Abstract:

Aiming at the problems of serious distortion in the body deformation of 3-D garment simulation, an algorithm of left-right section structure of human body was provided. The body wasdivided into front and rear parts and deformed, respectively. First of all, the processed point cloud body was used to identify the feature of the body, and the points on the shoulder line and side seam were selected and designated as the feature points. The 3-D coordinates of these points were marked and obtained. Secondly, the space quadric equation was introduced and constructed as left-right section model by analysing coordinate data from these feature points. Thirdly, based on the surface reconstruction of reverse engineering, the 3-D coordinates of specified feature points were substituted into the quadric equation, the system of non-homogeneous linear equations was constituted, and the parameters of the system were solved and the quadric equation coefficients were obtained. In the end, the quadric surface equation constituted the left-right section was applied to the simulation of human body, and a left-right section containing the feature points was built. The algorithm accurately constructs the left and right section of the body which divides the body into two parts. The section a good effect when the section is applied to the body deformation of the garment simulation.

Key words: body deformation, 3-D garment simulation, left-right section, surface reconstruction
