<DIV>Well the flipping as suggested by D_E works but, I can't change the camera position, I tried to change the camera position and viewUp but everything gets mixed up. Is there any sample code or something you can refer me too? And also what's the advantage of changing camera location instead of flipping image?</DIV>
<DIV> </DIV>
<DIV>Thanks alot</DIV>
