Hi varun1.mehta, I believe monke99 was just referring to walking away from the target, phone in his hand, not to other type of zooming (check beginning of post).

Hey Monke99, Have you implemented zoom in/out functionality for Multitarget Sample for Vuforia iOS? Please revert back with answer if you have implemented.

Hi firstlook

You might want to try this function:

    virtual void setARProjection(float nearPlane, float farPlane) = 0;

which is in Renderer.h and is part of the renderer class.

I searched the web , but coudn't find the way to extend the distance of your far clip plane.

Which Vuforia SDK are you using?

Does it appear that the augmentation is sinking into the target? If so, try extending the distance of your far clip plane. Also there is a maximum distance for tracking, after which the apparent details of the image are insufficent to be detected any longer.

How small is the target when it disappears?

Can you post a screen shot with and without?

Hi monke99

When you say you "zoom out", do you mean within the application? or by moving the phone further away?
