Glow

Glow[col]
is a graphics directive which specifies that surfaces of 3D graphics objects which follow are to be taken to glow with color col.

Glow[]
specifies that there is no glow.

Glow is added to diffuse and specular reflection components to determine the final rendered color of a surface.

A surface can be specified as having an absolute color col by giving the combination of directives Glow[col], Black and Specularity[0].

Cylinder that glows red, but has a black surface that reflects no light:

Glow gives overall surface color that is independent of any Lighting:

Other surface colors still interact with lighting even if Glow is given:

Use a pure color function with no lighting interaction:

Use a color function based on the phase of a complex function:

With Glow, objects can look flat if edges are not drawn:
