Embodiment Construction

[0065] The present invention will be further described below in conjunction with accompanying drawing:

[0066] The system of the present invention includes a cloth modeling unit, an information collection unit, an optimized cloth model unit, a collision detection unit, and a cloth tearing unit; the back end of the system of the present invention includes a cloth texture database, a rigid body model library, and various material cloth model libraries.

[0067] The cloth modeling unit is used to build the cloth model including the triangular mesh of the mass spring model.

[0068] The information collection unit is to collect and store the positions of the vertices of the cloth model, the relationship between edges and vertices, the length of edges, the relationship between surfaces and vertices, and the adjacency of surfaces, and use these information to establish Half-edge data structures.

[0069] The optimized cloth model unit is used to add texture maps to the original clo...

Abstract

The invention relates to a system for dynamically simulating cloth tearing. The system establishes a cloth model by utilizing a mass spring model, so that cloth is decomposed into multiple triangular patches; then, cloth tearing is completed; a Half-edge data structure is added while modelling is carried out; related information of the position of a cloth vertex, the relationship between an edge and a vertex, the relationship among the length of the edge, a surface and the vertex and the adjacency relationship of the surfaces is stored; a bounding box distance field based on the Euclidean distance is created, and used for completing collision detection; the cloth tearing simulation efficiency is increased; a steel body model is created; the gravitational acceleration is added to a rigid body or the cloth, so that the rigid body and the clock are collided; and then, tearing is generated. The system disclosed by the invention can be widely applicable to dynamic analogue simulation of the cloth in design and manufacture and film and television entertainment.

Description

technical field [0001] The invention relates to the field of computer cloth simulation, in particular to a system for simulating the collision between cloth of different materials and a rigid body. Background technique [0002] The real and fast cloth simulation animation technology is a hot spot in the field of computer graphics in recent years. Cloth animation simulation is an important part of computer animation, and the animation generated by simulating cloth has great application value in design, manufacturing, film and television entertainment, etc. [0003] In real life, cloth is often subjected to forces in various directions, resulting in deformations in different states. At the same time, collisions with rigid bodies are inevitable. Cloth is a flexible object that is easy to tear, but due to the extremely The characteristic of linear change makes the simulation of cloth become a major research hotspot and difficulty in computer graphics. [0004] Times are advanc...
