HemisphericAmbientLight Class

Immutable class that represents hemispheric ambient lighting. The color of a face is determined by its normal. If the normal points in the direction of the member DirectionBelowToAbove, the color is ColorAbove. If the normal points in the opposite direction, the color is ColorBelow. The color for all other directions is an interpolated value between ColorBelow and ColorAbove.

Properties
 NameDescription
Public propertyColorAbove Gets the color of the face if its normal vector points in the same direction as DirectionBelowToAbove.
Public propertyColorBelow Gets the color of the face if its normal vector points in the direction opposite to DirectionBelowToAbove.
Public propertyDirectionBelowToAbove Gets the direction from "below" to "above".
Public propertyIsAffixedToCamera Gets a value indicating whether this light source is affixed to the camera coordinate system or to the world coordinate system.
Public propertyLightAmplitude Gets the light amplitude. The default value is 1. This value is multiplied with the light colors (ColorBelow and ColorAbove) to get the effective light's color.
