Abstract

The invention discloses a display refreshing method and system for 3D applications. The method comprises the following steps: displaying the last rendering result through storing a 3D application and generating a corresponding source texture according to the last rendering result; calculating a rectangular area of the screen change between the current screen display and the last screen display of the 3D application; setting the offset size of a view port according to the rectangular area, recalculating a projection matrix, drawing the rectangular area and generating a corresponding updating texture according to the drawing result; mixing the updating texture with the source texture, drawing to the view port, and updating and displaying the screen display so as to complete the display refreshing of the 3D application. According to the display refreshing method and system for 3D applications, only the area which is changed in allusion to a screen display interface is refreshed, so that the CPU occupancy rate is greatly reduced and the 3D scene rendering efficiency is remarkably improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a display refresh method and system for 3D applications. Background technique [0002] With the continuous development of mobile terminal technology, mobile terminals such as mobile phones have more and more functions. Existing smart phones are very rich in functions, and 3D-based visual experience effects are becoming more and more popular, and more and more 3D applications are running on embedded devices. Applications based on OpenGLES (OpenGL for Embedded Systems, a subset of OpenGL 3D graphics API, designed for embedded devices such as mobile phones, PDAs, and game consoles) generally refresh the entire screen, which will take up A large number of CPU and GPU resources lead to increased power consumption of embedded devices, reduced system performance, and directly affect the battery life of embedded devices. [0003] Therefore, the prior art still needs to...
