The DirectionalLight node defines a directional light source that illuminates along rays parallel to a given 3-dimensional vector. A description of the ambientIntensity, color, intensity, and on fields is in 4.6.6, Light sources.
The direction field specifies the direction vector of the illumination emanating from the light source in the local coordinate system. Light is emitted along parallel rays from an infinite distance away. A directional light source illuminates only the objects in its enclosing parent group. The light may illuminate everything within this coordinate system, including all children and descendants of its parent group. The accumulated transformations of the parent nodes affect the light.
DirectionalLight nodes do not attenuate with distance. A precise description of VRML's lighting equations is contained in 4.14, Lighting model.

Construct a node with all its fields set to default value, which is equivalent to the code below: ambientIntensity = 0; color.setRGB(1,1,1); direction.setXYZ(0,0,-1); intensity = 1; on = true; |
