The combination of these elements is guided by intuitive user interactions using multiple modalities simultaneously, such that the map information is filtered to best respond to the user's request, and presented in a way that presents both the focus and the context in a map in an aesthetic manner. The system facilitates several use cases that are common to the users, including destination preview, destination search, and virtual map exploration. 1. A method for generating map graphics including two-dimensional and three-dimensional elements comprising:generating with a processor a graphical display of a two-dimensional base map with a display device;receiving with a multi-modal input device a user selection of a region of interest in the two-dimensional base map, the region of interest corresponding to only a portion of the two-dimensional base map;identifying with the processor a first footprint region in the two-dimensional base map, the first footprint region including the region of interest and a first portion of the two-dimensional base map outside of the region of interest;generating a three-dimensional graphical display of at least one building, terrain feature, or landmark located within the region of interest with the graphical display device; andgenerating a first two-dimensional graphical display in the first footprint region including at least one graphical element not present in the two-dimensional base map with the graphical display device.2. ...

Producing rendering outputs from a 3-d scene using volume element light transport data

Номер: US20200005519A1
Автор: Cuneyt Ozdas, Luke Tilman Peterson
Принадлежит: Imagination Technologies Ltd

Rendering system combines point sampling and volume sampling operations to produce rendering outputs. For example, to determine color information for a surface location in a 3-D scene, one or more point sampling operations are conducted in a volume around the surface location, and one or more sampling operations of volumetric light transport data are performed farther from the surface location. A transition zone between point sampling and volume sampling can be provided, in which both point and volume sampling operations are conducted. Data obtained from point and volume sampling operations can be blended in determining color information for the surface location. For example, point samples are obtained by tracing a ray for each point sample, to identify an intersection between another surface and the ray, to be shaded, and volume samples are obtained from a nested 3-D grids of volume elements expressing light transport data at different levels of granularity.

ALLOCATION OF PRIMITIVES TO PRIMITIVE BLOCKS

Номер: US20210027519A1
Автор: Howson John W., Redshaw Jonathan, Yang Xile
Принадлежит:

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. 1. A method of processing primitives in a computer graphics processing system in which primitives are allocated to primitive blocks at a primitive block allocation module of a computer graphics processing system , which includes a data store for storing a set of primitive blocks to which primitives can be allocated , wherein a primitive block is configured to store primitive data , the method comprising: (i) comparing an indication of a spatial position of the received primitive with at least one indication of a spatial position of at least one primitive block that is stored in the data store, and', '(ii) allocating the received primitive to a primitive block based on a result of the comparison, such that the received primitive is allocated to a primitive block in accordance with its spatial position; and, 'for each of a plurality of received primitivesprocessing primitive blocks including allocated primitives in the computer graphics processing system.2.
