Light source ID

Property Value

Array of 19 doubles containing the light source properties (see Remarks)

The light source ID ranges from 0 to n, where n = (the total number of light sources - 1). To get the total number of light sources, use IModelDoc2::GetLightSourceCount.

The return values for this property is the following array of 19 doubles:

[ type, Intensity, Color[3], Position[3], Direction[3], coneAngle, falloff[3], Ambient, Specular, isDisabled, SpotExponent ]

where:

• type =  an integer packed into a double that represents the light source type where valid types are taken from openGL definitions (LIGHT_EYE, LIGHT_AMBIENT, LIGHT_SPOT, LIGHT_POINT, LIGHT_DISTANT)

• Intensity = Light-source intensity (diffuseness) where values range from 0 to 1.

• Color[3] =  Light-source color in the form of an array of 3 doubles (R, G, B) where values range from 0 to 1.

• Position[3] =  Light-source position for spot lights in the form of an array of 3 doubles (X, Y, Z) in model space.

• Direction[3] = Light-source direction in the form of an array of 3 doubles (i, j, k)

• coneAngle = Light-source cone half angle in degrees where valid values are from 0 to 90 and 180.

• falloff[3] =  Light-source falloff in the form of an array of 3 doubles (Kc, Kl, Kq). These values result in changes in light intensity as the distance between the light position and the vertex change.
  
  NOTE: The falloff[3] values are not supported in SOLIDWORKS 2011 and later.
  
  The result is driven by the following equation:

 [ 1 / (Kc + D*Kl + D*D*Kq ) ]

  where:

D =  the distance.between the light's position and the vertex

Kc = constant attenuation

Kl = linear attenuation

Kq = quadratic attenuation

• Ambient = light-source ambient Intensity

• Specular = light-source specular Intensity

• isDisabled = an integer packed into a double. True means that the light is disabled and false means the light is not disabled.

• SpotExponent = spot exponent
  
  NOTE: The SpotExponent value is not supported in SOLIDWORKS 2011 and later.
