Hi
Sorry I didn't mention earlier. I am using Unity plugin of EasyAR. In EasyAR SDK version 1.0 inside Engine class there is a function to obtain pojection matrix.
static Matrix4x4 GetProjection(CameraCalibration calib, float nearPlane, float farPlane)
But its not inside EasyAR SDK version 2.0. How to get it in updated versions of EasyAR.
Regards
Alan
