WebFirst, facet model is used to present a complex surface. Then, a spring-mass model based on energy function is used to flatten the 3D mesh surfaces into 2D patterns. The surface elastic deformation energy distribution is depicted by a color graph, which determines a surface cutting line. WebThis study describes surface flattening based on minimum energy methods according to the property of different fabrics. Firstly, through the geometric feature of a 3D surface, the less transformed area can be flattened on a 2D platform by geodesic. ... S. S. F. Chen, andM. M.

WebApr 30, 2008 · This paper addresses the problem of fitting flattenable mesh surfaces in R 3 onto piecewise linear boundary curves, where a flattenable mesh surface inherits the isometric mapping to a planar region in R 2 . The developable surface in differential geometry shows the nice property. WebMay 27, 2014 · Purpose – The purpose of this paper is to find the pattern with minimal deformation energy while developing from 3D designed garments. Moreover, darts are generated to further reduce deformation energy. The aims of the energy‐based flattening method are to reduce the difference between 3D designed garments and 2D flattened … engineering dynamics limited ontario canada

WebUrban 3D surface reflectance is a critical parameter for the modeling of surface biophysical processes. It is of great significance to enhance the accuracy of reflectance in urban areas. Based on the urban solar radiative transfer (USRT) model, this study presents a methodology for estimating urban reflectance using the sky view factor (SVF) derived from airborne … WebJun 11, 2024 · This 3D garment can be modified in 3D model space by free-form deformation (FFD) tools [2] to obtain the new 3D garment. However, what fashion industries need is not 3D simulation but 2D patterns that can be used in the manufacturing processes. Thus, we need surface flattening technology to produce this model. WebOct 12, 2015 · Abstract A self-folding structure fabricated by additive manufacturing (AM) can be automatically folded into a demanding three-dimensional (3D) shape by actuation mechanisms such as heating. However, 3D surfaces can only be fabricated by self-folding structures when they are flattenable. Most generally, designed parts are not flattenable. dreamer occasion
