Alt-B

用于自定义剪裁框以将3D视图显示限制为3D空间的一部分。可以帮助处理复杂的模型和场景。

Once activated, you have to draw a rectangle with the mouse. It becomes a clipping volume of four planes:

  • 如果是正交视图(译者注:额外四面垂直于裁剪时的视图所在平面),则为直角 平行六面体 (无限长)。

  • 如果是透视视图(译者注:额外四面交于裁剪时的视角位置),则是基于(译者注:底面)矩形的锥体(无限高度)。

Once clipping is used, you will only see what's inside the volume you defined. Tools such as paint, sculpt, selection, transform snapping, etc. will also ignore geometry outside the clipping bounds.

要删除裁剪,再次按 Alt-B

旋转视图后。

The Region/Volume clipping image shows an example of using the clipping tool with a cube. Start by activating the tool with Alt-B. This will generate a dashed cross-hair cursor. Click with the LMB and drag out a rectangular region. Now clipping is applied against that region in 3D space. Use the MMB to rotate the view and you will see that only what is inside the clipping volume is visible. All the editing tools still function as normal, but only within the clipping volume.

深灰色区域是剪裁空间本身。 一旦再次使用 Alt-B 将取消激活裁剪,所有3D空间将再次可见。

When using the Rendered shading mode, it can be quite slow to render the entire 3D Viewport. To fix this, you can define a subregion to render just a portion. This can be very useful for reducing render times for quick previews on an area of interest.

Apart from clearing the render region, you can also temporarily disable it in the Sidebar if you're not in Camera View, or in the Output tab of the Properties editor if you are.

Tip

If you set a render region while in camera view and have it enabled in the Output properties, it will be applied to the final render.
