I think I understood (more or less) how the pose matrix is used to render a 3D model with OpenGL. But I need to write a code that returns the coordinates of an object to the java class, i.e.:
the object is a MultiTarget; i would like to return (x,y) of a point on the MultiTarget to the Android application, which draws a circle on the screen (in (x,y)).
How can I do this?
Have you got any reference on Pose Matrix?
