Defines the light type in calls to methods such as setLight and getLight.

Fields

attenuation0

Constant light intensity. Specifies a light level that does not decrease between the light and the cutoff point given by the range field.

attenuation1

Light intensity that decreases linearly. The light intensity is 50 percent of this value halfway between the light and the cutoff point given by the range field.

attenuation2

Light intensity that decreases according to a quadratic attenuation factor.

colorA

the alpha element of the color of the light.

colorB

The blue element of the color of the light.

colorG

The green element of the color of the light.

colorR

The red element of the color of the light.

directionx

The x axis element of the direction of the light in world space.

directiony

The y axis element of the direction of the light in world space.

directionz

The z axis element of the direction of the light in world space.

dltType

Type of the light source. This is one value of light type.

falloff

Decrease in illumination between the umbra (the angle specified by the theta field) and the outer edge of the penumbra (the angle specified by the phi field).

phi

Angle, in radians, defining the outer edge of the spotlight's penumbra. Points outside this cone are not lit by the spotlight.

positionx

The x axis element of the position of the light in world space.

positiony

The y axis element of the position of the light in world space.

positionz

The z axis element of the position of the light in world space.

range

Distance beyond which the light has no effect.

theta

Angle, in radians, of the spotlight's umbra—that is, the fully illuminated spotlight cone.
