Class TCastlePointLight

Unit

Declaration

type TCastlePointLight = class(TCastlePunctualLight)

Description

Point light is a point in 3D space that shines uniformly in all directions. The rotation of this transformation doesn't matter.

See X3D PointLight specification for various details.

Properties

Public property Color: TCastleColorRGB read FColor write SetColor;

Light color shining over surface. By default white.

Public property Attenuation: TVector3 read FAttenuation write SetAttenuation;

Attenuation determines how quickly light intensity falls off with distance. By default Vector3(0, 0, 1), which means light falls off according to inverse square law.

Published property Intensity: Single read FIntensity write SetIntensity default 1.0;

Intensity, multiplied by color. Can be anything >= 0.

Published property Radius: Single read FRadius write SetRadius default DefaultRadius;

Light doesn't shine at all outside of a sphere with this radius. For performance reasons, set this as small as possible, to avoid even considering this light at further shapes. Set to -1 to have no limit.

Published property ColorPersistent: TCastleColorRGBPersistent read FColorPersistent ;

Color that can be visually edited in Castle Game Engine Editor, Lazarus and Delphi. Normal user code does not need to deal with this, instead read or write Color directly.
