    Applies the inverse transform to the specified coordinates and returns the result in storeResult. If the storeResult is null, a new Vec3d is created to hold the value. Either way, the current instance is unaffected, unless storeResult is its translation or scaling.
    It IS safe for in and storeResult to be the same object.
    
    Parameters:
    
    in - the coordinates to transform (not null, unaffected unless it's storeResult)
    
    storeResult - storage for the result (modified if not null)
    
    Returns:

```
public Vec3d transformVector(Vec3d in,
                             Vec3d storeResult)
```
    Transforms the specified coordinates and returns the result in storeResult. If the storeResult is null, a new Vec3d is created to hold the value. Either way, the current instance is unaffected, unless storeResult is its scaling component or its translation component.
    It IS safe for in and storeResult to be the same object.
    
    Parameters:
    
    in - the coordinates to transform (not null, unaffected unless it's storeResult)
    
    storeResult - storage for the result (modified if not null)
    
    Returns:
    
    the transformed coordinates (either storeResult or a new Vec3d)
  - equals
```
public boolean equals(java.lang.Object otherObject)
```
    Tests for exact equality with the argument, distinguishing -0 from 0. If otherObject is null, false is returned. Either way, the current instance is unaffected.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    otherObject - the object to compare (may be null, unaffected)
    
    Returns:
    
    true if this and otherObject have identical values, otherwise false
  - hashCode
```
public int hashCode()
```
    Returns a hash code. If two transforms have identical values, they will have the same hash code. The current instance is unaffected.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    a 32-bit value for use in hashing
  - toString
```
public java.lang.String toString()
```
    Returns a string representation of the transform, which is unaffected. For example, the identity transform is represented by:
```
 TransformDp[ 0.0, 0.0, 0.0]
 [ 0.0, 0.0, 0.0, 1.0]
 [ 1.0 , 1.0, 1.0]
 
```
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
