Class PointLight

java.lang.Object

de.jreality.scene.SceneGraphNode

de.jreality.scene.Light

de.jreality.scene.PointLight

Direct Known Subclasses:

SpotLight

public class PointLight
extends Light

A point light class. Situated at the origin (0,0,0,1); use scene graph transformations to position it where you want.

The attenuation of the point light is proportional to 1/(A0+A1*d+A2*d*d) where d is the distant of the illuminated point from the light. Set these attenuation factors using setFalloff(double, double, double).

TODO: Somebody needs to document what the shadow map settings are for.
