边界框是一个矩形框，在选中项周围尽可能紧密地包裹。方向与世界轴平行。 在此模式下，轴心点位于边界框的中心。可以使用 Comma 或通过编辑器标题栏中的菜单将轴心点设置为 边界框中心 。 下图显示了物体的边界框尺寸是如何由物体的尺寸决定的。

在物体模式

In Object Mode, transformation takes place relative to the location of the objects origin (indicated by the yellow circle), and the size of objects is not taken into account. The image below shows the results of using the Bounding Box as the pivot point in some situations.

单个物体旋转。

在此示例中，橙色矩形的原点位于网格的最左侧，而蓝色矩形的原点位于网格的中心。

选择单个物体时，旋转将围绕其原点进行。

The image above (left) shows that when multiple objects are selected, the pivot point is calculated based on the location of all the selected objects. More precisely, the centers of objects are taken into account.

在编辑模式

This time it is the geometry that is enclosed in the bounding box. The bounding box in Edit Mode takes no account of the object(s) origins, only the center of the selected vertices.
