方法	描述
`static quaternion.euler(x: float, y: float, z: float) → quatf`	从欧拉角创建四元数。
`static quaternion.angle_axis(angle: float, axis: Vector3) → quatf`	从轴角创建四元数。
`static quaternion.look_rotation(forward: Vector3, up: Vector3 = ...) → quatf`	创建朝向目标方向的旋转。
`static quaternion.dot(a: quatf, b: quatf) → float`	Return the dot product of two quaternions.
`static quaternion.angle(a: quatf, b: quatf) → float`	Return the angle in degrees between two rotations.
`static quaternion.slerp(a: quatf, b: quatf, t: float) → quatf`	球面插值。
`static quaternion.lerp(a: quatf, b: quatf, t: float) → quatf`	Linearly interpolate between two quaternions (normalized).
`static quaternion.inverse(q: quatf) → quatf`	求逆。
`static quaternion.rotate_towards(from_: quatf, to: quatf, max_degrees_delta: float) → quatf`	Rotate from towards to by at most max_degrees_delta degrees.
