Much recent research has focused on obtaining rich interaction with 3D environments by means of advanced devices and 3D interaction metaphors. 3D widgets or manipulators, similar to our virtual tools, are presented in [13; 32]. These works focused on providing support for 3D widget construction, while we concentrate more on the integration of multiple tools in a single dynamic environment. We are not aware of any attempts to apply the results of 3D interaction
research to enhance animation capabilities.
