Virtual Reality has to balance the visual quality against performance since there are usually physical performance limitations in any VR gear. Explore methods to improve performance and optimize a VR app.

WHAT YOU WILL LEARN

  • Describe why optimization is fundamental for a user to have a good vr experience
    Use the unity profiler to find areas that need optimization
    Use the unity frame debugger to investigate rendering issues and find objects that don't need to be rendered
    Optimize the drawing of objects by removing faces of any object that will not be seen
    Find objects that are being overdrawn and remove them to reduce wasting gpu time
    Use occlusion culling to prevent rendering of objects that are not visible
  • Use draw call batching to batch draw calls to improve performance
    Eliminate or reduce the lighting requirements to increase performance
    Use shaders only where appropriate to increase performance
    Use the built-in quality settings to balance the visual quality versus performance of the app
    Adjust the level of detail (lod) setting to reduce the number of rendered triangles as objects get farther away
    Describe why optimization is required for vr apps and describe some of the techniques that can be used
