Abstract :
As the demand for virtual reality systems increases, a new approach is needed to meet the following requirements: a world consists of a large number of objects; a camera is allowed to move and a world should be displayed in near real-time depending on the position of the camera as well as the angle of its lens; and minimum effort should be needed when objects are moving. We satisfy these requirements with the following: an object-oriented rendering approach is developed; and an approach based on spatial indexing (specifically R+-tree) is developed to manage operations on objects (i.e., retrieval, insertion and deletion) effectively
