#### Abstract

Curve and physically based surface modelling techniques are becoming more and more active in geometric modelling of three-dimension (3D) objects since the former can create 3D models easily and quickly and the latter can produce more realistic appearances. In this paper, we present a curve and physically based surface modelling technique to create 3D models of virtual characters. This technique is based on physically based curve deformation. With such a technique, a character model is created from a number of surface patches. Each surface patch is obtained from physically based deformable curves. We introduce sculpting forces into a vector-valued ordinary differential equation to control the physically based deformations of curves. By describing concentrated sculpting forces with a sine series, we present an efficient analytical solution of the ordinary differential equation which can determine physically based curve deformations quickly. An example of character modelling is presented to demonstrate the application of our proposed technique.
