• Optimization
  

  General advice on how to optimize games

• Lossy Compression
  

  Voxels don't need to be exact values all the time, allowing for lossy compression.

• Back Face Culling
  

  Removal of geometry not facing the camera.

• Cluster Culling
  

  Efficiently culling small clusters of geometry.

• Interior Culling
  

  Removal of geometry hidden within geometry.

• Portal Culling
  

  Removal of geometry that is not in the same 'room'.

• Compression
  

  The many ways to compress volumetric data.

• Rendering: Culling
  

  In general, (visibility-) culling is the process of limiting the amount of things rendered (both geometry and drawcalls) to manageable levels, so the GPU doesn't go up in flames.

• Level Of Detail
  

  Replacement of geometry that is too small with lower detail geometry.

• Run-Length Encoding
  

  Run-Length Encoding (or RLE for short) is a type of compression that encodes sequences of repeating values in just a few bytes!

• Distance Culling
  

  Removal of geometry that is too far away.

• Palette Compression
  

  Compressing voxels like one would a GIF-image.

• Occlusion Culling
  

  Removal of geometry that is fully hidden behind other geometry.

• Frustum Culling
  

  Removal of geometry that is outside the cameras view region.
