Customizing Your Model’s Background自定义模型的背景

In SketchUp, you see a tan and blue background that suggests the earth and sky. The default background might be great for buildings, but looks a little strange for a model of a rocking chair, as shown in the upper-left corner of the figure. 在SketchUp中，你会看到一个棕褐色和蓝色的背景，暗示着大地和天空。默认背景对于建筑物来说可能很好，但对于摇椅模型来说看起来有点奇怪，如图左上角所示。No matter what you’re modeling, you may just want a plain background with sketchy edges to communicate that your model is a blueprint or prototype. Or you may want a polished and detailed background that simulates an interior or a street scene.无论你在建模什么，你可能只想要一个带有粗略边缘的普通背景，以传达你的模型是蓝图或原型。或者，您可能需要一个抛光和详细的背景来模拟室内或街道场景。

Notice how the different backgrounds change the look of the model in the figure.请注意，不同的背景如何改变图中模型的外观。

So how do you customize the background of your 3D model? As with most things in SketchUp, you have a couple of options:那么，你如何定制3D模型的背景呢？与SketchUp中的大多数内容一样，您有几个选项：

• Styles: Choose from preset styles or mix your own style in the Styles panel. See Choosing a Style for details.从预设样式中选择，或在“样式”面板中混合自己的样式。有关详细信息，请参阅选择样式。
• Images: 图像：SketchUp enables you add image files to your model and position those images so that they act as a background. For example, you can have a single image placed vertically behind a house so that you can study what will be seen from certain angles within the house. SketchUp允许您将图像文件添加到模型中，并定位这些图像，使其作为背景。例如，你可以将一张照片垂直放置在房子后面，这样你就可以研究从房子里的某些角度看到的东西。A more advanced technique is applying an image as a projected texture to a curved face that you place behind a model, so you can see through more windows of an interior model. 一种更先进的技术是将图像作为投影纹理应用于放置在模型后面的曲面，这样你就可以透过内部模型的更多窗口看到。The articles you find in Applying Colors, Photos, Materials, and Textures explain the concepts and techniques you need to know in order create these image effects.您在“应用颜色、照片、材质和纹理”中找到的文章解释了创建这些图像效果所需了解的概念和技术。
