Package org.web3d.x3d.sai.Lighting

Interface PointLight

All Superinterfaces:
X3DChildNode, X3DLightNode, X3DNode
All Known Implementing Classes:
PointLight
public interface PointLight 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] PointLight is a single light source that illuminates outwards in all directions. 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).
