Spotlight
Menu: View – Render – Light > New spotlight
Toolbar: Lights –
Command line: SPOTLIGHT
Creates focused source of light that simulates flashlight or headlight.
Spotlight is displayed in the work space as a flashlight icon with two emitted light cones. An internal cone displays borders of light of permanent brightness, external one determines borders of fade in light intensity.
Command prompts:
Set the light source location: | Define the point of the light source location. |
---|---|
Set the target location: | Define the point of the target location – the point to which the light flux will be directed. |
Enter the name of the modified mode or [Name/Intensity/Status/Photometry/Spot/Falloff/Attenuation/Color/Exit]: | Define the command options, if necessary, otherwise just press Enter. |
Command options:
Name | Name of the light source. |
---|---|
Intensity | Brightness of the light: from 0 to the maximum value supported. By default, is equal to 1. |
Status | Status of the light source: turned on/off. The disabled light source stops lighting, and its icon in the work space changes color to bright green. |
Photometry | Photometry is the measurement of the luminous intensities of visible light sources. Intensity of light in photometry is the measurement of perceived power emitted by a light source in a particular direction.
|
Hotspot | Angle of the light beam that defines the size of the inside light cone of the same brightness equal to the value of Intensity parameter. The angle value can be in the range from 0 to 160 degrees (45 by default). |
Falloff | Angle that defines the size of external cone of light (full cone of light). Internal and external cones define the area of Falloff, in which brightness from this light source falls from maximum to 0. |
Attenuation | Diminishing the light intensity (brightness) over distance from the light source. Attenuation type:
|
A8 | Color of light given by this source.
|
Exit | Exits the command. |
