Several 3-D user interaction techniques that employ multiple viewports have been previously proposed to provide a secondary view rendered from another viewpoint for efficient operations and seamless interaction between multiple virtual scenes. However, projection methods and transformation hierarchies are used in different and limited ways in existing techniques. In this paper, proposed is a general framework for multi-viewport interfaces to support arbitrary types of transformation hierarchies, including previous techniques. We focus on coordinate systems of the scenes, the user and the window frames, and thoroughly examine characteristics and the usability of the pairwise relationship among them. As a result, we found 10 useful patterns of pairwise relationships, and 38 transformation hierarchy patterns. Our framework not only supports typical previous techniques, but also enables a comparison of related systems and suggests new 3-D user interfaces.
