Three-dimensional graph processing system of mobile visual media

Abstract

The invention discloses a three-dimensional graph processing system of a mobile visual media. The three-dimensional graph processing system comprises a three-dimensional graph display module, a novel raster architecture module, an image reverse subdividing module and a graph transmission module, wherein the three-dimensional graph display module acquires and calculates the geometric position and colour information of an object in a three-dimensional coordinate system, interpolating the calculated information, mapping a texture image onto a model, and outputting an image; the novel raster architecture module adopts a novel multisampling method and a high-speed texture caching method to carry out block colouring, texture filtering and intercepting on a mobile image, thus the access frequency to an external memorizer is reduced; the image subdividing module adopts a subdividing wavelet transform technology, maintains rules and properties of a subdivision surface based on a Lifting technology structure and carries out surface modelling subdivision on a three-dimensional image; and the graph transmission module optimizes and supports multiple standard communication protocols by building a communication protocol stack. The three-dimensional graph processing system disclosed by the invention can simplify and rapidly display a geometric graph on the mobile visual media, and is low in power consumption and stable in transmission.

Description

technical field [0001] The invention relates to the field of mobile visual media, in particular to a three-dimensional graphics processing system for mobile visual media. Background technique [0002] The living environment of modern human beings is so complicated, in which there are various and massive visual media, and different visual media carry different visual information. The mobile visual media mainly refers to the new media that utilizes digital radio and television terrestrial transmission technology to meet the audio-visual needs of mobile people. Due to the uniqueness of mobile visual media, there are great requirements for fast image display and data transmission. Three-dimensional graphics will greatly enhance the realism of digital images. Compared with two-dimensional graphics, three-dimensional graphics have richer information about the three-dimensional world. The existing mobile visual media lacks content, poor display effect, unstable display signal, and...
