Damped Track Constraint 阻尼跟踪约束

The Damped Track constraint constrains one local axis of the owner to always point towards Target. This constraint uses a pure Swing rotation, i.e. the shortest possible single axis rotation. In other 3D software you can find it with the name “Look at” constraint.

Although usually associated with bones, Damped Track can align objects to point to (and follow) other objects or bones. It is important to note that the constraint aligns the origin’s axes to point to the target’s origin point. This is illustrated in the following figure. In each case the objects are set as Damped Track to +X.

A: Object vertices aligned along axis origin. B: Object vertices aligned away from origin.

Target 目标

数据ID 用于选择约束目标，当它为空时约束将不起作用(标题栏名称背景为红色状态)。

一旦自身物体已应用于阻尼跟随约束，然后，你必须选择物体哪个轴是你想要指向目标物体的。你可以在 6 轴方向之间选择 (-X、 Y、 Z、 X，Y，Z)。负轴方向导致物体沿选定的轴方向背对目标物体。
