The Design of a Visual Tool for the Quick Customization of Virtual Characters in OSSL

This paper implements a visual tool for the quick customization of virtual characters in 3D virtual worlds with a three-layer structure based on the Open Sim and Second Life platforms and "Knowledge" theory. "Knowledge" refers to specific controlling conditions and the corresponding behaviors of virtual characters. The three-layer structure is divided into the data layer, entity layer, and implementation layer. The data layer is used to store the data needed by the virtual characters´ login and the behavioral control, the entity layer enables the exchange of data with the data layer and passes parameters to the implementation layer, and the implementation layer allows for realizing the knowledge of virtual characters with the support of the API in the Open Metaverse open source framework. Moreover, visualization of the tool is implemented through the interfaces provided by the entity layer. With this tool, users can generate a group of virtual characters quickly and conveniently at any place in a certain virtual world and select a variety of knowledge for diverse virtual characters.
