Data-driven smoke animation synthesis method and data-driven smoke animation synthesis system

Abstract

The invention relates to a data-driven smoke animation synthesis method, which comprises the following steps of: generating two-dimensional smoke contour data according to a smoke data set; obtaininga smoke generation model through a training generation network of the two-dimensional smoke contour data; generating the two-dimensional smoke contour data into a three-dimensional smoke sequence through the smoke generation model; and rendering the three-dimensional smoke sequence to generate a smoke animation. According to the smoke animation synthesis method provided by the invention, the smokeinformation and the control mode are simpler and more visual, the authenticity of the smoke animation under simple input is kept, and the smoke animation with controllable shape and sense of realityof a user can be generated in real time.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method and system for controllable synthesis of fluid animation. Background technique [0002] The simulation of natural phenomena has always been one of the hot issues in computer graphics research. Among them, fluid simulation, especially the real-time modeling and controllable animation technology of smoke animation, has more and more extensive application requirements and values ​​in various fields such as film and television special effects, advertising, 3D game development, and virtual reality. However, natural smog is a complex physical phenomenon. Due to the influence of various factors such as buoyancy, obstacles, wind energy input and internal eddy, the internal concentration distribution of smog is irregular, and the shape is also various, which can be uniform. It can also have violent eddy current changes, its geometric shape is extremely irregular, and the boundar...
