Materials and Fixed Function Pipeline

Hi everybody,
I am sorry to come up with this topic again, but the more I read about COLLADA materials (constant, lambert, phong, blinn) and especially transparency handling I get more confused.

Could you please help me out and tell me how to convert the transparent and transparency elements of materials to OpenGL calls?

Take a look at the daeReader::processTransparencySettings method from this post to the OpenSceneGraph mailing list. It should make things more clear.
