Hi , I have been able to augment button on a marker image . I want to perform some action on button click. I have implemented tap gesture on the camera screen. I am fetching the 2d touch coordinates from the screen and converting them to 3d coordinates with this vuforia Api.
void projectScreenPointToPlane(Vuforia::Vec2F point, Vuforia::Vec3F planeCenter, Vuforia::Vec3F planeNormal,
Vuforia::Vec3F &intersection, Vuforia::Vec3F &lineStart, Vuforia::Vec3F &lineEnd);
But the 2d coordinates never matches with 3d coordinates of Augmented Buttons. I have attached the reference image on this link
Could someone help me on how to detect touch on the augmented button.
