模式

Camera Track defines Direction

相机跟踪定义方向

An axis that uses the world coordinates will be placed through the start and end points of the solved camera animation. An axis that can be edited interactively in the Viewport will not be displayed. This mode is only designed for use with camera tracking.

使用世界坐标的轴将通过解决摄像机动画的起点和终点放置。可以在 Viewport 交互式编辑的轴将不会显示。这种模式只适用于摄像机跟踪。

Features define Direction

特征决定方向

This is the more commonly used option, which ascertains the wold or Object Tracker coordinate axes based on the vector aligned to the features.

这是更常用的选项，它根据与特性对齐的向量确定 wold 或 Object Tracker 坐标轴。

Axis

轴心

Use this setting to define the coordinates axis that the vector should represent. The vector will be displayed with the respective axis color in the Viewport.

使用此设置定义向量应该表示的坐标轴。矢量将显示与各自的轴颜色在 Viewport。

If None is selected, the axis will remain undefined.

如果没有选择，轴将保持未定义状态。

Reverse Axis

反向轴

Enable this option to reverse the axis, for example, if you have defined the Y axis and the camera or Object Tracker is upside-down.

启用此选项可以反转轴，例如，如果您已经定义了 y 轴，并且相机或对象跟踪器是倒置的。

Length

长度

The Length setting scales the vertex cluster to a realistic size. Estimate how long the vector would be in reality. In the above example you would match the vector for both (user) Tracks to the front edge of the keyboard. The keyboard is 43 cm wide, which is the value you would enter in the numeric field to the right of the Length setting, and the vertex cluster will be scaled accordingly so that both features associated with the Tracks will lie exactly 43 cm apart.

长度设置将顶点集群缩放到一个实际的大小。估计矢量在现实中的时间长度。在上面的例子中，您将匹配两个(用户)轨道的向量到键盘的前沿。键盘的宽度为43厘米，这是你在数字字段中长度设置右侧输入的值，顶点集群将相应缩放，这样两个与轨道相关的特征将正好相距43厘米。

Targets

目标

Target
Target

Drag the features into these fields that should serve as start and endpoints for the vector. Normally, these will be set automatically when the vector is positioned interactively in the Viewport.

将特性拖动到这些字段中，这些字段应该作为矢量的起始点和终结点。通常，当矢量交互式地定位在 Viewport 中时，将自动设置这些值。
