The embodiment of the invention discloses a special effect video generation method and device, equipment and a storage medium. Determining the motion information of the virtual fluid in the current frame and the first state information of the virtual fluid surface in the previous frame; wherein the virtual fluid is placed in a virtual container; determining second state information of the virtual fluid surface in the current frame based on the motion information and the first state information; wherein the second state information comprises second fluid surface orientation information and second disturbance information; and rendering the fluid surface state of the current frame according to the second fluid surface orientation information and the second disturbance information to obtain a fluid motion special effect graph corresponding to the current frame. According to the embodiment of the invention, the fluid surface state is rendered through the second fluid surface orientation information and the second disturbance information of the current frame, and the fluid motion special effect graph corresponding to the current frame is obtained, so that the calculation amount of simulating fluid motion can be reduced, and the efficiency of generating the fluid motion special effect video is improved.
Description
technical field [0001] The embodiments of the present disclosure relate to the technical field of image special effects processing, and in particular, to a method, apparatus, device, and storage medium for generating special effects video. Background technique [0002] Most of the existing flow object (fluid for short) simulation algorithms are based on the particle dynamics (Position BaseDynamic, PBD) algorithm. The principle is to abstract the fluid into multiple particles and calculate the motion state of the particles in each frame to generate fluid motion. special effects video. However, this algorithm has a large budget and cannot generate fluid motion special effects videos in real time. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a method, apparatus, device, and storage medium for generating a special effect video, which can reduce the amount of calculation for simulating fluid motion, thereby improving the efficiency of generat...
