As hard-point light sources, however, LEDs have several significant limitations in edge-lit digital displays.
2.
The Inverse-Square Law describes the predictable way a point light source radiates and changes in intensity with distance.
3.
:: : The other problem with CFLs is that they do not generate a point light source, which makes it difficult to focus them.

6.
The second shader is a so-called " fragment shader " and implements the Blinn Phong shading model in order to determine the diffuse and specular light from a point light source.
7.
However, if designing illumination from many point light sources, like light bulbs, of known approximate omnidirectionally-uniform intensities, the contributions to illuminance from incoherent light being additive, it is mathematically estimated as follows.
8.
The "'candela "'( or; symbol : "'cd "') is the SI base unit of luminous intensity; that is, luminous power per unit solid angle emitted by a point light source in a particular direction.
9.
The orange peel meter uses a laser point light source to illuminate the specimen at a 60?angle and uses a detector to measure the reflected light intensity at the equal but opposite angle.
10.
Photographic light sources are not point light sources so the law does not strictly apply but it explains why distance of artificial sources affects the character of lighting and lighting strategies in ways not seen in nature.
