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


SoSFVec3f direction
Illumination direction vector.


Creates a directional light source node with default settings.

static SoType getClassTypeId()
Returns type identifier for this class.

Action Behavior

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.

File Format/Defaults

DirectionalLight {
intensity	1
color	1 1 1
direction	0 0 -1
