Outline edges

[puh]

I'm just want to ask if someone know or have any idea of how this could be done? Please compare two images of the same object (Right - what all we've got in our screens with Irrlicht, Left - what almost all modern 3D modelers can show):

Maybe there could be some kind of shader?

Any help and even thought will be helpful. Thank you in advanced.

yup Puh, you're looking for a cartoon cell shader. And it's possible, like u said, thru shaders. The problem is, how to write it?

Engines like OGRE or Kjapi already got it implemented. Perhaps checking how they're achieving it could be a start point.

maybe nvidias CG? or you try to fake cartoon shading if you apply it directly to the model

Actually I guessed it, but not sure.
All images I saw with cartoon cellshading was more ANIME-stylish.
OK, thank you both for such quick response, I'll try to find more info in google.

What you are looking to do is to show both the solid mesh and a modification of the wireframe. How you do this I don't know but it is possible to show the solid mesh with the wireframe, you will have to look at how to show and hide certain lines between verticies.

Hm, don't think so, as in this case outline couldn't be so clear. It will collide with solid and probably will disappear in some places. There is some kind of postrender with black lines.

Looks pretty much like cellshading to me...

add a flag to say "draw edge lines too" its very easy in opengl and dx

Robomaniac: in this case all triangles will be outlines? Sorry, I need a whole face outline, not every triangle.
