DirectionalLight

DirectionalLight ⟵ Light ⟵ Object3D

A light that gets emitted in a specific direction.
DirectionalLight simulates light from an infinitely distant source, such as the sun. All light rays produced are parallel, making it perfect for simulating daylight or distant light sources.

Methods

DirectionalLight(const Color& color, f32 lightIntensity)

Universal constructor - covers all cases with smart defaults

color	color (RGBA)	Color()
lightIntensity	Intensity value (0.0 - 1.0)	1.0f

virtual void apply() override

Applies this directional light's settings to the GX pipeline

virtual void update() override

Updates directional light state (called each frame)

virtual DirectionalLight* clone() const override

Creates a copy of this directional light

virtual void copy(const Light& source) override

Copies properties from another light

source

Source light to copy from

virtual void copy(const Object3D& object, bool recursive = true) override

Copies properties from another Object3D

object	Source object to copy from
recursive	Whether to copy all child objects as well

virtual Object3D* clone(bool recursive = true) const override

Creates a copy of this object

recursive

Whether to clone all child objects as well

Properties
