topics

motivation / scope

0.5 weeks

• Knowledge of the functional range and basic efficient implementation strategies
• experience in modern c++ and software engineering
• effective use of modern hardware (GPU,CPU)
• basis for exotic or lean games
• NOT a good basis if you just want to make games
  • will not cover all necessary components
  • many good and complete engines available (unity, unreal, ...)
• overview of required components: rendering, physics, sound, assets, ...
