注意
To toggle the pivot point, you can press Z.要切换枢轴点,您可以按 Z

For example:例如:

  • If you select several nodes, set the pivot point toggle to Center, and rotate these nodes, they rotate around the center of selection as follows:如果选择多个节点,将枢轴点切换设置为 Center,然后旋转这些节点,它们将围绕选择中心旋转,如下所示:

    Pivot point in the center of selection选择中心的枢轴点
    注意
    If you scale the nodes, they are scaled out from or in toward the center of selection.如果您缩放节点,它们会从选择中心向外或向内缩放。
  • If you set the pivot point toggle to Pivot and rotate the selected nodes, each node will rotate around its center as follows:如果将枢轴点切换设置为 Pivot 并旋转选定节点,则每个节点将围绕其中心旋转,如下所示:

    Pivot point coincides with the center of the last selected node枢轴点与最后一个选定节点的中心重合
    注意
    If you scale nodes, each node is scaled relative to its center.如果缩放节点,则每个节点都相对于其中心进行缩放。

The basis of the manipulator pivot point can be toggled as follows:操纵器枢轴点的基础可以如下切换:

  • If the button is active, the world space orientation is used for the manipulator pivot point.如果 按钮处于活动状态,则世界空间方向将用于操纵器枢轴点。

    For example, if you set the combination for the selected nodes and rotate them around the Y axis, you will get the following:例如,如果您为选定的节点设置 组合并围绕 Y 轴旋转它们,您将得到以下信息:

    Before rotation: After rotation:
    Pivot point is oriented by the world space枢轴点以世界空间为导向
    Nodes have been rotated by 45 degrees around the Y axis节点已绕 Y 轴旋转 45 度
  • If the button is active, the coordinate system of the parent node is used for the pivot point orientation.如果 按钮处于活动状态,则父节点的坐标系用于枢轴点方向。

    For example, if you set the combination for the selected nodes and rotate them around the Y axis, you will get the following:例如,如果您为选定的节点设置 组合并围绕 Y 轴旋转它们,您将得到以下信息:

    Before rotation: After rotation:
    Pivot point is oriented by the local basis of the parent
    node (the red cube)
    枢轴点由父
    节点(红色立方体)的局部基础定向
    Nodes have been rotated by 45 degrees around the Y axis节点已绕 Y 轴旋转 45 度
  • If the button is active, the pivot point is oriented by the local coordinate system of the node. It means that its orientation does not depend on the parent node orientation.如果 按钮处于活动状态,则枢轴点由节点的局部坐标系定向。这意味着它的方向不依赖于父节点的方向。

    For example, if you set the combination for the selected nodes and rotate them around the Y axis, you will get the following:例如,如果您为选定的节点设置 组合并围绕 Y 轴旋转它们,您将得到以下信息:

    Before rotation: After rotation:
    The pivot point is oriented by the local basis of the last
    selected node (the green cube)
    枢轴点由最后
    选择的节点(绿色立方体)的局部基础定向
    The nodes have been rotated by 45 degrees around the Y axis节点已绕 Y 轴旋转 45 度
注意
To toggle the manipulator basis, you can press Z.要切换操纵器基础,您可以按 Z
