PointLight

Represents light emanating from a point source, attenuated across a distance.

Attenuation for the light source is controlled by a constant factor, a linear factor, and a quadratic factor. For best results, the three should add up to 1.0.

origin: the location of the point light, in world coordinates
attenuateConst: the constant attenuation factor
attenuateLin: the linear attenuation factor
attenuateQuad: the quadratic attenuation factor

Calculates the vector of the ray of light that reaches a point.
Calculates the vector of the ray of light that reaches a point. The length of the vector is the intensity of the light. The direction of the vector is the direction from the light to the point.
pt
the point to illuminate
returns
the light ray
