Light

Abstract base class for all light types.

This class is not intended to be used directly. Use one of the concrete light types such as AmbientLight, DirectionalLight, PointLight, or SpotLight.

INFO

Derives from Node and inherits all public properties and methods.

Construction

Constructors

Light()

Constructs a new light.

Light::Light(Color color, float intensity);

Parameter	Description
color	Light color.
intensity	Light intensity multiplier.

Types

Light::Type enum

Enumerates all supported light types.

Value	Description
Ambient	Non-directional constant light.
Directional	Infinitely distant light with parallel rays.
Point	Omnidirectional light emitting from a single point.
Spot	Light emitting in a cone from a single point.

Properties

color Color

Light color represented as RGB components.

Color color {0xffffff};

intensity float

Intensity multiplier applied to color.

float intensity {1.0f};

Functions

GetNodeType() Node::Type virtual

Identifies this node as Node::Type::Light.

Type vglx::Light::GetNodeType() const override;

GetType() Light::Type pure virtual

Returns the specific Type of this light.

virtual Type vglx::Light::GetType() const=0;

SetDebugMode() void virtual

Enables or disables debug visualization mode.

This mode can be used by renderers to draw light representations such as frustums, spheres, or cones for debugging purposes.

virtual void Light::SetDebugMode(bool is_debug_mode);

Parameter	Description
is_debug_mode	true to enable debug mode; false to disable.
