1.4.1.2 How do I make bright objects?

"How do I make bright objects, which look like they are emitting light?"

There is a simple trick to achieve this: Set the ambient value of the object to 1 or higher. This makes POV-Ray to add a very bright illumination value to the object so the color of the object is in practice taken as is, without darkening it due to shadows and shading. This results in an object which seems to glow light by itself even if it is in full darkness (useful to make visible light sources, or small lights like leds which do not cast any considerable light to their surroundings but can be easily seen even in the darkness).

A more sophisticated method would be using an emitting media inside the object (and making the object itself transparent or semi-transparent).
