# AngularVelocityToQuaternion(float, float, TransformPlane)

> Calculate a Quaternion given a 2D angular velocity and a time to integrate over using the selected transform plane. If PhysicsWorld.TransformPlane.Custom is used, PhysicsWorld.TransformPlane.XY will be used instead which may not provide the correct results.
