Abstract

In this paper, we are presenting a novel approach that allows rendering of a dynamic scene in a view-dependent manner. We shall refer to such scene as a view-dependent scene. View-dependence scene is a scene graph which stores the objects of the scene in a hierarchical structure. The objects are stored in the leaves of the graph in a form of view-dependence trees. Our approach does not only allow objects to change position and orientation with respect to each other, but it also allow the change of resolution based on the speed of motion of each individual object. To support level-of-detail rendering of objects in motion, we have developed an algorithm that determines the appropriate level-of-detail for objects in motion based on the degree of blurriness of the rendered images of these objects.
