Returns:

float[]

getIntensity

public double getIntensity()

Get this light's intensity

Returns:

double the intensity

public void setIntensity(double intensity)

Sets the intensity.

Parameters:

intensity - the intensity

isGlobal

setAmbientFake

public void setAmbientFake(boolean b)

Parameters:

global: - setting whether the light should be considered as a fake for ambient light (so sophisticated renderers might ignore it).

accept

Description copied from class: SceneGraphNode

The accept method for a SceneGraphVisitor.

Overrides:

accept in class SceneGraphNode
