Detect touch on OpenGL object?
<p>I am developing an application which uses OpenGL for rendering of the images.</p>

<p>Now I just want to determine the touch event on the opengl sphere object which I have drwn.</p>

<p>Here i draw 4 object on the screen. now how should I come to know that which object has been </p>

<p>touched. I have used onTouchEvent() method. But It gives me only x &amp; y co-ordinates but my </p>

<p>object is drawn in 3D.</p>

<p>please help since I am new to OpenGL.</p>

<p>Best Regards,
~Anup
