PointLight Class

Represents a light source that has a specified position in space and projects its light in all directions.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

public sealed class PointLight : PointLightBase
<PointLight .../>

The rate at which the light's intensity diminishes over distance is called its attenuation and can be controlled by setting the ConstantAttenuation, LinearAttenuation, or QuadraticAttenuation properties.

The following examples create a PointLight object and set some of its properties.

// Point light values.
PointLight _ptLight = new PointLight();
public MyLights()
    for (int i = 0; i < nbrDirLights; i++)
        _dirLight[i] = new DirectionalLight();
        _dirLight[i].Color = _dirLightColor[i];
        _dirLight[i].Direction = _dirVector[i];

    _ptLight.Position = new Point3D(-3, -7, 10);
    _ptLight.Color = System.Windows.Media.Brushes.White.Color;
    _ptLight.Range = 15.0;
    _ptLight.ConstantAttenuation = 3.0;
