Abstract

The invention discloses a cloth simulation method, system, electronic equipment and storage medium of an anisotropic material based on a spring mass point model, and belongs to the field of simulation technology, including discretizing the cloth by triangular mesh division, and obtaining each material on the cloth. Triangle vertex coordinates; spread the cloth in the two-dimensional texture coordinate system to obtain the two-dimensional texture coordinates of the triangle vertices; perform spring particle deformation calculations on each triangle vertex to obtain new coordinates at each time node; calculate the surface The normal vector of the triangle is rendered, and the effect of dynamic deformation visualization is drawn in real-time simulation; the iterative deformation calculation of the particle spring for the triangle vertices includes the elastic force between any two vertices in the triangle vertices, and the strength coefficient of the elastic force includes the two-dimensional texture coordinate system X-axis and Y-axis directions. The invention introduces an anisotropic bending method, so that the cloth simulation can control the anisotropic behavior of the cloth by adjusting the two-dimensional parameters of the local material direction.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a cloth simulation method, system, electronic equipment and storage medium of an anisotropic material based on a spring particle model. Background technique [0002] In the real world, the material properties of cloth are often anisotropic, and the stretching and bending properties of cloth are inconsistent in different directions, which enhances the diversity of details such as wrinkles on the cloth surface. [0003] In order to consider anisotropy, cloth simulation often uses finite element techniques for complex modeling and calculations, such as Data-Driven Elastic Models for Cloth: Modeling and Measurement; these methods can accurately model local anisotropic stretching and anisotropy of cloth. Itemically curved, but tends to be computationally expensive and requires a very good triangular mesh representation of the cloth. [0004] In actual engineering, considering fac...
