Abstract

The invention provides a method and a device for emitting particles. The method comprises the following steps of: receiving a selected particle system and an emitting attribute set up for the particle system, wherein the emitting attribute comprises the particle quantity N and particle emitting parameters and N is a positive integer; establishing N particle systems and configuring same particle emitting attribute to each particle system; and emitting the particles one by one at a preset interval by the N particle systems, and while emitting the particles, setting a coordinate value of the presently emitted particle along an emitting direction as zero and reducing or adding a coordinate location of the emitted particle along the emitting direction by a preset value. According to the method provided by the invention, the problem that a regular particle effect picture cannot be generated can be solved.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method for emitting particles and a device for emitting particles. 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] Particles are emitted in space. The coordinates of the three dimensions in space are X, Y and Z. The observer watches the particle effect fro...
