A Research On The Method Of Mannequin Modeling Based On Universal Software

This thesis mainly researches the method of mannequin modeling using the universal softwares. According to the differences of modeling methods and functions between soft wares, it reasonably arranges the application of every kind of software in the process of reconstructing the body surface. It considers the distribution of feature points from aspects of the geometric characteristics of human body, the relationship between the body and the clothing and modeling methods. According to the distribution of feature points, it divides the human body into regions and calculates the number of cross-sections within each region. It does curve fitting experiment using lines supported by each kind of software, and it selects the curves of relative good fitting position by the comparison of fitting error.It compares the difference between u loft and uv loft by experiment. It sets up different levels of cross sections and analyzes the quantity of surface fitting and the effects of different levels to the quantity of surface, according to the data of fitting error from rapidform xov and the visual effects .The results showed that:piont cure of 3ds Max is the best fitting condition when there are 60 pionts of uniform distribution on a cross section.Because the longitude section curves ask to build matchups with the points on the cross section curves, it uses u loft as the specific way of mannequin modeling. By analyzing the error of the surface fitting of piont curve, it finds out when there are 60 points and there are 60, 70 or 80 cross sections, the quantities of the curve fitting are all good, and it also accomplishes the goal of reducing the file size. Considering from the angle of simplifying the operation and reducing data, using 60 levels to reconstructing the body modeling is the optimized choice.
