Method and device for superposition of particle file and video

Abstract

The invention provides a method and device for superposition of a particle file and video. The method includes the steps of receiving a background check request upon the current particle file and searching the background of the particle file, establishing a two-dimensional panel and panel texture of the two-dimensional panel when the background of the current particle file is not searched, extracting a preset video file and adding the preset video file into a cache of the panel texture, and updating the background of the current particle file according to the cache of the panel texture and the two-dimensional panel. The method and device for the superposition of the particle file and the video can avoid that due to the fact that a video file is so big in size, a superposition result of the particle file and the video is discontinuous.

Description

technical field [0001] The present application relates to the field of computer graphics, in particular to a method for superimposing particle files and videos, and a device for superimposing particle files and videos. Background technique [0002] In 1983, Reeves proposed the method of modeling fuzzy objects by particle system. The basic idea is to regard fuzzy objects as particle clusters composed of many particles, and particles can be regarded as simple points. Each particle has its own attributes, such as color, shape, size, life cycle and speed, etc. The dynamic properties of the particle determine its state at different moments, and the particle changes continuously over time. [0003] Particles are emitted by a particle system, and a particle system is composed of a particle emitter and multiple particle influencers, that is, a particle system produces particle effects. [0004] Usually, the rendering of particles is done by the graphics processor GPU. When composit...

Problems solved by technology

[0005] The problem in the above background technology is that the size of 1920*1080 is generally used in program production. The larger the size, the longer the copying time. The video playback is 25 frames per second. Due to the speed of copying the buffer from the GPU to the memory Relatively slow, poor real-time performance, using this method, only a dozen frames can be played in 1 second, and the effect seems to be flickering, discontinuous

It has a great impact on the user's vision. At the same time, after the effect of particle creation is output, the file is played at 25 frames per second, which causes the phenomenon of inconsistency between the creation and the actual use effect.
