Real-time interactive fluid simulation method based on Dynamic SDF collision

The invention discloses a real-time interactive fluid simulation method based on Dynamic SDF collision, and relates to the technical field of computer graphics and computational fluid mechanics. Sorting the fluid particles in the video memory based on a computational shader; converting dynamic grid information in the scene into a dynamic symbol distance field in real time based on a calculation shader and taking the dynamic symbol distance field as boundary information; updating the positions of the fluid particles according to the boundary information by using a position-based fluid particle simulation method; and drawing a small ball in a screen based on the updated position of the fluid particle, and outputting a depth map and a thickness map for fluid coloring rendering to obtain a final color. According to the method, the running speed requirement under real-time application environments such as games and the like is basically met, a Dynamic SDF is introduced to efficiently process collision between flui
