What is Virtual Reality?

[ Previous | Index | Next ]


Software

  • Need modelling tools to create objects
    • AutoCAD, 3D Studio Max, MultiGen II, etc.
    • Designing objects is time-consuming
    • Objects often need to be optimised for VR use
    • In some cases (eg scientific visualisation) the objects might be generated by software -- need to provide equations and data to define objects

  • To define an interactive virtual environment:
    • Import objects (models)
    • Define behaviour of objects
    • Define motion and interaction model

  • Typical Run-time Components
    • Real-time visual/audio rendering engine
    • Input/Output handling process
    • Simulation process
    • World database (objects and scripts that define virtual environment)
