Hello,

     I'm now studying AR and have come to this problem:

     I want to locate multiple markers relative to a specific target, in order to know whether they are on the right position. But How can I calculate the distance between  markers ?  I thought raw information might be in the matrix got via getMarkerMatrix(), but I'm not sure how to handle the raw data in the matrix.

      would you please give me a hand?

      Thank you in advance.
