Abstract
3D graphics applications require managing and displaying objcts as well as handling events. These tasks are quite complex for applications to worry about and are comon to many applications. Therefore, many attempts have ben made to provide toolkits with these capabilities for those applications. This paper presents a toolklt that is easy to use and well suited for the modeling and rendering tasks. The object-oriented programming techniques used in designing the toolkit make it flexible and easily extensible.
