Dipole

Format

Dipole // float

The probability of a surface emitting light ray according to dipole radiation pattern. The number of photons emitted in a solid angle $d\Omega$ is proportional to $\sin^2(\theta)$, where $\theta$ is the angle between the wave vector of a light ray and the normal vector of the emission surface.

Example

#Dipole
SurfEmit
Shell 1 
1.00000

The probability is 100%.
