    private int mHeight;
    private float mPpx;
    private float mPpy;
    private float mFx;
    private float mFy;

  Hi Yixun Liu  A RealSense Java script at the link below demonstrates accessing intrinsics with the get_intrinsics instruction.

  It looks this API is different from the Java API shipped with RealSense SDK. It does provide the interface I need but lacks documentation and examples. Can I used it along with the Java API shipped with RealSense SDK or exclusively?

  RealSense support for Java took two separate forms: the official Android wrapper, and an unofficial non-Android Java wrapper that a RealSense community member developed.

  The link below discusses accessing intrinsics and extrinsics via the official Android wrapper.
