Method for synthesizing three-dimensional fluid scenes with sense of reality and space-time continuity

Abstract

The invention discloses a method for synthesizing three-dimensional fluid scenes with the sense of reality and space-time continuity. The method includes the steps that firstly, height values of fluid particles are calculated according to a fluid reestablishment method based on SFS, and then hierarchical division is conducted on the three-dimensional scenes according to height gradients; fluid wave components are extracted from different layers respectively and clustered, so that space continuity is guaranteed; class components acquired from the corresponding layers are rearranged and repositioned, and the three-dimensional fluid scenes with the sense of reality are synthesized; smoothing for height information is adopted in a transition region of the synthesized scenes; Hash mapping tables of height and color are established, and color remapping is conducted on the appearance of the particles in the transition region; height information, color information and texture coordinate information of the particles are transmitted, and then a synthesis result with space-time continuity is acquired. When the method is used for synthesizing multiple fluid scenes with challenges and fluid scenes with different scales, the satisfying synthesis result can be acquired.

Description

technical field [0001] The invention relates to a method for synthesizing a large realistic fluid scene in a three-dimensional space. A large-scale three-dimensional virtual fluid scene is synthesized according to a certain frame height information of a fluid video. The fluid scene synthesized in real time has temporal and spatial continuity and realism, and can maintain Global properties of the original video. Background technique [0002] Fluid natural landscapes can be seen everywhere in the objective world, and fluid scene synthesis is widely used in computer animation, computer games, film and television special effects, military management and other fields. At present, there are mainly two types of methods for generating fluid natural landscapes: the simulation drawing method based on the laws of fluid physical motion in graphics and the construction of fluid scenes based on video images. Physically-based research methods have been an active research topic in the fiel...
