20140267306 | CONTENT AWARE TEXTURE MAPPING ON DEFORMABLE SURFACES - A method is disclosed for reducing distortions introduced by deformation of a surface with an existing parameterization. In one embodiment, the distortions are reduced over a user-specified convex region in texture space ensuring optimization is locally contained in areas of interest. A distortion minimization algorithm is presented that is guided by a user-supplied rigidity map of the specified region. In one embodiment, non-linear optimization is used to calculate the axis-aligned deformation of a non-uniform grid specified over the region's parameter space, so that when the space is remapped from the original to the deformed grid, the distortion of the rigid features is minimized. Since grids require minimal storage and the remapping from one grid to another entails minimal cost, grids can be precalculated for animation sequences and used for real-time texture space remapping that minimizes distortions on specified rigid features. | 09-18-2014 |

In a second aspect, two or more separate areas can be processed in parallel by deriving control data for the two separate areas at a time. This improves processing time. To avoid fetching data for both areas, that is actually only applicable to one area, encoding is used in the control data. In a third aspect, object data can be stored on one or across two memory pages, and the control data includes one memory page address in the former case and two memory page addresses in the latter case. This improves memory usage. In a fourth aspect, object data can be stored across two non-contiguous memory pages, by using a look-up table with contiguous portions allocated for each object's object data. This also improves memory usage. In a fifth aspect, when partial rendering is used, and partial depth data is stored and subsequently updated, the depth data can be stored across two memory pages using link portions in the memory pages to either indicate the end of data storage or point to the next memory page.

A rendering space is divided into a plurality of regions which may for example be a plurality of tiles or a plurality of areas into which one or more tiles are divided. Depth thresholds for the regions, which are used to identify hidden objects for culling, are updated when an object entirely covers a region and in dependence on a comparison between a depth value for the object and the depth threshold for the region. For example, if the depth threshold is a maximum depth threshold, the depth threshold may be updated if an object entirely covers the tile and the maximum depth value of the object is less than the maximum depth threshold. | 09-18-2014 |

The data in the data block is analysed to determine a compression grouping scheme according to which data segments of the vertices are grouped together into segment blocks for compression. The analysis of the data determines a compression grouping scheme which is suited to the distribution of the data in the data block, to thereby improve the compression ratio which can be achieved when compressing the data block. | 12-04-2014 |
20150228049 | Processing of Primitive Blocks in Parallel Tiling Engine Pipes - A tiling unit is arranged to process a sequence of primitive blocks using multiple parallel tiling engine pipes. Each tiling engine pipe processes a respective primitive block, and determines priorities for regions of the respective primitive block based on whether the primitive block overlaps with any of the other primitive blocks currently being processed in the parallel tiling engine pipes. Each tiling engine pipe processes the regions of its primitive block in a tile-order based on the priorities of the regions. The submission order of the primitives should be maintained when primitive identifiers are written into display lists. Therefore, the priority of a region of a first primitive block is increased (or decreased) if it overlaps with another primitive block which has a higher (or lower) sequence number and which is currently being processed in another tiling engine pipe. This reduces the time that the tiling engine pipes are idle. | 08-13-2015 |
20150348306 | ALLOCATION OF PRIMITIVES TO PRIMITIVE BLOCKS - An application sends primitives to a graphics processing system so that an image of a 3D scene can be rendered. The primitives are placed into primitive blocks for storage and retrieval from a parameter memory. Rather than simply placing the first primitives into a primitive block until the primitive block is full and then placing further primitives into the next primitive block, multiple primitive blocks can be “open” such that a primitive block allocation module can allocate primitives to one of the open primitive blocks to thereby sort the primitives into primitive blocks according to their spatial positions. By grouping primitives together into primitive blocks in accordance with their spatial positions, the performance of a rasterization module can be improved. For example, in a tile-based rendering system this may mean that fewer primitive blocks need to be fetched by a hidden surface removal module in order to process a tile. | 12-03-2015 |
20150363968 | ASSIGNING PRIMITIVES TO TILES IN A GRAPHICS PROCESSING SYSTEM - A tiling unit assigning primitives to tiles in a graphics processing system which has a rendering space subdivided into a plurality of tiles. Each tile can comprise one or more polygonal region. Mesh logic of the tiling unit can determine that a plurality of primitives form a mesh and can determine whether the mesh entirely covers a region. If the mesh entirely covers the region then a depth threshold for the region can be updated so that subsequent primitives which lie behind the depth threshold are culled (i.e. not included in the display list for a tile). This helps to reduce the number of primitive IDs included in a display list for a tile which reduces the amount of memory used by the display list and reduces the number of primitives which a hidden surface removal (HSR) module needs to fetch to perform HSR on the tile. | 12-17-2015 |
20150363969 | Setting A Display List Pointer for Primitives in a Tile-Based Graphics Processing System - A tiling unit assigning primitives to tiles in a graphics processing system which has a rendering space subdivided into a plurality of tiles. A primitive is assigned to a tile by including a primitive ID of the primitive in a display list for the tile. If a primitive, or a mesh of primitives entirely covers a tile such that all of the previous primitives in the tile are obscured (i.e. hidden) then a start pointer of the display list can be moved to thereby skip the obscured primitives. In this way, a hidden surface removal (HSR) module will not fetch the primitives which would ultimately be hidden by the primitive or the mesh which entirely covers the region. This method therefore reduces the number of primitives which are fetched by the HSR module. | 12-17-2015 |

20150109288 | Random Accessible Lossless Parameter Data Compression for Tile Based 3D Computer Graphics Systems - A method and apparatus are provided for compressing vertex parameter data in a 3D computer graphic system, where the vertex parameter data is a data block relating to a plurality of vertices used for rendering an image. The data relating to each vertex includes multiple byte data relating to at least one parameter. The parameters include X, Y and Z coordinates and further coordinates for texturing and shading. The multiple byte data is divided into individual bytes and bytes with corresponding byte positions relating to each vertex are grouped together to form a plurality of byte blocks. | 04-23-2015 |

20110304608 | DISPLAY LIST CONTROL STREAM GROUPING IN TILE BASED 3D COMPUTER GRAPHICS SYSTEM - A method and apparatus are provided for rendering a 3 dimensional computer graphics image. The image is subdivided into a plurality of rectangular areas and primitives which may be visible in the image are assigned to respective ones of a plurality of primitive blocks. A determination is made as to which primitive blocks contain primitives which intersect each rectangular area. The rectangular areas are then grouped into a plurality of fixed size groups and control stream data for each of the fixed size groups is derived, this control stream data including data which determines which primitive blocks are required to render the rectangular areas in each respective first fixed size group. The control stream data is then used to render the image for display. | 12-15-2011 |
