PointLight

PointLight ⟵ Light ⟵ Object3D

A light that gets emitted from a single point in all directions.
PointLight simulates light from a local source, such as a lightbulb or candle. Light rays radiate outward from a specific 3D position, creating realistic lighting with distance-based attenuation.

Methods

PointLight(const Color& color, f32 lightIntensity, f32 lightDistance, f32 lightDecay)

Universal constructor - covers all cases with smart defaults

color	RGBA color value	0xFFFFFFFF
lightIntensity	Light intensity value (0.0 - 1.0)	1.0f
lightDistance	Maximum range of the light (0 = no limit)	0.0f
lightDecay	The amount the light dims along distance	2.0f

virtual void apply() override

Applies this point light's settings to the GX pipeline

virtual void update() override

Updates the point light (called each frame)

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

Copies properties from another Object3D

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

virtual PointLight* clone() const override

Creates a copy of this light

virtual Object3D* clone(bool recursive) const override

Creates a copy of this object

recursive

Whether to clone all child objects as well

true

void setDistance(f32 newDistance)

Sets the light distance and triggers attenuation recalculation

newDistance

New distance value

void setDecay(f32 newDecay)

Sets the light decay and triggers attenuation recalculation

newDecay

New decay value

Properties

attenuationK0	f32	Constant attenuation
attenuationK1	f32	Linear attenuation
attenuationK2	f32	Quadratic attenuation
decay	f32	Light decay factor (default 2.0)
distance	f32	Maximum range of the light (0 = no limit)
gxLightObj	GXLightObj	GX light object for this point light
