Detailed Description

Point light for omni-directional lighting.

Light emanates in all directions from a point. Intensity diminishes with distance based on attenuation.

Constructor & Destructor Documentation

PointLight() [1/2]

StevEngine::Visuals::PointLight::PointLight	(	Utilities::Vector3	diffuse = Utilities::Vector3(1.0),

		float	constant = 1.0,
		float	linear = 0.02,
		float	quadratic = 0.0017 )

Create point light.

Parameters

diffuse	Diffuse light color
specular	Specular light color
constant	Constant attenuation factor
linear	Linear attenuation factor
