The invention provides a method and system for drawing and rendering layered graphs in real time. The method comprises the following steps of: S101, extracting adjacent application frames in a time horizon in the past, calculating a scene change rate, and verifying whether the scene change rate exceeds a preset change rate threshold value or not; S102, if the change rate does not exceed the threshold value, setting all the graph elements as a same layer, and if the change rate exceeds the threshold value, entering step 103; S103, re-obtaining a plurality of application frames between the adjacent application frames; S104, dividing all the re-obtained application frames into N areas in an equal-area manner, and obtaining a scene change rate between every two adjacent application frame in each area; and S105, calculating an average scene change rate in each area, and carrying out layering according to the sizes of the average scene change rates, and respectively drawing and rendering different layers. According to the method and system, layered graph management is carried out, so that the waste of calculation resources is avoided, and the graph drawing and rendering process can be efficiently completed.
Description
technical field [0001] The invention relates to the field of graphics rendering and rendering, in particular to a method and system for layered graphics real-time rendering and rendering. Background technique [0002] In today's real-time graphics rendering field, the speed of real-time graphics rendering and rendering is high, and the overall graphics must be fully presented, but graphics deformation, graphics rendering refresh rate is slow, and the hardware configuration of terminal equipment is getting higher and higher. The application of graphics not only gives users an intuitive experience, but also brings great challenges to the field of real-time graphics rendering. Whether it is a hardware product or a software product, graphics rendering is directly related to the quality of this product. In recent years, the methods of real-time graphics rendering have been published one after another. For different applications, the technologies used are different. Today's main r...
