Detailed Description

Class representing a Point Light.

Point lights emit light all around them, from a single point. Their light can be subject to a distance-based attenuation.

Constructor & Destructor Documentation

◆ vpPanda3DPointLight()

vpPanda3DPointLight::vpPanda3DPointLight	(	const std::string &	name,
		const vpRGBf &	color,
		const vpColVector &	position,
		const vpColVector &	attenuation )

inline

Build a new point light.

See also: vpPanda3DLight constructor.

Parameters

name	name of the light
color	color of the light
position	Position in the scene of the light. Uses ViSP coordinates.
attenuation	Attenuation components of the light as a function of distance. Should be a vector of size 3 where the first component is the constant intensity factor (no falloff), the second is a linear falloff coefficient, and the last one is the quadratic falloff component. To follow the inverse square law, set this value vector to [0, 0, 1] To have no falloff, set it to [1, 0, 0].

◆ getColor()

const vpRGBf & vpPanda3DLight::getColor ( ) const

Get the light's color.

Returns: const vpRGBf&
