Description

Places point lights for use with renderings. A point light represents sources that illuminate in all directions, such as a bare lightbulb, and it so has no target.

  1. Glyph for a point light illuminating in all directions.
  2. Sphere illuminated by the point light.
Note: Unlike all other light types, point lights do not have a target or vector associated with them. Drawings can have more than one point light.

Options within the command

Name
Specifies a name for the light so that it can be identified by the LightList command.
Intensity factor
Specifies the intensity of the light.
Status
Toggles the use of this light.
Photometry
Specifies the photometric properties of the light.
Intensity
Sets the intensity expressed in candela.
Flux
Sets the luminous flux expressed in lumens.
Illuminance
Sets the illuminance expressed in lux or foot-candles.
Distance
Sets a distance expressed in drawing units.
Color
Sets the color.
?
Lists the names of available colors.
Kelvin
Sets a color temperature expressed in degrees Kelvin.
shadoW
Specifies the look of shadows cast by this light.
Off
Disables the calculation of shadows for the light.
Sharp
Displays shadows with sharp edges. Use this option to increase performance.
soFt mapped
Displays realistic shadows with soft edges.
soft sAmpled
Displays realistic shadows with softer shadows based on extended light sources.
Shape
Sets the shape of the light.
Disk
Sets the radius of the disk.
Rect
Sets the length and width of the rectangle.
sAmples
Specifies the sampling size of the shadow.
Note: Larger numbers are more accurate but take longer to render.
Visible
Toggles the shape visibility.
Attenuation
Specifies how the illumination falls off with distance from the light.
attenuation Type
Specifies the type of attenuation.
None
No attenuation so that the distance to the light source has no influence.
Inverse linear
Attenuation is the inverse of the linear distance from the light.
Note: At a distance of 2 units from the light source, light is half as strong. At a distance of 4 units, light is one quarter as strong.
inverse Squared
Attenuation is the inverse of the square of the distance from the light.
Note: At a distance of 2 units, light is one quarter as strong. At a distance of 4 units, light is one sixteenth as strong.
Use limits
Toggles whether the extent of the illumination is limited.
attenuation start Limit
Defines the point where the light starts to shine, measured from the center of the light.
attenuation End limit
Defines the point where the light stops to shine, measured from the center of the light.
filterColor
Specifies the color of the light.
Index color
Specifies an Index color.
Hsl
Specifies the color using three parameters Hue, Saturation and Lightness.
Colorbook
Specifies a bookcolor name.
