XAML Object Element Usage
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;
}
