Abstract
This paper addresses three research issues for the virtual heritage system: 3D mode ling, 3D media asset database management, and Interactive presentation through networks. We first show an overview of our virtual heritage system and introduce our approaches on each research issue. We develop 3D modeling environment using both of two emerging techniques, Le. image-based 3D mode ling and 3D laser scanning-based 3D modeling techniques. Each technique captures range data of 3D objects using 3D input devices and uses 3D mesh mode ling scheme. Our test results from both of these trials are shown. One of the important tasks for the virtual heritage system is: 1. How to manage the various kinds of cultural heritage assets. For this goal, our approach for an asset management is described. This includes the system configuration and asset creation method. 2. How electronic technology converts virtual to reality. 3. Electronic technology is in continuous development and it became able to convert Hypothesis to virtual reality in Architecture, especially in heritage where architectures became able to register monuments for saving or restoration of heritage especially in 3D field by using 3D Laser Scanner and this help humanity cause it increase the economic due to tourism. 4. Electronic technology takes part in sustainability.
