Description

Fields

AmbientColor: TFloatColor;

Ambient color emitted by the light.

DiffuseColor: TFloatColor;

Diffuse color emitted by the light.
This is the primary color you want to set.

SpecularColor: TFloatColor;

Specular color emitted by the light.
For details how to use specular highlights, see TMaterial.Shininess.

Attenuation: TVector3D;

Attenuation factors (constant, linear, quadratic).
Changes the light strength fading over distance. Can also be altered by setting the radius, Attenuation will change to (0,1.f/radius,0). Can be overridden after radius was set.

OuterCone: Single;

The angle of the spot's outer cone. Ignored for other lights.

InnerCone: Single;

The angle of the spot's inner cone. Ignored for other lights.

Falloff: Single;

The light strength's decrease between Outer and Inner cone.

Position: TVector3D;

Read-ONLY! Position of the light.
If Type is ltDirectional, it is ignored. Changed via light scene node's position.

Direction: TVector3D;

Read-ONLY! Direction of the light.
If Type is ltPoint, it is ignored. Changed via light scene node's rotation.

Radius: Single;

Read-ONLY! Radius of light. Everything within this radius be be lighted.

LightType: TLightType;

Read-ONLY! Type of the light. Default: ltPoint.

CastShadows: Boolean;

* Read-ONLY! Does the light cast shadows?
