透视对象

The Pivot Object was especially designed for use with the Motion System to interactively move, scale and rotate an animation within a Motion Clip interactively in the Viewport. To use the Pivot Object it must first be assigned to a Motion Clip. To do so, make sure you are in Motion Mode and activate a Motion Clip in the Timeline. Drag the Pivot Object into the "Pivot" field in the Attribute Manager’s Advanced tab. From this point on you can use the Pivot Object to modify this Clip’s position, scale and rotation. The Pivot Object can be used if, for example, you want to use several different Clips for a single object or hierarchy consecutively without causing a jump in the animation.

枢轴对象是专门为运动系统设计的，可以在 Viewport 交互式地移动、缩放和旋转动画片段。若要使用枢轴对象，必须首先将其分配给运动剪辑。要做到这一点，请确保您是在运动模式和激活动作剪辑的时间轴。拖动 Pivot 对象到属性管理器的高级选项卡中的“ Pivot”字段。从这一点上，您可以使用枢轴对象来修改此剪辑的位置，规模和旋转。例如，如果您希望为单个对象或层次结构连续使用多个不同的剪辑，而不会导致动画跳转，那么可以使用 Pivot 对象。

Let’s say you have two animations for a single character saved in separate Motion Clips, the first a walk cycle and the second a transition from walking to standing still. You want to use the walk cycle first and let it loop multiple times with the "Loop Relative" option enabled. After the walk cycle you want to apply the second Clip. Of course you will want to create a decent looking transition between these two animations. Naturally the second Clip should start where the first Clip ends, and the load-bearing foot in both animations should be at the same location during the transition. This is exactly what the Pivot Object is for.

让我们假设一个角色有两个动画保存在不同的运动剪辑中，第一个是步行循环，第二个是从步行到静止的过渡。您希望首先使用漫步循环，并在启用“ Loop Relative”选项的情况下让它循环多次。在步行循环之后，您要应用第二个剪辑。当然，你会希望在这两个动画之间创建一个体面的过渡。自然，第二个剪辑应该从第一个剪辑结束的地方开始，并且两个动画中的承载脚应该在过渡期间的同一位置。这正是枢轴对象的作用。

If the green check mark next to the Pivot Object in the Object Manager is deactivated, the Pivot Objects coordinates in relation to the Motion Clip can be modified. This way the position of the Pivot Object can be modified (or animated!) even after it has been assigned to a Clip. Once the Pivot Object is re-activated its new position will serve as the Motion Clip’s pivot point.

如果停用对象管理器中枢轴对象旁边的绿色复选标记，则可以修改枢轴对象相对于运动剪辑的坐标。这样枢轴对象的位置可以被修改(或者动画!)即使它已经被分配到一个剪辑。一旦枢轴对象被重新激活，它的新位置将作为运动剪辑的枢轴点。

An Example of How a Clip is Positioned.

剪辑如何定位的示例。

It is actually very easy to position a second Clip exactly where you want it. This is done as follows:

实际上，将第二个剪辑放置在你想要的位置是非常容易的:

• Let’s say the second Clip begins with the left foot being the load-bearing foot. We therefore have to select a point in the first animation at which the character’s left foot is the load-bearing foot, and this will be where the transition takes place. 让我们假设第二个剪辑以左脚为承重脚开始。因此，我们必须在第一个动画中选择一个点，在这一点上，角色的左脚是承重脚，这将是过渡发生的地方
• If you haven’t already done so, both Clips must be placed on the same layer in the Timeline while in Motion Mode (this can be done by Shift+dragging a layer). Position the second Clip so that it lies clearly behind the first (temporally) and drag the Timeslider to the beginning of the second Clip. 如果你还没有这样做，两个剪辑必须放置在同一层的时间轴，而在运动模式(这可以通过移位 + 拖动一个层)。定位第二个剪辑，以便它清楚地位于后面的第一个(暂时)和拖动时间利用程序到第二个剪辑的开始
• Switch to the Move Tool and open the Snap settings (press 切换到移动工具并打开管理单元设置(按P in the Viewport) and enable 在 Viewport 中) ，并启用Axis Snap 轴的卡扣.
• Now move the Pivot Object so that it matches the position of the left foot’s base Joint Object. Activate the Pivot Object. 现在移动枢轴物体，使其与左脚的基础关节物体的位置相匹配。激活枢轴对象
• Drag the Timeslider to the location in the first Clip at which the character’s left foot is the load-bearing foot. Position the Pivot Object until it matches the position of the same Joint (whose location is defined by the first Clip). Don’t forget to disable snapping when you are done. Otherwise it can lead to unwanted effects. 拖动分时器到第一个剪辑中角色的左脚为承重脚的位置。定位枢轴对象，直到它与同一关节的位置相匹配(其位置由第一个剪辑定义)。当你完成后，不要忘记关闭抓拍功能。否则会导致不必要的影响
• In the Timeline, position the second Clip within the first Clip so that the beginning of the second Clip lies exactly at the previously ascertained location. Test the animation. The transition can subsequently be adjusted and refined using the transition settings. 在时间轴中，将第二个剪辑放置在第一个剪辑中，使第二个剪辑的开头恰好位于先前确定的位置。测试动画。随后可以使用过渡设置来调整和细化过渡
