Topics
Physics Bodies
class SCNPhysicsThe physics simulation attributes attached to a scene graph node.
class SCNPhysicsAn abstraction of a physics body’s solid volume for tuning collision detection.
Collision and Contact Detection
protocol SCNPhysicsMethods you can implement to respond when a contact or collision occurs between two physics bodies in a scene.
class SCNPhysicsDetailed information about a contact between two physics bodies in a scene’s physics simulation.
Physics in a Scene
class SCNPhysicsThe global simulation of collisions, gravity, joints, and other physics effects in a scene.
class SCNPhysicsAn object that applies forces, such as gravitation, electromagnetism, and turbulence, to physics bodies within a certain area of effect.
class SCNPhysicsThe abstract superclass for joints, vehicle simulations, and other high-level behaviors that incorporate multiple physics bodies.
Joints
class SCNPhysicsA physics behavior that connects two bodies and allows them to pivot around each other on a single axis.
class SCNPhysicsA physics behavior that connects two bodies and allows them to slide against each other and rotate around their connecting points.
class SCNPhysicsA physics behavior that connects two physics bodies and allows them to pivot around each other in any direction.
Vehicle Simulation
class SCNPhysicsA physics behavior that modifies a physics body to behave like a car, motorcycle, or other wheeled vehicle.
class SCNPhysicsThe appearance and physical characteristics of an individual wheel associated with an physics vehicle behavior.
