Problems solved by technology

And the worse situation is that the camera is located in this effect, causing the effect to almost fill the screen, and at the same time it has a very high redraw rate, resulting in a drop in the number of frames drawn
[0005] Then, special effects in general scenes do not require very high details

Embodiment Construction

[0018] An optimization method for particle rendering, the main steps of which are as follows:

[0019] 1) According to the zoom factor, in order to draw off-screen particles, create a new rendering target;

[0020] 2) Draw the particles into the newly created render target;

[0021] 3) Soften the edges of the particles;

[0022] 4) Create a new screen effect, use off-screen particles as textures, and draw them on the main frame buffer;

[0023] The particle optimization method is suitable for soft and fuzzy particles, and the particles with low resolution are used to replace high-resolution particles so that there will be no obvious distortion;

[0024] The application environment of the particle optimization method is that the particles themselves and the pixels of the scene are superimposed;

[0025] The particle optimization method uses overlay pixels to blur the edges of pixels.

Abstract

The invention relates to a particle rendering optimization method, in particular to a rendering optimization method of particles with a high fill rate, which belongs to the technical field of computer graphics. By using off-screen rendering with low resolution, the performance can be greatly improved, and the consumption of a particle system can be more controllable. Although distortion cannot be completely eliminated, an acceptable rendering effect can be achieved by improvement with a fuzzy method, a stencil buffer method and the like.

Description

[0001] technical field [0002] The invention relates to a rendering optimization method, in particular to a rendering optimization method for particles with a high filling rate, which belongs to the technical field of computer graphics. Background technique [0003] With the development of rendering technology, there are higher requirements for scene rendering in the production of various large-scale 3D online games. In order to meet the higher requirements of players, a large number of particle systems are commonly used to model various scene effects, such as fireworks, explosions, various weather effects, etc. [0004] Particle systems need to simulate complex motion systems, such as a snowstorm or an explosion, which require a large number of triangles to be drawn. And what's worse is that the camera is in this effect, causing the effect to almost fill the screen, and it has a very high redraw rate, resulting in a drop in the number of frames drawn. [0005] Then, ...
