is there someone who is able to write an easy to understand dot3-bumpmapping tutorial ? or at least an step by step instruction how to set up bumpmapping?
i think many people would benefit from this, like most of us once learned a lot from nehe's and other introductory tutorials...

humus has a nice little app on his site featuring dot3-bumpmapping (which includes source!)

Look for Spectragon on the following page:

I've also been wanting a "Nehe" or Gametutorials.com style tutorial for Dot3 bumpmapping. I've been able to get it working pretty well in my demo's through trial and error, following the demo's at Ati and Nvidia, and looking at the source available from people on here like NitroGL, Humus, and Nutty (among others).

I agree, though, that there are probably many people who would benefit from a straight-up tutorial on the subject.

His Spectragon demo does not include source yet according to the site

yes, all could benefit from such a tutorial. this knowledge should be shared, so that hobby opengl developer, wich code only vew hours a week, could implement bump mapping too. even the simplest game would benefit from the higher fake-detaillevel. i think i could manage dot3-bumpmapping too, but i simply have not the time to download the different techpapers from nvidia and ati and for example the kilgard-paper and work them through. what really get's me hooked is the tangent space stuff.
another strange problem: the radeon simple dot3-demo does not work on my radeon ve (radeon7000 core) card, while the much more complexer demo with dynamic lighting and cubemap normalisation does work.

@yakuza: could you probably at least make a collection of links to techpapers or demos such that on can start diving into the topic? this would be much help too!

kshots: you're correct. sorry about that.

nice general intro to ATI based bumpmapping if you haven't seen it already:

I've created a website containing a collection of links, papers and resources to the topic dot3bumpmapping. please post here additional links, of you know such.

I have a nice little normal map generator in my terrain engine. If anyone is interested in this, I could create a simple app. This will help for the bump mapping stuff.
I am also working on this dot3bumping. So, I will hopefully have it available shortly.
