                          float upZ)
```
    Apply a rotation transformation to this matrix to make -z point along dir.
    If M is this matrix and L the lookalong rotation matrix, then the new matrix will be M * L. So when transforming a vector v with the new matrix by using M * L * v, the lookalong rotation transformation will be applied first!
    In order to set the matrix to a lookalong transformation without post-multiplying it, use setLookAlong()
    
    Parameters:
    
    dirX - the x-coordinate of the direction to look along
    
    dirY - the y-coordinate of the direction to look along
    
    dirZ - the z-coordinate of the direction to look along
    
    upX - the x-coordinate of the up vector
    
    upY - the y-coordinate of the up vector
    
    upZ - the z-coordinate of the up vector
    
    Returns:
    
    this

    Set this matrix to its own normal matrix.
    Please note that, if this is an orthogonal matrix or a matrix whose columns are orthogonal vectors, then this method need not be invoked, since in that case this itself is its normal matrix. In this case, use set(Matrix3f) to set a given Matrix3f to this matrix.
