Maybe
A light source that radiates light equally in all directions away from itself.
The location of the light
source is a single point in space. The light affects {@code Shape3D}s in its
{@code scope}. Any
pixels in the light's {@code range} that belong to a {@code Shape3D} will be
illuminated by it according to the
computation specified in {@link PhongMaterial}.
The docs of `PhongMaterial` will need need to be updated too.
