David's example is a good place to start.
When using alpha blending the key word is order. Your atoms must be ordered
from back to front in your models and your models ordered back to front in
your view. Also, not as obvious, the order the polygons that comprise your
atoms are draw matter sometimes too.
I posted a question regarding the latter a few weeks back and got a great

search deja.com for "+towler +pimento"
