Design & Implementation

• Tools Used
  VRML2.0 used during the process of development and you can use CosmoPlayer 2.1 plug-in for viewing the simulator.

• Road Design
  
  

    Using simple flat faces (IndexedFaceSet node) which consumes minimum number of polygon faces.

• Building Design
  

  Buildings in VRML created using the Box geometry type and then applying mapping technique. p55

• Models Design
  

   

• User Interaction & Object Behaviour Design
  Here we describe the following:
  - The way the user navigates in the world.
  - The way the objects are animated in the world.
  - The things which happen according to the user location.
  In VRML world the user is represented by what is called an avatar, which is simply an embodiment of the user in the 3D world. The
  avatar characteristics are defined in the NavigationInfo node. The collision detection used is the default provided by VRML. VRML
  provides ProximitySensor node to achieve the chase maneuvers.
