Distant Light.
Library: ilvbmpflt
This class allows you to model an infinitely distant light using an elevation and an azimuth.

Constructor.
Initializes a new instance of the class IlvDistantLight
.
The default azimuth and elevation are 0.0
. The default light color is white.
IlFloat IlvDistantLight::getAzimuth | ( | ) | const |
Returns the azimuth.
IlFloat IlvDistantLight::getElevation | ( | ) | const |
Returns the elevation.
Returns the vector from this instance to a given point in 3D space.
x | The x position of the point. |
y | The y position of the point. |
z | The z position of the point. |
result | An array of 3 floating point values that will hold the vector. |
Reimplemented from IlvLightSource.
void IlvDistantLight::setAzimuth | ( | IlFloat | azimuth | ) |
Sets the azimuth.
azimuth | The new azimuth. |
void IlvDistantLight::setElevation | ( | IlFloat | elevation | ) |
Sets the elevation.
elevation | The new elevation. |
