我工作的一个小Unity3D项目，我需要从另一个工具中导入一些数据。该工具使我的面向对象通过两个向量，我需要端口统一。

作为一个例子，我有这两个向量;

  X =向量（0.707，0.707，0）
Y =向量（-0.707，0.707，0）
 

由于只有这一信息，我需要了解我的对象需要在Z轴上旋转45度。这两个向量重新present我的对象，而不是起点，也不是终点的向上和向右载体。

修改

好了，现在我可以做单轴旋转！是啊！提供了这个功能;

 函数RotationMaster（VX：Vector3类型，VY：Vector3类型）{
    VAR VZ = Vector3.Cross（VX，VY）;

    VAR X = Mathf.Atan2（-vz.y，vz.z）* Mathf.Rad2Deg;
    变种Y = Mathf.Atan2（vx.z，其中Vx.x）* Mathf.Rad2Deg;
    变种Z = Mathf.Atan2（-vx.y，其中Vx.x）* Mathf.Rad2Deg;

    的debug.log（X：+ X +; Y：+ Y +; Z：+ Z）;

    transform.rotation = Quaternion.Euler（X，Y，Z）;
}
 

现在我可以通过简单的旋转这样的：

  RotationMaster（Vector3类型（1,0,0），Vector3类型（0,0.707,0.707））;
RotationMaster（Vector3类型（1,0,0），Vector3类型（0，-1,0））;
 

和，只要我不玩多轴，它会奏效。但只要我尝试更配合物旋转，失败......作为一个例子;

  RotationMaster（Vector3类型（-0.5，-0.5,0.707），Vector3类型（-0.707,0.707,0））;
 

这是错误的...： - （

任何线索？

  Quaternion.SetLookRotation
 

在（与一些调整...）我一直在寻找！感谢所有您的帮助！

I'm working on a small Unity3D project and I need to import some data from another tool. That tool gives me the object orientation through two vectors, and I need to port that to Unity.

As an example, I have these two vectors;

x = Vector( 0.707, 0.707, 0)
y = Vector(-0.707, 0.707, 0)

With only this information, I need to understand that my object needs to rotate 45 degrees on the Z axis. The two vectors represent the up and right vectors of my object, not a starting point nor a destination.

EDIT

Ok, now I'm able to do single-axis rotation! Yeah! Provided this function;

function RotationMaster (vx : Vector3, vy : Vector3) {
    var vz = Vector3.Cross(vx, vy);

    var x = Mathf.Atan2(-vz.y, vz.z) * Mathf.Rad2Deg;
    var y = Mathf.Atan2( vx.z, vx.x) * Mathf.Rad2Deg;
    var z = Mathf.Atan2(-vx.y, vx.x) * Mathf.Rad2Deg;

    Debug.Log("x : " + x + "; y : " + y + "; z : " + z);

    transform.rotation = Quaternion.Euler(x,y,z);
}

I can now pass simple rotation like that:

RotationMaster(Vector3(1,0,0), Vector3(0,0.707,0.707));
RotationMaster(Vector3(1,0,0), Vector3(0,-1,0));

And as long as I'm not playing with multiple axis, it will work. But as soon as I try a more complexe rotation, it fails... As an example;

RotationMaster(Vector3(-0.5,-0.5,0.707), Vector3(-0.707,0.707,0));

This is wrong... :-(

Any clue?

Quaternion.SetLookRotation

was (with few tweaks...) what I was looking for! Thanks to all for your help!
