SceneLightingEffect 类

定义

命名空间:

Microsoft.UI.Composition.Effects

控制 SpriteVisual 的反射属性。 SceneLightingEffect 将覆盖 CompositionLight 默认值。 它用于控制 SpriteVisual 的反射属性。 NormalMap 可用作输入源，但不是必需的。

示例

IGraphicsEffect graphicsEffect = new CompositeEffect() 
{ 
  Mode = CanvasComposite.Add, 
  Sources = 
  { 
    new CompositionEffectSourceParameter("ImageSource"), 
    new SceneLightingEffect() 
    { 
      Name = "Material",                                     
      AmbientAmount = 0, 
      DiffuseAmount = .75f, 
      SpecularAmount = 0, 
      SpecularShine = 20 
      NormalMapSource = new CompositionEffectSourceParameter("NormalMap"), 
    } 
  } 
}; 

构造函数

SceneLightingEffect()

创建 SceneLightingEffect 的实例。

属性

AmbientAmount	效果使用的预定义 AmbientLight 的比例。
DiffuseAmount	漫射光的强度。
Name	灯的名称。
NormalMapSource	效果的法线映射。
ReflectanceModel	获取或设置一个值，该值指示如何建模 SceneLightingEffect 的反射率。
SpecularAmount	反射光的强度。
SpecularShine	Blinn-Phong照明模型的反射功率。
