View Full Version : multi-level layer rendering using Open GL?

Hi all,

Can any one help me, how to implement the multi-level (more then one layer) rendering.

If I start scaling the image, may be after 2-3 zoom-in operations, i should show one more image related to the previous.

ex: In a world map, if i show INDIA, then i will zoom the INDIA map. Now if i zoom further, i should be able to see states of INDIA, then in sub-sequent zoom, should be visible districts etc.

Please help me to get the logic or some examples.

thanks in advance,
