3. VRML Why we are choose VRML Why we are choose VRML The Virtual Reality Modeling Language is a file format for describing 3D interactive worlds and objects. It can be used in conjunction with the World Wide Web to create three-dimensional representations of complex scenes.

5. Key Terminology Key Terminology LOD0 ---- The basic information of a building including the ID, name, description, and location LOD0 ---- The basic information of a building including the ID, name, description, and location LOD1 ---- A simple VRML 3D model, using a bounding box to indicate the building (the shape for this bounding box usually is a rectangle). LOD1 ---- A simple VRML 3D model, using a bounding box to indicate the building (the shape for this bounding box usually is a rectangle). LOD2 ---- A simple VRML 3D model,using more detail shape to indicate the building, the shape includes rectangle, ellipse and polygon LOD2 ---- A simple VRML 3D model,using more detail shape to indicate the building, the shape includes rectangle, ellipse and polygon LOD3 --- user can input external high level of detail VRML 3D model to the Campus3D system and pictures about the outside of building. LOD3 --- user can input external high level of detail VRML 3D model to the Campus3D system and pictures about the outside of building. LOD4 --- Including LOD3 data and the pictures about the inside of building. LOD4 --- Including LOD3 data and the pictures about the inside of building.
