thanks.
i have tried it, it works well on my GF4 Ti4600,
but it is NV’s extension, does ATI cards support this extension
That’s correct. There is no pbuffer format with depth on ATi cards currently.
If you can use fragment programs, you can trick the card by putting the z in the rgb channels (this is how a depth texture would be looked up in a fragment program).
