Abstract

The invention relates to a video generation method and device and a storage medium. The method comprises the following steps: determining an initial speed and an initial position of a fluid in a weightless state; when an external force is applied to the fluid, determining the external force applied to each particle in the fluid; then determining a predicted position of each particle in each frame in a preset time period; constructing a density constraint equation of each frame of each particle based on the predicted position of each frame of each particle; obtaining a plurality of video frames of the fluid based on the density constraint equation of each particle and each frame; and obtaining the video in the preset time period. The authenticity of fluid vibration, merging and splitting states under the simulated weightlessness condition is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a video generation method, device and storage medium. Background technique [0002] In related technologies, a series of progress has been made in real-time animation simulation algorithms and technologies with high realism for various substances, but they are mainly concentrated on PC and server platforms, such as using smooth particle hydrodynamics (SPH) and material point method Classical algorithms such as (MPM) perform off-line simulation and simulation of a large number of particles. It is still a challenge to perform real-time physical animation simulation calculations with a high degree of realism on mobile devices or edge computing nodes with few computing power resources. [0003] Therefore, the present disclosure provides a video generation method, device and storage medium, which simulates the running state of the fluid under stress under the condition...
