Detailed Description

This node defines a directional light source that illuminates along rays parallel to a given 3-dimensional vector.

File Format/Default

DirectionalLight {
  on TRUE
  intensity 1
  color 1 1 1
  direction 0 0 -1
}

Action Behavior

SoGLRenderAction
Activates this light (if so specified) during traversal. All shape nodes that come after this light in the scene graph are illuminated by this light. The light's direction is affected by the current transformation.
