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 presente
d to demonstrate the application of our proposed technique.
