Abstract

The invention relates to a method and device for constructing a three-dimensional scene animation based on a particle system in a GIS system. The method comprises the steps that an operation instruction is received to design an animation effect; converting the reference design animation into a track taking mathematics as logic; optimizing and controlling each attribute, and expanding the attributeof the animation special effect of the three-dimensional scene; abstraction and reuse are carried out through multi-particle system animation, three-dimensional scene animation is extracted and optimized, and construction of the three-dimensional scene animation is completed. The three-dimensional animation effect with high efficiency and vivid effect is realized at the WebGis front end, and themethod is low in cost, high in efficiency and high in universality.

Description

technical field [0001] This application relates to the technical field of GIS systems, in particular to a method and device for constructing 3D scene animation based on particle systems in GIS systems, computer equipment, and readable storage media. Background technique [0002] WebGis 3D animation special effects belong to a kind of real-time rendering technology, including animation control and animation algorithm, and need to be used in combination with the WebGis field. Currently, computing acceleration and rendering cannot be performed through a powerful server. In today's increasingly fierce competition in the field of WebGis, if some scenes can be presented in an efficient 3D animation, it will greatly increase the performance and simulation of the WebGis system and enhance the sense of presence. [0003] Particle system is a set of technology formed by 3D graphics in practice, which uses a large number of particles to move and aggregate according to mathematical law...
