hi where can you get tutorials and code on cel shading for directx and OpenGL? Thanks

This was answered a week ago - do a search for exactly the same topic in the appropriate forums (DirectX & Graphics)...

1) MSDN tutorial by Philip Taylor
2) Game Developer tutorial by Jeff Lander
3) nVidia developer website
4) Loads of academic websites with NPR projects going on

Not to mention the featured article link right on the front page.

I swear half the people here have never heard of a search engine.

Of course I saw the article on the main page. But if you look at links at the end of the article you will find
they aren''t that good.

In what way are those links (Philip Taylor & Jeff Lander) not that good ?

Both contain everything you need to get cel shading up and running (if you understand your API and lighting mathematics, cel shading really is easy to do, theres not much to explain - if it seems complicated, you probably need to revise some of the basics of lighting/your API) - once you know the concept, you'll most likely have tons of ideas for improvements.

www.nvidia.com/developer contains executables, papers and source demonstrating the 1D texture, vertex shader L.N setup, E.N outlines, MipMap outline thickening etc

Do you mean that the articles are too basic ? if you're after alternative NPR methods and other shader styles, hit the numerous academic research pages out there, for example:
