Find Trackable (x,y) Position on Screen ?

ok, maybe I should eloborate a bit... when a frame is rendered and a trackable is detected I can its position using: trackable->getPose()); which gets me an undocumented '3x4 QCAR pose matrix'. and can transform it to an (also undocumented)' QCAR::Matrix44F': QCAR::Matrix44F modelViewMatrix =

ok, so the position vector seems to be stored in [12] to [14], but x and y seem to be relative to z and z is not linear. Is there a util to normalize x and y ?

thank you for your answer ksiva. first, my knowledge in openGL is very limited, but I think the standart openGL transformations are not available in ES 2.0: "OpenGL ES 2.0 does not support the fixed function transformation and fragment pipeline of Op

sure, the code I posted above works just fine. xyPoint.data contains the coordinates. I think if you modify QCAR::Vec3F(0,0,0) you could somehow get the target's corners I could post some more code that tranfers the data to java if you want.
