property double InnerConeAngle { double get(); void set(double value); };public double InnerConeAngle { get; set; }member this.InnerConeAngle : double with get, setPublic Property InnerConeAngle As Double속성 값
조명이 장면의 개체를 완전히 비추는 SpotLight의 원뿔 모양 프로젝션 비율을 지정하는 각도(도)입니다. 기본값은 180합니다.
예제
다음 예제에서는 만드는 방법을 보여 줍니다는 SpotLight 3 차원 장면에서.
<!-- A SpotLight is used to light the scene. The InnerConeAngle and OuterConeAngle are used
to control the size of the light cone created by the SpotLight. The Direction and Position
properties determine where the SpotLight is pointing in the scene. In this example, the Position
of the SpotLight is set so that the SpotLight is only illuminating the upper right-hand corner
of the 3D object. -->
