Abstract
A generation method for generating a firework visual effect, a video generation method, an electronic device, and a non-transient computer readable storage medium are provided. The generation method includes: generating a center particle set and a spark particle set, the center particle set being used for forming a center part of the firework visual effect, and the spark particle set being used for forming a spark part moving along a path away from the center part in the firework visual effect; rendering particles in the center particle set to obtain a center particle primitive model set; rendering particles in the spark particle set to obtain a spark particle primitive model set; and superimposing the center particle primitive model set and the spark particle primitive model set to generate the firework visual effect.
