```
    Compute linear (non-spherical) interpolations of this and the given quaternion q iteratively and store the result in dest.
    This method performs a series of small-step nlerp interpolations to avoid doing a costly spherical linear interpolation, like slerp, by subdividing the rotation arc between this and q via non-spherical linear interpolations as long as the absolute dot product of this and q is greater than the given dotThreshold parameter.

    It is defined as: D = T^-1 * Q, where T^-1 denotes the inverse of T.
    
    Parameters:
    
    other - the other quaternion
    
    dest - will hold the result
    
    Returns:
    
    dest
  - positiveX
```
Vector3f positiveX(Vector3f dir)
```
    Obtain the direction of +X before the rotation transformation represented by this quaternion is applied.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).invert();
 inv.transform(dir.set(1, 0, 0));
 
```
    Parameters:
    
    dir - will hold the direction of +X
    
    Returns:
    
    dir
  - normalizedPositiveX
```
Vector3f normalizedPositiveX(Vector3f dir)
```
    Obtain the direction of +X before the rotation transformation represented by this normalized quaternion is applied. The quaternion must be normalized for this method to work.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).conjugate();
 inv.transform(dir.set(1, 0, 0));
 
```
    Parameters:
    
    dir - will hold the direction of +X
    
    Returns:
    
    dir
  - positiveY
```
Vector3f positiveY(Vector3f dir)
```
    Obtain the direction of +Y before the rotation transformation represented by this quaternion is applied.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).invert();
 inv.transform(dir.set(0, 1, 0));
 
```
    Parameters:
    
    dir - will hold the direction of +Y
    
    Returns:
    
    dir
  - normalizedPositiveY
```
Vector3f normalizedPositiveY(Vector3f dir)
```
    Obtain the direction of +Y before the rotation transformation represented by this normalized quaternion is applied. The quaternion must be normalized for this method to work.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).conjugate();
 inv.transform(dir.set(0, 1, 0));
 
```
    Parameters:
    
    dir - will hold the direction of +Y
    
    Returns:
    
    dir
  - positiveZ
```
Vector3f positiveZ(Vector3f dir)
```
    Obtain the direction of +Z before the rotation transformation represented by this quaternion is applied.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).invert();
 inv.transform(dir.set(0, 0, 1));
 
```
    Parameters:
    
    dir - will hold the direction of +Z
    
    Returns:
    
    dir

Vector3f normalizedPositiveZ(Vector3f dir)
```
    Obtain the direction of +Z before the rotation transformation represented by this normalized quaternion is applied. The quaternion must be normalized for this method to work.
    This method is equivalent to the following code:
```
 Quaternionf inv = new Quaternionf(this).conjugate();
 inv.transform(dir.set(0, 0, 1));
 
```
    Parameters:
    
    dir - will hold the direction of +Z
    
    Returns:
    
    dir
