Defines the emission color that is applied to all CAD surfaces. This series of values represents the RGB color values for the diffused light. The first three numbers represent the RGB values respectively. The numbers are somewhere between 0.0000 and 1.0000. 0.0 0.0 0.0 represents Black, while 1.0 1.0 1.0 represents White. The last number is always set to 1.0.
Entry Name: Material_Emission
Entry Type: Character String that specifies the RGB color Intensities. The default value is 0.0000 0.0000 0.0000 1.0 (Black).
Materials may have an emissive color, which simulates light originating from an object. In the OpenGL lighting model, the emissive color of a surface adds intensity to the object, but is unaffected by any light sources. Also, the emissive color does not introduce any additional light into the overall scene.
