alpha blending

i am blending about 10/20 textured polygons but when i rotate the texture, i see the slices in the side view. i had written a similar application, but it didnt have this problem and i cant seem to find why this is happening. any suggestions??

This post does not contain information that lets us address what could be wrong.

You need to be more detailed about what you are doing, and what you expect to be happening. Posting screen shots of before/after somewhere and adding a link would be helpful.

Sounds like you’re not getting your matrices right, though; perhaps forgetting a MatrixMode somewhere – but that’s entirely conjecture, seeing as there’s no actual data to work from.
