I'm making an Augmented Reality app for android, at the moment my app make the camera calibration, recognize an specific marker, classify it by ID and draw a 3D line. Now I have to draw a more complex 3d object like persons, cars etc... I know that it's necessary to use OpenGL, but I do not know nothing about it and all examples that I found don't show how to implements OpenGL in OpenCV images.

From what I understand you can' t draw with openGL on an opencv Mat. You may draw in opengl and somehow put the openCV image as a background (and i don' t really know enough openGL to suggest how to do it) but the other way around seems not so plausible : a 3d canvas such openGL may embed a 2d canvas such as the openCv Mat datastructure but not the other way around.
