This paper presents a model for simulating flexible surfaces of cloth
objects. The model is to simulate cloth deformations in three-dimensio
nal (3D) space from two-dimensional (2D) patterns by using the finite
element method (FEM) with geometric constraints. A 3D form is obtained
from a 2D pattern based on the geometric constraints and material pro
perties of cloth objects. The geometric constraint of cloth objects wh
ich differs from that of other materials is presented as an important
factor in the simulating procedure. Various approaches and difficultie
s involved in simulating flexible surfaces are also briefly discussed.
Finally, an example is given to describe the model. (C) 1997 Elsevier
