Reducing Number of Polygons
Reduction of polygons number to be rendered in one scene is crucial for the performance
Reduction can be static or dynamic
Static reduction is achieved by decreasing the resolution
Dynamic reduction uses the Level-of-Detail feature
Dynamic reduction can is achieved in two stages:
  • by presenting the same region with different resolution levels
  • by gathering multiple regions into bigger areas
