A [[../Math/Point|Point]] [[Electromagnetic Radiation|Light]] is a type of light emitter from a specified position in same that emits light uniformly from all directions. $\huge I_{p} = (r_{a}, g_{a}, b_{a}) $ This is considered a local light source from a measurable [[../Math/Distance|distance]]. $\huge \alpha = \frac{1}{r^{2}} $ This light [[Distance Attenuation|attenuates]] inverse proportionally to the [[../Math/Distance]] inverserse proportionally to the [[../Math/Distance|distance]]. ## Shadows Because this light comes from a specific direction, this can cast [[Shadow|shadows]].
