Embodiment Construction

[0059] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0060] Most of the current research still focuses on improving the efficiency of the algorithm, and it is not necessary to consider the scope of application of the algorithm from the perspective of versatility. In reality, a large number of 3D clothing model files are built using general modeling software (such as Maya, 3DSMax, etc.), and the main feature of the model is that the surface is composed of a large number of irregular triangular faces. The simulation method for calculating regular grid particles is not practica...

Abstract

The invention discloses a particle spring structure based universal garment three-dimensional model simulation method. The method comprises: obtaining information of a top point and a triangular surface of a garment model, constructing an adjacency relation, and establishing a particle spring structure model of a garment; and based on a numerical solving algorithm, obtaining a motion track of a mass point at t moment by iterative operation. The invention furthermore discloses a particle spring structure based universal garment three-dimensional model simulation system. According to the simulation method and system, a spring model is simplified into a structure spring and a bending spring, so that while a simulation result is not influenced, the calculation amount is reduced and the simulation efficiency is improved; a particle motion prediction mechanism is introduced, so that the reliability and error correction capability of simulation are improved, and the simulation result better conforms to physical properties of garment cloth; and particle velocity data do not need to be calculated and only the position of the top point on the triangular surface needs to be calculated, so that the simulation speed is increased.

Description

technical field [0001] The invention relates to simulation analysis, in particular to a clothing three-dimensional model simulation method and system based on particle spring structure analysis. Background technique [0002] Computer simulation of cloth and clothing has always been a hot and difficult research topic at home and abroad. In virtual reality technology, cloth is a flexible object. Unlike the 3D simulation of ordinary rigid bodies, the surface shape of cloth is deformed at any time. Furthermore, there will be more problems to be solved in the simulation of 3D garments composed of cloth and garment parts. In addition to authenticity, real-time performance and interactivity should also be emphasized, and complex collision detection with the human body will eventually be required. The research on modeling and simulation of flexible fabrics and 3D clothing has attracted much attention, both internationally and domestically. In addition to the above theoretical and t...
