| IfcLightSource (4) | |||
| 1 | Name | OPTIONAL IfcLabel |
The name given to the light source in presentation. |
| 2 | LightColour | IfcColourRgb |
Definition from ISO/CD 10303-46:1992: Based on the current lighting model, the colour of the light to be used for shading. Definition from VRML97 - ISO/IEC 14772-1:1997: The color field specifies the spectral color properties of both the direct and ambient light emission as an RGB value. |
| 3 | AmbientIntensity | OPTIONAL IfcNormalisedRatioMeasure |
Definition from VRML97 - ISO/IEC 14772-1:1997: The ambientIntensity specifies the intensity of the ambient emission from the light. Light intensity may range from 0.0 (no light emission) to 1.0 (full intensity). |
| 4 | Intensity | OPTIONAL IfcNormalisedRatioMeasure |
Definition from VRML97 - ISO/IEC 14772-1:1997: The intensity field specifies the brightness of the direct emission from the light. Light intensity may range from 0.0 (no light emission) to 1.0 (full intensity). |
