as promissed here is a fullscreen 50 fps bump mapper done by fox in 98 which i have found on my old laptop lying for years... of course source code included... i am sure that fox does not mind to publish the source as bump mapping is nothing special anymore... ;)

ps. go and play "jade empire" which is a wonderful great game...

fast but uses different technique than real lambertian bump mapping. (like e.g. bump at end of numen demo) Anyway, kudos to fox!

i would say that its nearly the same bump mapper except that the texture is another one??? and there is no moving of the background?

I don't think so. Take a look at the light 'bulb' In fox's code you can see it , in eru's - you don't, you just see the bumped surface.
Maybe the mapper code is similar but it's surely not the same IMO.
