Foreground Object

前景对象

The Foreground object could be a cockpit and instrument display, or simply a notice of copyright or authorship that you want to appear prominently in the scene.

前景对象可以是驾驶舱和仪表显示器，或者只是一个版权或作者的通知，你希望出现在场景的显著位置。

Taking the copyright example further, the color in the image you use for the copyright message would be in the shape of the actual text you wish to display. This texture would then be loaded into the Alpha channel property of a material, from where you can use either the Alpha channel itself or clip mapping to isolate and hide from rendering the background of the copyright texture.

进一步以版权为例，您用于版权消息的图像中的颜色应该是您希望显示的实际文本的形状。这个纹理会被加载到材质的 Alpha 通道属性中，在那里你可以使用 Alpha 通道本身或者剪辑映射来隔离和隐藏版权纹理的背景渲染。

To render (or show in the viewport) a foreground or background image, you may assign a textured material to a Foreground or Background object, just as you would to any other object. For transparent areas, use the Alpha channel.

要渲染(或显示在视口)前景或背景图像，你可以分配一个纹理材质的前景或背景对象，就像你会任何其他对象。对于透明区域，使用 Alpha 通道。

Foreground and background pictures can also be tiled. For this effect, use the Material tag’s settings.

前景和背景图片也可以平铺。为此效果，使用材质标签的设置。

Foreground and background pictures are scaled to the film format during rendering. Transparent sections of the background are ignored.

在渲染过程中，前景和背景图片被缩放为电影格式。背景的透明部分被忽略。

Animations and frame sequences can also be used for foreground and background pictures. In the case of a Background object (as opposed to the Foreground object), these sequences will also be displayed in the viewport.

动画和帧序列也可以用于前景和背景图片。对于背景对象(相对于前景对象) ，这些序列也将显示在视区中。
