Two fingers touch to scale the Game object Vuforia

Am new to Vuforia, Is there any one who have done the similar approach of touching the game object and scaling it using two fingers?

Any help would be appreciated.

It is just like any other scaling, you collect the magnitude of the vector from touch 0 to touch 1 and you modify the scale the model that Vuforia is rendering. Only thing being that your object is probably a child so you change the localTransform.
