摘      要：As the demand for virtual reality systems increases, a new approach is needed to satisfy the following requirements: 1) A world consists of a large number of objects;2) 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 3) Minimum effort should be needed when objects are moving. We satisfy these requirements with the following: 1) An object-oriented rendering approach is developed and 2) An approach based on region trees and spatial indexing (specifically R+-tree) is developed to manage operations to objects (i.e., retrieval, insertion, and deletion) effectively.
