How can I render back to front in opengl?

Question

I am trying to render an transparent object in opengl but sometimes the textures are visible through each other and sometimes they are not. As far as I know I have to render them from the back to the front and it is looking fine when I do it manually but only from a Specific perspective. Is there any method to calculate the order in which they should be rendererd?

If you have transparent objects, then you need to use Depth Peeling or some other Order-independent transparency method in order to properly render them if you aren't going to sort them.
