A point in the node’s parent’s coordinate system.
An offset that is added to the
zvalue after it is calculated.
A new constraint.
Each time when constraints are applied, a new angle is calculated so that a line projected at this angle would point at the target point. This angle is added to the values specified in the
radians property to create a new range. Finally, the node’s
z value is clamped to fit inside this range.
