List of Prompts
The following prompts are displayed.
Specify source location <0,0,0>: Enter coordinate values or use the
pointing device
Specify target location <0,0,-10>: Enter coordinate values or use the
pointing device
If the LIGHTINGUNITS system variable is set to 0, the following prompt is
displayed:
Enter an option to change [
Name (page ?)/Intensity (page
?)/
Status (page ?)/shadoW (page ?)/Attenuation (page
?)/
Color (page ?)/eXit (page ?)] <eXit>:
If the LIGHTINGUNITS system variable is set to 1 or 2, the following prompt
is displayed:
Enter an option to change [
Name (page ?)/Intensity factor
(page ?)/Status (page ?)/Photometry (page ?)/shadoW (page
?)/
Attenuation (page ?)/filterColor (page ?)/eXit (page
?)] <eXit>:
NOTE
When the LIGHTINGUNITS system variable is set to 1 or 2, the Attenuation
option has no affect on the creation of the light. It is only maintained for
scripting compatibility.
Name
Specifies the name of the light.
Intensity/Intensity Factor
Sets the intensity or brightness of the light.
Status
Turns the light on and off.
Photometry
Photometry is available when the LIGHTINGUNITS system variable is set to
1 or 2. Photometry is the measurement of the luminous intensities of visible
light sources.
In photometry, luminous intensity is a measure of the perceived power emitted
by a light source in a particular direction. Luminous flux is the perceived
power per unit of solid angle. The total luminous flux for a lamp is the
perceived power emitted in all directions. Luminance is the total luminous
flux incident on a surface, per unit area.
