Places point lights.
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.
- Glyph for a point light illuminating in all directions.
- 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
- Specifies a name for the light so that it can be identified by the LightList command.
- Intensity factor
- Specifies the intensity of the light.
- Toggles the use of this light.
- Specifies the photometric properties of the light.
- Sets the intensity expressed in candela.
- Sets the luminous flux expressed in lumens.
- Sets the illuminance expressed in lux or foot-candles.
- Sets a distance expressed in drawing units.
- Sets the color.
- Lists the names of available colors.
- Sets a color temperature expressed in degrees Kelvin.
- Specifies the look of shadows cast by this light.
- Disables the calculation of shadows for the light.
- 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.
- Sets the shape of the light.
- Sets the radius of the disk.
- Sets the length and width of the rectangle.
- Specifies the sampling size of the shadow.
Note: Larger numbers are more accurate but take longer to render.
- Toggles the shape visibility.
- Specifies how the illumination falls off with distance from the light.
- attenuation Type
- Specifies the type of attenuation.
- 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.
- Specifies the color of the light.
- Index color
- Specifies an Index color.
- Specifies the color using three parameters Hue, Saturation and Lightness.
- Specifies a bookcolor name.
