# SCNBillboardConstraint A constraint that orients a node to always point toward the current camera. ``` class SCNBillboardConstraint ``` ## Overview An [`SCNBillboardConstraint`](/documentation/SceneKit/SCNBillboardConstraint) object automatically adjusts a node’s orientation so that its local z-axis always points toward the [`pointOfView`](/documentation/SceneKit/SCNSceneRenderer/pointOfView) node currently being used to render the scene. For example, you can use a billboard constraint to efficiently render parts of a scene using two-dimensional sprite images instead of three-dimensional geometry—by mapping sprites onto planes affected by a billboard constraint, the sprites maintain their orientation with respect to the viewer. To attach constraints to an [`SCNNode`](/documentation/SceneKit/SCNNode) object, use its [`constraints`](/documentation/SceneKit/SCNNode/constraints) property. ## Topics ### Creating a Billboard Constraint [`billboardConstraint`](/documentation/SceneKit/SCNBillboardConstraint/billboardConstraint) Creates a new billboard constraint. ### Working with a Constraint’s Degrees of Freedom [`freeAxes`](/documentation/SceneKit/SCNBillboardConstraint/freeAxes) An option that specifies which degrees of freedom the constraint affects. ### Constants [`SCNBillboardAxis`](/documentation/SceneKit/SCNBillboardAxis) Options for locking the orientation of nodes affected by a billboard constraint. --- Copyright © 2026 Apple Inc.
