示例

以下摘录显示了 MaterialGroupThe following excerpt shows a MaterialGroup.

<MaterialGroup x:Key="LeavesMaterial1">
  <DiffuseMaterial>
    <DiffuseMaterial.Brush>
      <ImageBrush Stretch="UniformToFill" ImageSource="sample_images\leaves_closeup.png" TileMode="None" ViewportUnits="Absolute" Viewport="0 0 1 1" AlignmentX="Left" AlignmentY="Top" Opacity="1.000000" />
    </DiffuseMaterial.Brush>
  </DiffuseMaterial>
  <SpecularMaterial SpecularPower="85.3333">
    <SpecularMaterial.Brush>
      <SolidColorBrush Color="#FFFFFF" Opacity="1.000000"/>
    </SpecularMaterial.Brush>
  </SpecularMaterial>
</MaterialGroup>

注解

由于 DiffuseMaterialSpecularMaterialEmissiveMaterial 提供了不同的效果,因此组合它们会很有用。Because DiffuseMaterial, SpecularMaterial, and EmissiveMaterial provide distinctly different effects, it's useful to combine them. 例如,可以选择使用 DiffuseMaterial 将复杂纹理应用到网格,同时使用同一网格上的 SpecularMaterial 添加突出显示效果。For example, you might choose to apply a complex texture to a mesh using DiffuseMaterial, while adding a highlighting effect with a SpecularMaterial on the same mesh. MaterialGroup 允许将这些材料视为单个纹理以方便使用。MaterialGroup allows you to treat these Materials as a single texture for convenience.
