要： An input stroked curve that is received by a graphics processing system can be rendering using at least two, and preferably more, rendering processes that are available for use by the system. The process or processes that are used for rendering the received stroked curve are selected based on whether the input stroked curve comprises one or more regions having a particular characteristic or characteristics, e.g. whether the input stroked curve comprises one or more self-overlapping regions. Preferably, the at least two rendering processes are each capable of correctly rendering different sets of stroked curves. Furthermore, the least two rendering process preferably differ in the processing burden that they place on the graphics processing system.

摘要： When rendering a stroked curve for display in a graphics processing system, an input stroked curve 1 defined in user space 2 is received by the system. The portion of a canonical space 5 that corresponds to the received stroked curve 1 is determined by determining the portion of a canonical curve 12 defined in the canonical space 5 that corresponds to the received stroked curve 1. Then, for each of a plurality of sampling points within one or more primitives 4 that are generated to cover the received stroked curve 1′ following its projection into surface space 3, it is determined whether a corresponding location in canonical space 5 (to the sampling point in surface space 3) is within the portion of the canonical space that corresponds to the received stroked curve, e.g. by looking up suitable information that has been stored (in advance) in one or more graphics textures. Data for rendering the received stroked curve 1 (e.g. RGBA values) is then assigned to each of the plurality of sampling points based on the determination.

摘要： A graphics processor includes a vertex shader 20 that processes input attribute values from a vertex buffer 26 to generate output vertex shaded attribute values 28 to be used by a rasteriser/fragment shader 22 of the graphics processor when processing an image for display. The system recognises when a vertex shader output attribute value to be generated from a vertex shader input attribute value by the vertex shader 20 will be a copy of the vertex shader input attribute value from which it is to be generated. In this event, the vertex shader 20 does not generate the copy vertex shader output attribute value, but the rasteriser/fragment shader 22 instead processes the corresponding vertex shader input attribute value in place of the copy vertex shader output attribute value that would otherwise have been generated by the vertex shader 20.

摘要： A graphics processing unit 2 includes a texture pipeline 6 having a first pipeline portion 18 and a second pipeline portion 20. A subject instruction within the first pipeline portion 18 is recirculated within the first pipeline portion 18 until descriptor data to be loaded from a memory 4 by that subject instruction has been cached within a shared descriptor cache 22. When the descriptor has been stored within the shared descriptor cache 22, then the subject instruction is passed to the second pipeline portion 20 where further processing operations are performed and the subject instruction recirculated until those further processing operations have completed. The descriptor data is locked within the shared descriptor cache 22 until there are no pending subject instructions within the texture pipeline 6 which required to use that descriptor data.

摘要： When encoding a set of texture data elements 30 for use in a graphics processing system, the direction along which the data values of the set of texture data elements in question exhibit the greatest variance in the color space is estimated by using one or more infinite planes 41 to divide the texture data elements in the color space. For each such plane, texture data element values on each side of the plane are added up to give respective sum points 48, 49, and the vector 50 between these two sum points determined. The direction in the data space of one of the determined vectors 50 is then used to derive endpoint color values to use when encoding the set of texture data elements.

摘要： To encode and compress a data array 30, the data array 30 is first divided into a plurality of blocks 31. A quadtree representation is then generated for each block 31 by initializing each leaf node of the quadtree to the value of the data element of the block 31 of the data array 30 that the leaf node corresponds to, and initializing each non-leaf node to the minimum value of its child nodes, and then subtracting from each node except the root node the value of its parent node. A set of data indicating the differences between respective parent and child node values in the quadtree representing the block of the data array is then generated and stored, together with a set of data representing a quadtree indicating the number of bits that have been used to signal the respective difference values.

摘要： A data array 20 to be stored is first divided into a plurality of blocks 21. Each block 21 is further sub-divided into a set of sub-blocks 22, and a set of data for each sub-block 22 is then stored in a body data buffer 30. A header data block 23 is stored for each block 21 at a predictable memory address within a header buffer 24. Each header data block contains pointer data indicating the position within the body buffer 30 where the data for the sub-blocks for the block 21 that that header data block 23 relates to is stored, and data indicating the size of the stored data for each respective sub-block 22.
