Class SpotLightObject

java.lang.Object
org.web3d.x3d.jsail.X3DConcreteElement
org.web3d.x3d.jsail.X3DConcreteNode

All Implemented Interfaces:

public class SpotLightObject
extends X3DConcreteNode
implements SpotLight
Linear attenuation may occur at level 2, full support at level 3.

X3D node tooltip: [X3DLightNode] SpotLight is a light source that illuminates geometry within a conical beam. Lighting illuminates all geometry except lines and points. By default, light scope only illuminates peer geometry and children nodes within the scene graph hierarchy. Lights have no visible shape themselves and lighting effects continue through any intermediate geometry.
  • Hint: the bound NavigationInfo controls whether headlight is enabled on/off.

Note that SFColorObject provides a variety of color constants.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
