Unity 根据所给方向计算Pitch、Yaw、Roll角的大小_pitch yaw roll坐标系如何计算偏转角

Pitch、Yaw、Roll角的概念

Pitch角，也叫俯仰角，用于描述物体绕x轴旋转的旋转角度。对应相机的上下旋转。

float pitch = Mathf.Atan2(direction.y, direction.z) * Mathf.Rad2Deg;

Yaw角，也叫航向角，用于描述物体绕y轴旋转的旋转角度。对应相机的水平旋转。

float yaw = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg;

Roll角，也叫横滚角，用于描述物体绕z轴旋转的旋转角度。相机应保持水平，不应该有横滚角。

代码

给定一个方向，让物体旋转到这个角度(其实用Quaternion.LookRotation就可以..

float GetYawAngleFromDirection(Vector3 direction)
{
    float yaw = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg;//所给方向与世界坐标系的z轴夹角(yaw angle，偏航角)
    return yaw;
}
 
float GetPitchAngleFromDirection(Vector3 direction)
{
    float pitch = Mathf.Atan2(direction.y, direction.z) * Mathf.Rad2Deg;
    return pitch;
}
 
float GetRollAngleFromDirection(Vector3 direction)
{
    float roll = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
    return roll;
}
 
public void LookRotation(Vector3 direction)
{
    transform.rotation = Quaternion.Euler(GetPitchAngleFromDirection(direction), GetYawAngleFromDirection(direction), GetRollAngleFromDirection(direction));
}
