Re: [isugamedev-devel] Alpha blending

[Kevin M. <ke...@vr...>]

unfortunately this wont work when you have a complex scene (like walls 
dividing rooms).  then you wont know if your geom is in front or behind a 
wall for example...

really, you do have to do the sort.  but the sort is easy with 
std::sort...  need code?  I have some.
