Abstract: One or more embodiments of the invention provide a method, apparatus, system, and article of manufacture for modifying a three-dimensional model. A composite three-dimensional model is displayed in a computer implemented solid modeling system. The composite model comprises a first primitive and a second primitive. A first face of the first primitive is selected. Once selected, a first boundary representation of the first primitive is modified using the selected first face. Thereafter, a second boundary representation of the second primitive is automatically modified based on the modification to the first boundary representation.

Abstract: The virtual reality imaging system takes a multidimensional space that contains real world objects and phenomena, be they static or dynamic in nature, and enables a user to define a point and/or a path through this multidimensional space. The apparatus then displays the view to the user that would be seen from the point and/or path through the multidimensional space. This view is filtered through user definable characteristics that refine the real world phenomena and objects to a perspective that is of interest to the user. This filtered view presents the user with a virtual view of the reality contained within this multidimensional space, which virtual reality presents data to the user of only objects, views and phenomena that are of particular interest to the user.
