Virtual reality technology Applied in the Digital Museum System
Abstract
With the development of virtual reality technology, through the computer network to demonstrate, the advantage of digital museum has gradually shown up, and the digital museum solves the preservation and management problems of heritages existed in the traditional museum. This paper introduces the Digital Museum's basic theory, construction goals and research contents, and analyzes the digital museum's core function, and based on virtual reality technology, it achieved digital networking and personalized display process of the museum heritage collection. Firstly, design and model for digital museum gallery site layout, the external space modeling, internal spatial composition, color and material etc. on 3Ds MAX platform, secondly, construct various three-dimensional objects for inserting into the previous finished construction of the gallery site, in the way, the construction of the gallery is completed. Finally after setting compatible with the viewpoint of the cameras, the browser with Cortvrml plug-in can view the scene as a whole and implement the virtual roaming. In the entire process, virtual reality technology reflects the strong real-time, simulation, interaction and flexibility. The Digital Museum of free roaming and automatic Panoramic roaming through controlling mouse show that the achievements of digital museum transcend time and space constraints and the virtual reality technology has a wide prospects in the architectural field.
