cel-shading

I did a search and found many discussions on implementing real cel-shading using 1D textures. None of these discussions resulted in an implementation with source code available. I am using Irrlicht for a cel-shaded game. Therefore I need cel-shading implemented ASAP. In order to avoid duplication of effort I would like to make sure that no one else has already implemented this using 1D textures. If so, can you please share the source code? Note, I am not interested in pseudo cel-shading so thanks anyway

. If not, I'll be implementing it within the next few weeks. I'll post the source code here.

Why not just use Ogre which has supported it since last year?

Cause I'm sentimental, not rational.

Actually I prefer the less restrictive license.

a 1D texture is the same thing as a 2D texture where the height is always 1 pixel, isn't it?
So maybe it could work in Irrlicht...

Right... But when you display the model the texture coordinates depend on the results of the lighting equation, not on predefined texture coordinates. So even if I could load a 2D texture that is really 1D, I still need to change the way the models are rendered.

I'm not sure if this will work well with Irrlicht, but this is what I have done in Blitz to get cel-shading, anyways here goes...
---
After the model is loaded up and textured, I load another texture (1D) into the program and set it as a sphericle-map, from there I apply it to the model with the multiply texture flag set.

If I can get some free time away from my other projects I might try to re-make the effect inside of Irrlicht, if I'm able to do so I'll let you all know and post the source for it
