Creates a distant light.
The following prompts are displayed.
Specifies the direction of the distant light with two points, a point to start from and a second point to go toward. The Vector option provides a method to specify the coordinates that represent the vector direction of the light. For example, the default value of the vector coordinates 0.0000,-0.0100,1.0000, points the light approximately in the positive Z-axis direction.
The prompts that follow depend on whether photometric units are being used, or whether standard (generic) lighting is used, which is controlled by the of the LIGHTINGUNITS system variable.
Specifies the name of the light. You can use uppercase and lowercase letters, numbers, spaces, hyphens (-), and underscores (_) in the name. The maximum length is 256 characters.
Sets the intensity or brightness of the light. The range is 0.00 to the maximum value that is supported by your system.
Turns the light on and off. If lighting is not enabled in the drawing, this setting has no effect.
The Photometry option 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 is the perceived power emitted in all directions. Luminance is the total luminous flux incident on a surface, per unit area.
Enter an intensity value in candelas, the perceived power in a luminous flux value, or illuminance value for the total luminous flux incident on a surface.
Enter f to specify the perceived power in a luminous flux value.
If you enter i, you can specify the intensity of the light based on an illuminance value.
The illuminance value can be specified in either lux or foot-candles. Enter d to specify a distance to use to calculate illuminance.
Specify the color of the light based on a color name or a Kelvin temperature. Enter ? to display a list of color names.
Enter a text string using wild card characters to display a partial listing of color names, or an asterick (*) to display all the possible choices.
If you enter k, you can specify the color of the light based on a Kelvin temperature value.
Makes the light cast shadows.
Turns off the display and calculation of shadows for the light. Turning shadows off increases performance.
Displays shadows with sharp edges. Use this option to increase performance.
Displays realistic shadows with soft edges.
Specifies the amount of memory that should be used to calculate the shadow map.
Specifies the softness to use to calculate the shadow map.
Controls the color of the light.
Specifies a True Color. Enter in the format R,G,B (red, green, blue).
Specifies an ACI (AutoCAD Color Index) color.
Specifies an HSL (hue, saturation, luminance) color.
Specifies a color from a color book.
