Several different types of representations and ways for using them have been presented, which are classified and discussed here. Furthermore, the overview includes techniques for accelerating the rendering of static scenes or scenes with animations and/or dynamic lighting effects. The advantages and drawbacks of the different approaches are illuminated, and unsolved problems and roads for further research are shown.10.2312/egst.200510421-20
