Human body and clothing model collision detection and processing method based on HRBFs

Abstract

The invention provides a human body and clothing model collision detection and processing method based on HRBFs, and the method takes three-dimensional clothing and a human body model as objects, carries out the collision detection of a plurality of three-dimensional models through employing a hermit radial basis function, carries out the collision processing through combining with a grid deformation algorithm, and finally achieves the three-dimensional human body fitting effect in a computer through cloth simulation. The method mainly comprises the following steps: generating a three-dimensional human body model by utilizing human body feature sizes and joint point information; performing collision detection and processing on all the selected clothing models and human body models; and performing cloth simulation on the garment model, and displaying the fitting effect of the human body. According to the method, the collision-free effect of the human body model and the garment model which penetrate through each other can be achieved, manual adjustment is not needed, and the method has certain universality and practicability.

Description

technical field [0001] The invention relates to a human body and clothing model collision detection and processing method based on HRBFs. Background technique [0002] In the virtual fitting system, the clothing model has rich fold details and is easily deformed. It will inevitably collide with the human body model and penetrate each other. Therefore, collision detection and processing are the key factors that determine the fitting effect. How to quickly detect the collision between the clothing and the human body model and make a response that conforms to the laws of physics is a key issue that affects the fitting experience. [0003] The essence of collision detection is to judge whether the basic elements of the clothing model and the human body model intersect in three-dimensional space. It is generally divided into continuous collision detection and discrete collision detection. [0004] 1. Discrete collision detection method: It mainly detects whether two static model...

Problems solved by technology

Because only the collision point is processed without considering the global situation, this method is not robust, but it is worth referring to for improvement
