I haven't changed this particular code in a couple of weeks, but it seems deleting a target recently stopped working, with HTTP 400:
GET /targets/4de2e4b9cf154d78bfe3baa6722ab952
{"result_code"=>"Success", "transaction_id"=>"fb1da348a8134c3ca5615e5807c652a0", "target_record"=>{"target_id"=>"4de2e4b9cf154d78bfe3baa6722ab952", "active_flag"=>true, "name"=>"REDACTED", "width"=>194.0, "tracking_rating"=>2, "reco_rating"=>""}, "status"=>"success"}
DELETE /targets/4de2e4b9cf154d78bfe3baa6722ab952
{"result_code"=>"Fail", "transaction_id"=>"bcd16bec92e644339ffe336044fe0053"}
The signature calculation code is identical between GET and DELETE
converting Matrix34F (trackable pose) to screen coordinates
The pose is simply a 3D transformation, it is not an object in its own right that has a "location".

Here are instructions for projecting points from target to screen space for both Android and iOS..

converting Matrix34F (trackable pose) to screen coordinates
Thanks for the replies. However I am new to OpenGL and did not fully understand the code snippet. Could you please share mechanism to draw a rectangle around the trackable target? Or drawing/moving the target in 3D to 2D screen?
