I did a quick search for topics on cell shading, found the nehe tutorial, and all. and think i have the basi idea. Know my question, how can different parts of my 3d obj, be different colors, and can there be a texture applied before the cell shading effect. Example would be, what if i wanted a Cell shaded soda can, that says "Buzz Cola" on it, like a little logo, but still want it cell shaded? am i makeing since? Oh and i am still new to this openGL world, so any info/links to examples of anything related would be great.

Not sure exactly where I saw it, but es, you can apply a texture, using multi texturing. From what I understand there are two ways to achieve cel shading. 1. use pixel shaders or 2. use multi-texturing, calculate your own lighting, and shade with a 1D texture.

I believe your textures will have to be cartoony too if thats the look your going for. Photo quality textures will appear photo quality, just with an unusual light gradient. I may be wrong, never tried it.

Yeah i was planning on keeping the textures cartoonish as well.

One last question, can there be alpha-blended cell-shaded objects on the screen?
