Names[edit | edit source]

  • bump mapping
  • normal mapping
  • slope[1]

Description[edit | edit source]

  • "bump mapping. It allows fake-3D visualization of subtle details previously hidden by the slow gradients in the palette." Botond Kósa[2]
  • Normal map: "Fine scale relief on flat surfaces can be visible with proper lighting. " Arnaud Cheritat[3]
  • unity3d : ParameterNormalMap
  • "Slopes rendering is originally a screen-space post-processing effect, using differences between neighbouring pixels' smooth iteration counts. More recently it can use directional distance estimate (normalized by pixel spacing) instead, which I think gerrit proved is equivalent in the limit of infinitely fine pixel grid." Claude Heiland-Allen
