Method for rendering computer simulation scene

Abstract

The invention provides a method for rendering a computer simulation scene. The method comprises the steps that: a central processing unit (CPU) builds a particle initial data and informs a graphics processing unit (GPU) of the initial data when a particle system is initialized; in each rendering frame, the CPU informs the GPU of the time offset amount of the current frame relative to the initial data generated during the building, the GPU determines the particle attribute information of the current frame for scene rendering according to the time offset amount and the initial data, and displays the particles of the current frame on a screen of a scene observation device according to the particle attribute information currently confirmed. The rendering effect is improved after the method is adopted.

Description

technical field [0001] The invention relates to computer application technology, in particular to a computer simulation scene rendering method in computer graphics processing. Background technique [0002] At present, in order to enhance the reality of the scene and the degree of immersion to the user, the computer simulation system introduces particle systems into its rendering system to simulate various natural phenomena. Particle system is a technology in 3D computer graphics that simulates some scenes with blurred phenomena in reality. For these blurring phenomena, it is difficult to achieve realistic visual effects using other traditional rendering techniques. Phenomena that are often simulated using particle systems are fire, explosions, smoke, water flow, sparks, fallen leaves, clouds, fog, snow, dust, meteor trails, or abstract visual effects such as glowing trails. The emergence of particle system technology has also brought a qualitative leap in the improvement o...

AI Technical Summary

Problems solved by technology

[0012] In the case of a small number of particles, the above-mentioned traditional particle system implementation scheme can well simulate the rendering of the scene, but if there are large-scale particle rendering needs, such as rain, snow, etc., this method will affect the overall performance. will be bigger

[0013] It can be seen that using the traditional particle system to realize the rendering of the computer simulation scene has the problem of low rendering efficiency
