AbstractThe paper describes taxonomy for interactive manipulation of 3D objects using a 2D input device such as a mouse. The usual set of visualization parameters, eye position, reference point, and view up-vector, is adopted. The proposed classification divides the control models in three groups: Screen-based, Walk-through, and Object-based models. For each one of these models, translation and rotation geometric transformations may be performed. Independently, one may control other viewing parameters such clipping plane positions with respect to the eye point, and distance from eye to reference point. Existing manipulation schemes are analyzed according to the proposed classification. Basic screen-based and walk-through models are presented. In addition, it is proposed a model for object-based manipulation which is ideal for objects which present a natural bounding box, such as geological units. A companion paper summarizes the geometric transformations which are necessary for displaying a 3D environment on a screen, and which are based on the adopted visualization parameters.
