Abstract: A dynamic loading and unloading of model files over the Internet or a local network from a repository of objects located at a URL. The model file contains all aspects of the available features of the 3-D object including 3-D geometry, texture (image), audio, text, video as well as behavior and interactivity (logic), that is the sub-components or elements of the object model file. The models include ways of representing graphic images, which include the designation of endpoints rather than each point of an image. The present invention divides the model file into the sub-components and downloads each component separately in any order. Typical model file size is from approximately 10 Kbytes to about 1.5 Mbytes. Geometry describes the physical characteristics in a 3-D file, such as the shape and size. Images consist of a texture of the geometry. The sub-components or elements are downloaded separately to form a complete 3-D model. These elements are downloaded dynamically.
