Garment deformation method based on input human body posture real-time generation

Abstract

The invention discloses a garment deformation method based on input human body posture real-time generation. The scheme relates to main algorithms including a skeleton driven sensitivity analysis algorithm, a hybrid garment algorithm based on sensitivity and a random optimization scheme based on a greedy algorithm so as to construct a garment instance database. The algorithm flow is listed as follows: after one input posture is given, skin calculation and processing are performed on a skeleton according to the skeleton driven analysis method so that a human body skin model is obtained and subdivided into multiple single areas; garment samples similar to the posture of each area of the skin model are inquired in the constructed garment database; deformation processing is performed on each garment sample; then fitting is performed on the garment sample by using the hybrid garment algorithm so that an initialized garment deformation effect is obtained; and the penetration and friction effect processing is performed on the initialized garment deformation sample so that the final garment deformation effect is obtained. With application of the method, the garment deformation simulation process can be optimized and the lifelike garment deformation effect can be obtained.

Description

technical field [0001] The invention belongs to the fields of visual and digital clothing design and computer graphics, and in particular relates to a clothing deformation method generated in real time based on input human body gestures. Background technique [0002] In the past 20 years, physics-based clothing simulation has become a hot research field in the field of computer graphics. Its main job is to build different models for different shapes of clothing deformation behavior. These measures include the buckling effect model, the nonlinear tensile stiffness model and the contact self-collision model. In addition to the thin shell model, Kaldor et al. proposed a cloth simulation method based on yarn and knitting. Because the high-resolution cloth mesh simulation will bring a huge amount of calculation, in order to make the simulation more effective, researchers introduce adaptive mesh for clothing simulation. The current clothing simulation begins with simulating co...
