    LightSource Class
    In This Topic
    The LightSource object represents a light source in the 3D scene. It can control the light source emission characteristics, its position and direction. You add light sources to the 3D scene with the help of the LightSources collection of the GLLightModel class. The number of light sources is limited to eight in the current Microsoft OpenGL implementation. For more information on the way that OpenGL implements lighting see the "OpenGL lighting model" topic in the User's Guide.

    Public Properties
     NameDescription
    Public PropertyAmbientThe ambient color emitted by this light source.  
    Public PropertyConstantAttenuationSpecifies the constant attenuation factor for this light. For more information see the "OpenGL Lighting Model" topic in the User's Guide.  
    Public PropertyDiffuseThe diffuse color emitted by this light source.  
    Public PropertyDirectionA vector which specifies the direction of the light source.  
    Public PropertyLightSourceTypeSelects between positional and directional light source.  
    Public PropertyLinearAttenuationSpecifies the linear attenuation factor for this light. For more information see the "OpenGL Lighting Model" topic in the User's Guide.  
    Public PropertyPositionA vector which specifies the position of the light source in 3D space.  
    Public PropertyQuadraticAttenuationSpecifies the quadratic attenuation factor for this light. For more information see the "OpenGL Lighting Model" topic in the User's Guide.  
    Public PropertySpecularThe specular color emitted by this light source.  
    Public PropertySpotCutoffThe spot cutoff angle of the light source. With the help of this property you can make a positional light source act as a spot light.  
    Public PropertySpotExponentThe spot exponent specifies the intensity distribution of a spot light.
