LightAttenuation

class LightAttenuation

NONE = 0

No attenuation $f(d)=1$.

LINEAR_SLOW = 1

Slow linear attenuation $f(d)=\frac{2}{d+2}$.

LINEAR_FAST = 2

Fast linear attenuation $f(d)=\frac{1}{d+1}$.

QUADRATIC_SLOW = 3

Slow quadratic attenuation $f(d)=\frac{1}{d^2+d+1}$.

QUADRATIC_FAST = 4

Fast quadratic attenuation $f(d)=\frac{10}{2\ast d^2+5\ast d+10}$.

PHYSICAL = 5

Physically realistic attenuation $f(d)=\frac{1}{d^2}$.
