A constraint makes your ortho camera properly work with objects parented to it, so that they don’t move/scale when the user zooms the camera.
To influence some object, push a FixOrthoZoomConstraint instance into the Object3D.constraints array.
target — constraint's target object.
See the base TargetConstraint class for common properties.
Read-only flag to check if a given object is of type FixOrthoZoomConstraint.
The constraint's type. Equals to "FixOrthoZoomConstraint".
See the base TargetConstraint class for common methods.
