comic book shading?

HIM · Post by **HIM** » Mon Dec 22, 2003 7:36 pm

I was toying around with the anim8or render program. And I managed to create a image that looked like a 3d comic book image. Basicly less detailed, "smeared shadows" and a contour around the objects.

So I was thinking if this could be made implemented with irrlicht. So if you are creative with the textures you should be able to get a decent look. But then there is the problem with reflection and ambience of the objects. Not to mention the contour.

Does anybody have a spontanious idea on how to fix this, or is it already implemented and I just can't find any info on the idea??

by comic book, do you just mean flat shaded? or do you mean you're using a cell-shading shader?

I can't quite remember what the shading style is called. But the use it in Jet Set Radio Future on the Xbox.

yes, that is called "Cell-Shading"

You mean like this...?

I hope to create a simple cel-shaded game in future. Probably a quick FPS frag-fest with XIII style graphics.

coool!!

have you figured out how to get irrlicht to create cellshaded graphics??

I've not really tried yet. I'm just working stuff out in my head. The trouble is whether or not Irrlicht draws back faces. If it does, then the models will all be solid black, if not, they will be cel-shaded... hopefully. If someone could tell me the answer then I'd be grateful.

(BTW, did you take your name from the band 'HIM'?)

im new to IRR, so I can only say 'i think' it is a setting. Not sure, but they've been pretty good about keeping things like that from both OGL and DX.

(or is 'HIM' a reference to PPGs)

Jep, its a setting. (bool irr::video::SMaterial::BackfaceCulling)

(that was me)
It's true by default.

I pointed this out in another thread. Most new games do cell shading with shaders which irrlicht doesn't do yet.

Using the fatboy/backfaces model, as above, you double the amount of polygons in your mesh.

True, but if you're trying to get a cartoony feel, then low poly models tend to look better, so you can get away with double polys.

The screenshots from milkshape don't represent a cel shading renedering style. They only show the outlining with a flat shading. Cel shading makes the light "solid": on a surface you can see only a limited number of ligt intesities as in this case
