Rendering optimization method and device

Abstract

The invention discloses a rendering optimization method and a device, wherein the display fluency of images is ensured and the frame-dropping phenomenon is avoided when the drawing and merging function is realized for a variety of types of mobile terminals. According to the method, the caching operation is conducted for a plurality of established rendering commands and vertex data associated with each rendering command. After that, the judgment and the analysis on the data volume of the vertex data, the GPU of a display card and a currently adopted operating system are conducted. If the data volume of the currently cached vertex data is smaller than or equal to a vertex data threshold, and / or the GPU belongs to a logic type set and the currently adopted operating system belongs to a system type set, at least two rendering commands among the plurality of rendering commands and having the same material identifier are merged. All merged rendering commands are then drawn. Finally, the vertex data associated with each rendering command are copied into a consecutive system memory and then are sent to a graphic rendering application program interface from the system memory.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a rendering optimization method and device. Background technique [0002] The Open Graphics Library (OpenGL) can be used for two-dimensional images or three-dimensional images, and is a powerful and convenient underlying graphics library. When using OpenGL to draw primitives, if the Vertex Buffer Object (VBO) is not used, the vertex data to be drawn is stored in the memory of the client in the form of a vertex array, and each time the drawing function is called (for example, : glDrawArrays or glDrawElements), when the Graphic Processing Unit (GPU) accesses the system memory to copy the vertex array, it needs to go through the graphics card bus to the motherboard bus and finally to the system memory. This access process is actually very inefficient. The role of VBO is to cache the vertex array that needs to be copied every time in the graphics card memory. Through VBO, ...

Problems solved by technology

[0005] In the prior art, for various types of mobile terminals, after turning on drawing and merging on a specific model, there will be problems of unsmooth picture display or frame drop, and the merging strategy is a unified strategy, and various applications can only be selected when they are released. Draw merge function or turn off draw merge function, this will lead to in order to avoid the problem of the machine not smooth or frame drop problem, and render merge optimization will be turned off on all types of mobile terminals, but turning off draw merge function will take up more CPU consumption, which is obviously not the optimal solution
