AmbientLight

AmbientLight[col]

is a three-dimensional graphics directive that specifies the uniform ambient light of color col to use in coloring 3D surfaces.

Details

  • AmbientLight is also known as natural light.
  • AmbientLight is typically used to fill areas that do not have enough illumination by casting soft light rays in every direction.
  • AmbientLight[col] yields a uniform ambient light of color col.
  • Colors of light sources col can be defined by RGBColor, Hue or any other color specification.
  • The setting for AmbientLight affects only colors associated with diffuse and specular reflection on a 3D surface.
  • Light sources with color specifications of the form {dcol,Specularity[scol]} are effectively taken to have colors dcol for purposes of diffuse reflection, and scol for purposes of specular reflection.
  • Diffuse reflection is taken to follow Lambert's law, with light effectively scattered equally in all directions from a surface.
  • Specular reflection effectively takes light to be scattered only close to the mirror‐reflection direction, as specified in the notes for Specularity.

Basic Examples  (2)

Ambient light on surfaces:

Style a surface in a plot:

Scope  (2)

Ambient light is uniformly applied to all the surfaces in the scene:

Ambient light gives overall lighting on the scene:

Generalizations & Extensions  (2)

Predefined colored lighting:

The colored lighting is equivalent to the following explicit setting:

Predefined neutral lighting:

The neutral lighting is equivalent to the following explicit setting:

Applications  (1)

Build a scene with multiple objects and light sources:

Animate the spotlights:

Possible Issues  (1)

The default light scheme uses several colored light sources:

Set Lighting to None to turn off the default lights:
