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; }
