摘要： Methods and primitive block generators for generating untransformed primitive blocks in a graphics processing system. The primitive block generators comprise a data store for storing a current untransformed primitive block to which transformed primitives can be associated The methods comprise: determining one or more distance metrics that indicate a distance between a spatial position of a set of one or more transformed primitives in a rendering space and a spatial position of the transformed primitives associated with the current untransformed primitive block in the rendering space; determining a fullness metric based on at least one of: (i) a number of transformed primitives associated with the current untransformed primitive block compared to a maximum number of primitives, and (ii) where each transformed primitive is defined by one or more transformed vertices, a number of transformed vertices associated with the current untransformed primitive block compared to a maximum number of vertices; dynamically selecting a set of one or more distance thresholds based on the fullness metric, the set of one or more distance thresholds comprising a distance threshold for each of the one or more distance metrics; determining whether to associate the set of one or more transformed primitives with the current untransformed primitive block based on a comparison of each of the one or more distance metrics to the corresponding distance threshold of the set of one or more distance thresholds; and in response to determining that the set of one or more transformed primitives is to be associated with the current untransformed primitive block, associating the set of one or more transformed primitives with the current untransformed primitive block by adding information to the current untransformed primitive block identifying untransformed geometry data from which the set of one or more transformed primitives was generated.

摘要： There is disclosed a method of rendering a frame showing a scene formed by primitives in a tile-based graphics processing system. The method comprises a geometry processing phase, comprising the step of tiling the primitives in the scene, to determine which primitives at least partially overlap which tiles of the frame to be rendered. The method also comprises a rendering phase comprising a step of obtaining a fragment density map defining one or more texels, each texel corresponding to an area of the frame to be rendered and having an associated fragment size, wherein for each of the texels, the texel's height is an integer multiple of a native tile height used in the tile-based graphics processing system and the texel's width is an integer multiple of a native tile width used in the tile-based graphics processing system. The rendering phase also comprises, for each tile to be rendered: determining from the fragment density map a fragment size to be used to render the tile, performing sampling using the determined fragment size and performing fragment shading using the determined fragment size.

摘要： A system and method for rendering a digital image in order to recreate a physical instant analog print developing experience for the digital image is provided. The method includes, for example, receiving a digital image at a first computing device from a source over a network, the digital image including characteristic(s) (e.g., contrast, saturation, etc.), each characteristic having a received level; detecting whether the digital image is to be gradually rendered over a predetermined time in order to provide a user with a simulated experience of instant analog print developing; and based on the detecting, gradually rendering the digital image on a display associated with the first computing device over the predetermined time, the gradually rendering including increasing a level of the characteristic(s) until the level reaches the corresponding received level.

摘要： A method and a compression unit are provided for compressing, into a block of compressed data, a block of sub-primitive presence indications for use in a rendering system. The block of sub-primitive presence indications comprises a plurality of sub-blocks of sub-primitive presence indications. A plurality of candidates for combinations of presence indications are identified. For each of the sub-blocks in the block of sub-primitive presence indications: one of the candidates to be used to represent the sub-block is selected, and an index to indicate the selected candidate is stored in the block of compressed data.
