5.6.1 Point Lights

This is the most basic light source. It sends light of a given color C from a point S in space uniformly in all directions:

  light_source { S, rgb C }

The color can be specified by the keyword rgb and a 3d-vector $ C=\langle R,G,B\rangle$ with red($ =R$), green($ =G$) and blue($ =B$) component.
