-
isConstant
public boolean isConstant()
- Specified by:
isConstant
in interfaceLight
- Overrides:
isConstant
in classAbstractLight

getLight
public final void getLight(double x, double y, double z, double[] L)
Computes the light vector in (x, y, z)- Parameters:
x
- x-axis coordinate where the light should be computedy
- y-axis coordinate where the light should be computedz
- z-axis coordinate where the light should be computedL
- array of length 3 where the result is stored
