DriveWorks Pro 16: Directional Light [send feedback...]

Directional Light

The Directional Light entity lights an entire 3D scene evenly from one direction. This entity adds a Directional Light to the node it is applied to.

A directional light can be thought of as a distant light source which lights the entire scene. It behaves in many ways like the sun.

A directional light does not have any identifiable source position and so the node can be placed anywhere in the scene. All objects in the scene are illuminated as if the light is always from the same direction. The distance of the light from the target object is not defined and so the light does not diminish.

Directional Lights should be used as an imaginary out of scene light source. For lights within a scene, that have been modelled, Spot Lights and Point Lights should be used.

When added to a node, the nodes position in 3D space does not affect how the light is emitted. Only the direction of the light, color and intensity matter for this entity.

With the node selected, the directional light points in the direction of the blue arrow (forward direction) on the node. You can control the direction of the light source by changing the direction of the blue arrow.

Information Panel

With the model node selected and the Directional Light entity added to the node, the following will be displayed in the Information Panel:

Color

The color will change based on the values of the properties below. Color will show you the color of the light you are creating.

Red Intensity

Red Intensity controls how much red will be in the light source. Enter a number from 0 to 1

Green Intensity

Green Intensity controls how much green will be in the light source. Enter a number from 0 to 1

Blue Intensity

Blue Intensity controls how much blue will be in the light source. Enter a number from 0 to 1

Intensity

Intensity (brightness) controls how bright the light will be. The higher the number, the brighter the light source. Enter any number in this property to change the intensity.

Parameter Panel

With the model node selected and the Directional Light entity added to the node, the following will be displayed in the Parameter Panel:

  • Intensity

    Intensity (brightness) controls how bright the light will be. The higher the number, the brighter the light source. Enter any number in this property to change the intensity.

  • Red Intensity

    Red Intensity controls how much red will be in the light source. Enter a number from 0 to 1

  • Green Intensity

    Green Intensity controls how much green will be in the light source. Enter a number from 0 to 1

  • Blue Intensity

    Blue Intensity controls how much blue will be in the light source. Enter a number from 0 to 1
