> Thank you for your response. I think z-buffer is applying some kind of smoothing to the data. Holes appear in a precipitation field in the x-window (which is the true representation of the data) while the images created with z-buffer the holes are filled in (maybe nearest pixel smoothing). I think it would be beneficial to see the images I am referring to. Is there a way to post images on here?

I seriously doubt there is smoothing going on in the Z-buffer. Are you
using the Z-buffer for actual buffering, or have you turned this off and
are just using the Z-buffer as another graphics window? Have you set the
size of the Z-buffer to match the size of your graphics window?

There is no way I know of to post images, here, but I doubt looking at
an image would be helpful anyway. It would probably be more helpful to
look at your code.

Cheers,

David
