Cartoon rendering

A textured model wouldn't really be cartoonish, would it? ;)

I'm not sure it's really possible to do what you're imagining, but you could accomplish something close by combining texturing with a cartoon-shade pixel shader. Just use the texel color instead of the vertex color (YMMV)

I presume he's talking about cel-shading?

First thanks for your answer

I have tried the method explain at the end of the link above but it doesn't work well

I have certainly forget something :-(

If I test it on a very subdivised sphere it works (there is again some problems because the change of color take place where the vertex are so it is not very regular)

but on a lowpoly model it doesn't look like cel shading at all

here is the results I have :

The first cell-shaded game ever (Jet Grind Radio) already did it with textured objects: the character themselves have textured details. You need to use two texture units: have the character texture on channel #1, and the cartoon 1D ramp texture on channel #2, with some blending (modulate works fine), and have your shader change the UVs of channel #2.

My guess is that the main problem there is that your ramp texture is far too low in resolution. I'm not sure how to get around the subdivision issue, though.
