Class TCastleDirectionalLight

Unit

CastleScene

Declaration

type TCastleDirectionalLight = class(TCastlePunctualLight)

Description

Directional light shines along a direction in 3D space, simulating a light source far away (like a sun). The direction is -Z (in local coordinates), simply rotate this transformation to change the lighting direction. The position of this transformation doesn't matter for lighting calculation (though it is useful to display the light gizmo at design-time).

See X3D DirectionalLight specification for various details.
