                         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.",
