  • A normal is a float value between 0 and 1 that often represents a percentage.
  • A normalised vector is one where all ordinates are between 0 and 1, which simplifies calculations.
  • Normal mapping is technique in which the 3D facing of texels is represented by three normal values (one per color channel).
