Yes. I created an article about this topic for the next release of the Gamestudio Magazine (actually I created 3 articles for the next realease: bumpmapping, terrainshading and one article about creating normalmaps from high poly models). But unfortunately they are written in German. If there are enough people interested in that topic then I will translate one or more articles to English.

May be someone will help? I already asked that question in the Morbius but there were not many people to support an english version of our magazine.
