All Superinterfaces:: X3DChildNode, X3DLightNode, X3DNode

All Known Implementing Classes:: SpotLight

public interface SpotLight extends X3DLightNode

Linear attenuation may occur at level 2, full support at level 3.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. 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. *

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
