Surface direction as colour

Every point on a surface faces a direction. A normal map records that direction as a colour, so you can see the shape of the picture at a glance, or use the output as a lighting input for other effects.

Where the surface comes from

Source picks the surface: Luminance treats brightness as height, which suits a texture or a photographed relief; Depth uses the depth map, which gives the true shape of the scene.

Output shows the raw Normals colours, or Shaded, which lights the surface. The algorithm is Sobel or Scharr: Scharr is the more accurate of the two on fine detail.

Every option, from the app

Generated from the registry the app publishes, so this list is whatever the current build actually ships — not a copy of it.

  • WireframeDraw the image as a three-dimensional wire mesh, with the faces, the lines or both.
  • Z-DepthShow the front-to-back depth map itself, as false colour, contour lines or a displacement.
  • AtmosphericHazy distance: far things fade and shift colour the way air does over a long view.
