Abstract
A software designated as 3DASBS has been used for the analysis of the silkworm spinning behaviour. However, its use has been limited to the expensive workstations that can run specialized 3D graphics libraries. In this paper, we report on the development of a new visualization system of the silkworm spinning behaviour based on 3DASBS that can be run on the widely used Windows 98/NT platform. It can display a silkworm body more realistically by overlapping spheres. Since all the procedures are written as object classes using an object-oriented programming language, the system can easily be extended by inheritance of the classes.
