Relations > Basic Constraints >Direction constraint

Direction constraint


This relation forces one object to continually point at another. The follower rotates so that one of its axes (by default, its X axis) is always aligned with the position of the leader.

For example, you can add this constraint between a WebCam and an object so that the WebCam always points at the object.


To apply a direction constraint:
  1. Multi-select the follower (in this example the WebCam), and then the leader (the cone), in that order.
  2. Choose Relations > Direction Constraint.
  3. When you translate the leader, the follower continually rotates to point at the leader.

Direction Constraint Parameters

Active

Toggles the constraint on and off.

Weight

Determines the weight of this constraint in relation to other constraints acting on the object.

Constrained direction

Determines which of the follower's axes is aligned with the leader's center. By default it is the X axis. You can set the axis interactively by unlocking constraints and rotating the follower.
