I'm using to display 3d model once the tracker image has detected and i have done the drag, rotate for the model appearing on the tracker but how can i apply zoom for 3d model with fingers and i've tried the zoom script from unity3D. It didn't work. Please help me on this
If the zoom script is trying to adjust the ARCamera's FOV or other parameters or trying to move the trackables, then it won't work since Vuforia retains control of the camera's transform and the trackable position is in relation to the ARCamera.
