Constructor & Destructor Documentation

IlvDistantLight::IlvDistantLight	(	IlFloat	azimuth = `0.0`,
		IlFloat	elevation = `0.0`,
		IlFloat	r = `1.0`,
		IlFloat	g = `1.0`,
		IlFloat	b = `1.0`
	)

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.

void IlvDistantLight::getLightVector	(	IlFloat	x,
		IlFloat	y,
		IlFloat	z,
		IlFloat *	result
	)

virtual

Returns the vector from this instance to a given point in 3D space.

Parameters

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.
