Optimalisation

Goal

The aim of this module is to provide an introduction to some of the optimisation techniques that are commonly applied to virtual environments in order to improve performance.

Contents

• Optimisation
  • Minimising lag

  • Culling algorithms
  • Managing the scene
  • Polygon reduction
  • Level of detail
  • Mathematical representations
  • Billboards
  • Optimisation Tools
• Implementing scene optimisation techniques using jMonkeyEngine 3
