Light Sources - polygon rendering and ray tracing methods

Light Sources are key parts in any ray traced scene, since without them; there would be no rays to trace. Light sources are as objects that may be placed at arbitrary positions in the scene, although in addition to the position a light source has some intensity related with it that describes the brightness and color of the light. At any rate, lighting is identified by many to be one of the most significant factors in a ray traced image. This is the location and intensity of light source which give liveliness to an image, a picture flooded along with extreme light might lose any sense of mystery you preferred it to have, while an image as is very dark will not demonstrate enough detail to maintain its viewers interested.
