Inverse Square
Sets attenuation to be the inverse of the square of the distance from the
point light. For example, at a distance of 2 units from a point light, light is
one quarter as strong as at the point light; at a distance of 4 units, light is
one sixteenth as strong.
Modify
Temporarily closes the dialog box so you can use the pointing device to
specify a location for the light.
Enter light location < current >: Specify a point or press ENTER
None
Sets no attenuation. Objects far from the point light are as bright as objects
close to the light.
Select Color

Shadow On
Makes the point light cast shadows. The type of shadow depends on the
current renderer type and on the settings in the Shadow Options dialog
box.
Shadow Options

Show
Displays the Show Light Position dialog box, which displays the X,Y,Z
coordinate of the light’s location and target. Point lights radiate light in all
directions with no target.
Color
Uses RGB values to control the color of the point light. The color swatch shows
the current color. To define the color of light, you can select from the 255
AutoCAD Color Index (ACI) colors, true colors, and color book colors.
