i m new in android -ndk AR so need some help i m using Virtaul button sample (from Vuforia).
can i get the virtual touch to physical touch
like if i touch on the red botton on screen then tea pot changes to red
and if touch the blue button tea pot changes to blue tea pot ?
I figured it out at my own Need a complex caclution and Used the Following Formula to work with it
QCAR::CameraDevice& cameraDevice = QCAR::CameraDevice::getInstance();
const QCAR::CameraCalibration& cameraCalibration = cameraDevice.getCameraCalibration();
