Optimization of Fabric Deformation Based on Wind Field Simulation Based by Bernoulli Equation

Cloth simulation usually refers to using computer programs to simulate the true representation of flexible tensile materials in nature. This article is based on the traditional Mass-Spring model. The main improvement method is: giving a reasonable range of Hook variable to the original model, constraining the abnormal deformation of the spring under the action of powerful external force, which is called "Hyperelastic phenomenon"; In the case of the same types of traditional force, imitating the natural performance of the wind field to cloth, increase the pressure difference caused by the Bernoulli effect, resulting in a more realistic cloth simulation in wind field; Using the Symplectic Euler method to solve the differential equation of particle motion, since this method belongs to the implicit Euler method, it has a more stable performance than the explicit Euler method; Using mature geometric calculation formulas, collision detection is realized with less space and time complexity. Through this experiment, it is verified that the cloth simulation optimization based on this method has a better real-time and On-site reduction effect.
