This allows you to place a background picture in a planar view for use as a modeling aid. For example, suppose you are building a model of a car — you can load scale diagrams of the car into the top, right and front views and use the diagrams to help you model the car accurately. The picture will be zoomed automatically when you zoom the view.
这允许您在平面视图中放置背景图片，以便作为建模辅助工具使用。例如，假设您正在建立一个汽车模型ーー您可以将汽车的比例图加载到顶部、右侧和正面的视图中，并使用这些图来帮助您准确地建立汽车模型。当您放大视图时，图片将自动缩放。
图片
Click the three dots button and use the file selector that opens to choose the background picture. Any bitmap format recognized by Cinema 4D can be loaded.
单击三点按钮并使用打开的文件选择器选择背景图片。可以加载 Cinema 4D 识别的任何位图格式。
You can also place a background image via drag & drop from your computer’s desktop directly onto a viewport.
你也可以将背景图片直接从电脑桌面拖放到视口上。
展示图片
Here you can temporarily switch a background picture on or off.
这里你可以暂时打开或关闭背景图片。
模式
These modes define how the pixels of an image loaded into the background will be used to generate new pixels when the image is scaled. Next sharpens edges and Linear will blur.
这些模式定义了在缩放图像时如何使用加载到背景中的图像像素来生成新的像素。接下来锐利的边缘和线性将模糊。
Ensures that the background picture will keep its original proportions when scaled.
确保背景图片在缩放时保持其原始比例。

Here you can move or scale the background picture horizontally or vertically.
这里你可以水平或垂直地移动或缩放背景图片。
旋转[-∞ . . + ∞ ° ]
This parameter allows you to rotate the background picture.
此参数允许您旋转背景图片。
透明度[0.99% ]
Defines the transparency of the background picture.
定义背景图片的透明度。
阿尔法模式
If the background picture has an alpha channel you can use this setting to specify how the alpha channel should be evaluated.
如果背景图片有 alpha 通道，您可以使用此设置指定应如何计算 alpha 通道。
没有
The alpha channel is ignored.
阿尔法通道被忽略。
正常
Uses the alpha channel to mask (i.e. hide) parts of the picture.
使用 alpha 通道屏蔽(即隐藏)图片的部分。
倒置的
Same as Normal except swaps around which parts are masked and which are displayed.
与普通交换相同，只是交换的部分被屏蔽和显示。
世界电网
This is where you define the properties of the world grid.
这是您定义世界网格属性的地方。
遗产模式
With this option you can switch to the behavior of the world grid. This option is only available for reasons of compatibility. If enabled, an automatic world grid will be used in all views and guidelines will be displayed and hidden automatically when a view is zoomed in/out.
使用这个选项，您可以切换到世界网格的行为。此选项仅出于兼容性原因可用。如果启用，将在所有视图中使用自动世界网格，并且当放大/缩小视图时，指南将自动显示和隐藏。
网格间距[0. . + ∞ m ]
Grid Spacing is the distance between grid lines.
网格间距是网格线之间的距离。
行[0. . 2147483647]
Lines enables you to choose the total number of grid lines (stretching over the X axis and Z axis); the default value is 100. When you choose a higher value, the grid will extend further towards the horizon. This setting is only relevant in the perspective views.
第行使您可以选择网格线的总数(沿 x 轴和 z 轴伸展) ; 默认值为100。当你选择一个更高的值时，网格将向地平线延伸更远。此设置仅与透视图相关。
Major Lines Every nth[1..2147483647]
每 n 行[1. . 2147483647]
The grid contains major interval lines that stand out from the others by their darker color. With this option you can choose how often these interval lines should occur.
网格包含主要的间隔线，这些线由于其较暗的颜色而显得与众不同。使用这个选项，您可以选择这些间隔行出现的频率。
动态网格
With this option you always get an optimal grid width on the screen, independently of the chosen grid spacing. This applies to the 2D viewports only. Use the drop-down list to choose the factors for the dynamic grid.
使用这个选项，您总是可以在屏幕上获得一个最佳的网格宽度，与所选择的网格间距无关。这仅适用于二维视窗。使用下拉列表为动态网格选择因子。
没有
If you select None, the grid is not dynamic and the grid spacing (with its default value of 100) remains constant, no matter how much you zoom.
如果选择 None，则网格不是动态的，而且网格间距(默认值为100)保持不变，无论缩放多少。
1.10
But if you select, say, 1 … 10, the grid is adjusted in steps of 10 as you zoom. If you zoom in and the spacing becomes too wide for the view, Cinema 4D switches automatically to a grid spacing of 10. If you zoom in nearer still, it is changed to 1. If you zoom out from the default grid and the grid width of 100 becomes too dense for clarity, it is first switched to a grid spacing of 1000 and then higher still as necessary should you zoom out further. There are no restrictions up or down.
但是如果你选择，比如说，1... 10，网格会在你放大的时候以10步的速度调整。如果你放大，间距变得太宽，视图，C4D 自动切换到10的网格间距。如果你放大得更近一些，它会变成1。如果你从默认网格缩小，网格宽度为100变得过于密集以至于不清晰，它首先被切换到1000的网格间距，然后如果你需要进一步缩小，它会更高。没有上下限制。

1. . 5. . 101. . 2. . 5. . 101. . 2. . 5. . 5. . 10
Selecting 1 … 5 … 10 means that grid widths of 1, 5, 10, 50, 100, 500, etc. can be achieved, whereas selecting 1 … 2 … 5 … 10 means that values such as 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, and so on, are possible.
选择1... 5... 10意味着可以实现1、5、10、50、100、500等的网格宽度，而选择1... 2... 5... 10意味着可以实现诸如0.1、0.2、0.5、1、2、5、10、20、50等值。
