How to use Vector3.OrthoNormalize properly?

Greetings,

I`m currently trying to write a function to "orthogonalize" a Matrix. To accomplish that I thought I could extract the vectors of my matrix, use Vector3.OrthoNormalize(ref v0, ref v1, ref v2) and stuff them back into the matrix.

Note: I got that example from the Unity API: http://docs.unity3d.com/ScriptReference/Vector3.OrthoNormalize.html

But all it does is either nothing or set everything but [2,2] and [3,3] to 0. [2,2] and [3,3] will be set to 1 in that case(its pretty obvious for [3,3], since I´m personally setting it to that value). Sometimes even get some pretty random values like -0.345345.

Am I missing something? Is there even any sense in what I´m trying to accomplish?

Code (CSharp):

1. public Matrix4x4 matrixOrthogonal(Matrix4x4 matrix)
2.     {
3.         //Extract and orthogonalize vectors
4.         Vector3 v0 = matrix.GetColumn(0);
5.         Vector3 v1 = matrix.GetColumn(1);
6.         Vector3 v2 = matrix.GetColumn(2);
7.         Vector3.OrthoNormalize(ref v0, ref v1, ref v2);
8.  
9.         Matrix4x4 matrixOrtho = new Matrix4x4();
10.         matrixOrtho.SetColumn(0, v0);
11.         matrixOrtho.SetColumn(0, v1);
12.         matrixOrtho.SetColumn(0, v2);
13.         matrixOrtho[3, 3] = 1.0F;
14.  
15.         /*
16.         float stretchFactor = 1.0f;
17.         Matrix4x4 scale = new Matrix4x4();
18.         scale[0, 0] = stretchFactor;
19.         scale[1, 1] = 1.0F / stretchFactor;
20.         scale[2, 2] = 1.0F / stretchFactor;
21.         scale[3, 3] = 1.0F;
22.         Matrix4x4 fromNewSpace = toNewSpace.transpose;
23.         Matrix4x4 matrixOrtho = toNewSpace * scale * fromNewSpace;
24.         */
25.  
26.         Debug.Log("Matrix: " + "\n" + matrix);
27.         Debug.Log("Matrix orthogonal: " + "\n" + matrixOrtho);
28.  
29.         return matrixOrtho;
30.     }

 

Code (csharp):

1.  
2.         Matrix4x4 matrixOrtho = new Matrix4x4();
3.         matrixOrtho.SetColumn(0, v0);
4.         matrixOrtho.SetColumn(0, v1);
5.         matrixOrtho.SetColumn(0, v2);
6.         matrixOrtho[3, 3] = 1.0F;
7.  

shouldn't that be...

Code (csharp):

1.  
2.         Matrix4x4 matrixOrtho = new Matrix4x4();
3.         matrixOrtho.SetColumn(0, v0);
4.         matrixOrtho.SetColumn(1, v1);
5.         matrixOrtho.SetColumn(2, v2);
6.         matrixOrtho[3, 3] = 1.0F;
7.  

 

Yep thanks I just figured that out after hours of frustration, thanks though. Case closed.
