In animation, a constraint that keeps an object’s orientation so that it aligns with the normal vectors of a NURBS or polygonal surface (mesh).

Normal constraints are useful for keeping an object oriented as it travels across a surface that has a unique, complex shape.

See also geometry constraint.
