Public Member Functions inherited from SystemEx.Drawing.Light
	Light (Vec3f position, Vec3f direction, ColorR8G8B8 ambient, ColorR8G8B8 diffuse)
void	SetProjParams (Projection projection)
	Sets the projection parameters for lights that require a frustum (typically spot lights or shadow-casting lights).

Protected Attributes
Vec4f	m_Attenuation
	Attenuation parameters for the point light. Usually encoded as (constant, linear, quadratic, range).
Protected Attributes inherited from SystemEx.Drawing.Light
Vec3f	m_Position
	World-space position of the light.
Vec3f	m_Direction
	Normalized world-space direction of the light. Used for directional and spot lights.
Vec3f	m_Up
ColorHSV	m_DiffuseColor
	Diffuse color contribution of the light. Defines the main visible light color.
ColorHSV	m_AmbientColor
	Ambient color contribution of the light. Used for low-frequency indirect lighting.

Properties
float	Brightness [get, set]
	Constant attenuation term. Controls base brightness independent of distance.
float	BrightnessFalloff [get, set]
	Brightness falloff proportional to distance. Higher values reduce brightness faster as the viewer moves away.
float	BrightnessDistance [get, set]
	Brightness falloff proportional to the square of the distance. Controls how quickly the light fades at long ranges.
float	Range [get, set]
	Maximum effective range of the light. Used for culling and optional shader optimization.

Attenuation parameters for the point light. Usually encoded as (constant, linear, quadratic, range).

Property Documentation

Brightness

float SystemEx.Drawing.PointLight.Brightness

getset

Constant attenuation term. Controls base brightness independent of distance.

                                {
            get => m_Attenuation.X;
            set => m_Attenuation.X = value;
        }

BrightnessDistance

float SystemEx.Drawing.PointLight.BrightnessDistance

getset

Brightness falloff proportional to the square of the distance. Controls how quickly the light fades at long ranges.

                                        {
            get => m_Attenuation.Z;
            set => m_Attenuation.Z = value;
        }

BrightnessFalloff

float SystemEx.Drawing.PointLight.BrightnessFalloff

getset

Brightness falloff proportional to distance. Higher values reduce brightness faster as the viewer moves away.

                                       {
            get => m_Attenuation.Y;
            set => m_Attenuation.Y = value;
        }

Range

float SystemEx.Drawing.PointLight.Range

getset

Maximum effective range of the light. Used for culling and optional shader optimization.

                           {
            get => m_Attenuation.W;
            set => m_Attenuation.W = value;
        }
