Efficient pre-computing of simplified vector data for rendering at multiple zoom levels

Номер: US20120206469A1

Автор: David Eustis, Tudor Hulubei

Принадлежит: Google LLC

Aspects of the invention relate generally to accessing, storing, and processing vector data to represent various geographical features such as roads, rivers, lakes, countries, continents, and oceans on one or more maps. More specifically, the vector data may be pre-simplified for rendering at different zoom levels. The simplification process is based on removing vertices from vector data in order to reduce the number of points in a given polygon or line. As this process is very expensive in terms of time and processing power, the system and method allow for estimation of the proportion of vertices which that would be removed from the original geometry. Based on this estimation, one may decide whether or not the simplification is worth the effort to compute and store the simplified data.

Принадлежит: ARM LTD

In a tile-based graphics processing system, when an overlay image is to be rendered onto an existing image, the existing tile data for the existing image from the frame buffer in the main memory is pre-loaded into the local colour buffer of the graphics processor (step 41 ). The overlay content is then rendered and used to modify the tile data stored in the colour buffer (step 44 ). When the data for a given sampling position stored in the tile buffer is modified as a result of the overlay image, a corresponding dirty bit for the tile region that the sampling position falls within is set (step 45 ). Then, when all the rendering for the tile has been completed, the dirty bits are examined to determine which regions of the tile have been modified (step 46 ). The modified tile regions are written back to the output image in the frame buffer in the main memory (step 47 ), but any regions whose dirty bits have not been set are not written back to the frame buffer in the main memory.

Embodiments of the invention set forth a technique for animating objects placed across a surface of a graphics object. A CAD application receives a set of motions and initially applies a different motion in the set of motions to each object placed across the surface of the graphics object. The CAD application calculates bounding areas of each object according to the current motion applied thereto, which are subsequently used by the CAD application to identify collisions that are occurring or will occur between the objects. Identified collisions are cured by identifying valid motions in the set of motions that can be applied to a colliding object and then calculating bounding areas for the valid motions to select a valid motion that, when applied to the object, does not cause the object to collide with any other objects.

Method and Apparatus for Converting Spherical Harmonics Representations of Functions into Multi-Resolution Representations

Номер: US20130120384A1

Автор: Nathan A. Carr, Wojciech Jarosz

Принадлежит: Adobe Systems Inc

An analytical method to efficiently convert a function that is stored in spherical harmonics into a function that is stored in a wavelet or mip map representation enables a variety of computer graphics functions to be efficiently performed. A function may be stored as a spherical harmonic representation and rotated in the spherical harmonic domain; the function can then be converted to a wavelet representation. The conversion method may be used to convert a spherical harmonic function to wavelets, and then an importance sampling technique may be applied to the wavelet representation to generate a set of importance samples for the function. The conversion method may be applied to convert a spherical harmonic representation into the wavelet domain, and an importance sampling technique may then be applied which samples the product of the function and another function in the wavelet domain.
