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 \(f(d)=\frac{10}{2*d^2+5*d+10}\).

PHYSICAL = 5

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