PointLight QML Type
Defines a point light in the scene. More...
|Import Statement:||import QtQuick3D 1.0|
The point light can be described as a sphere, emitting light with equal strength in all directions from the center of the light. This is similar to the way a light bulb emits light.
Rotating or scaling a point light does not have any effect. Moving a point light will change the position from where the light is emitted.
constantFade : real
This property is constant factor of the attenuation term of the light. The default value is 1.0.
linearFade : real
This property increases the rate at which the lighting effect dims the light in proportion to the distance to the light. The default value is 0.0 meaning the light doesn't have linear fade.
quadraticFade : real
This property increases the rate at which the lighting effect dims the light in proportion to the inverse square law. The default value is 1.0 meaning the point light fade exactly follows the inverse square law i.e. when distance to an object doubles the light intensity decreases to 1/4th.
