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.

Level Of Detail: Level Of Detail: All the data for a certain building is classified by its level of detail. Level Of Detail: All the data for a certain building is classified by its level of detail.

Key Terminology Key Terminology LOD The basic information of a building including the ID, name, description, and location LOD The basic information of a building including the ID, name, description, and location LOD A simple VRML 3D model, using a bounding box to indicate the building (the shape for this bounding box usually is a rectangle). LOD A simple VRML 3D model, using a bounding box to indicate the building (the shape for this bounding box usually is a rectangle). LOD A simple VRML 3D model,using more detail shape to indicate the building, the shape includes rectangle, ellipse and polygon LOD 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.

Building Domain Building Domain is used to save the information about a building. The information not only including the basic information such as ID 、 name 、 the short name and so on, but also including the shapes and textures for LOD1 and LOD2 as well as the viewpoints information.
