Toon/sketch rendering with nodes

Posted on by

edgeombre.jpgViralata has written two tutorials on his site using some of the new features of Blender 2.43 to achieve nice toon and sketch styled renderings. Are you tired of doing the same old photorealistic rendering? Try this out!

The tutorials guides you through this style of Non Photorealistic Rendering (known as NPR) step by step, ending up with good results that replicate hand drawn work quite well.

It’s certainly worth learning this and adding it to your toolbox of techniques. Being able to do some NPR is always a good thing.

      Wow, the result is pretty neat..
      Oh and btw, I didn’t even notice we got a new news writer (before now), good job Mathias!

      Doesn’t look too bad, thanks for the tutorial!

    • knittl

      gotta have to take a look

    • Crossmaker

      I did this a few days ago its great :)

      I am working on an entire scene with it.

    • criss

      Excellent tutorials!

      wow, this is pretty cool.

      Very nice!!!

    • Simon

      cool – thanks for this great tutorial

    • Jon

      A great, “one-to-read” tutorial!

      not bad…. but it would be great to have a render option using freestyle (http://freestyle.sourceforge.net/index.php) just as we have for Yafray.

    • Ronin

      Yep! I am tired of doing the same old photorealistic rendering.
      Viralata also has a very nice watercolor technique.

      I don’t know if it’s possible, but automating this a little more would be quite awesome. The steps are pretty immense. Call me lazy, but if I’m constantly doing this kind of render, I want to be able to make it a script.

      Kind of like how sketchup basically renders this way with one menu option. Minus the cross hatching of course.

      but I love that somebody took time, figured it all out, and then posted an instructional guide in two languages. Now THAT is community my friends.

    • OBI_Ron

      Thank you for the great tuts!

    • LIGHTspeed

      Looks really great!
      I’ve done somethings like it, but this way is a lot better.
      Thanks Viralata, and congrats on the splash screen win Mathias. :)

    • buergi

      wow result looks really cool quite very close to drawn cartoons, thx for the great tutorials

    • fritzman

      Cool tutorials! Thanx a lot.

      For those who haven’t yet, you gotta download and watch the simple animation “crayon” that Viralata did using a similar technique (link: http://matthieu3d.free.fr/animations/index.html – the bottom thumbnail) It’s look is just fantastic! I wonder how adding in a little bit of animation to the texture of the pencil strokes (like what COG teaches in his tutes – http://www.cogfilms.com) would look in such an animation… might have to give that a whirl… ;-)

      I think it might be a bit late to post this here, but I played around with this technique a bit after I read the news entry.

      The only thing that might be noteworthy in my attempt is that it doesn’t use any edge-rendering:

      Very nice, but did anyone successfuly managed to break the constraints of the vertices?
      It would be so cool to have a “sketch” like render using nodes..

    • http://mediawiki.blender.org/index.php/User:Hoehrer Höhrer

      @shul: What do you mean with “break the constraints of the vertices”?

      shul> It would be so cool to have a “sketch” like render using nodes..
      Tha (yusing nodes for the sketch rendering) is exactly what Viralata did in his tutorials .. dunno what else you could mean here, sorry.

      @Werner: when you create a sketch, you usually have artifacts from the sketching process which go beyond the boundaries of each object, here is an example: http://freestyle.sourceforge.net/GALLERY/SKETCHY/teapot-sketchy.php

    • http://mediawiki.blender.org/index.php/User:Hoehrer Höhrer

      @shul: I think this could be partially simulated by rendering out the border of each object (e.g with the Object ID pass), increase its size and blur it and “overlay” it with a sketch-like texture (hand drawn or procedural) similar to the process shown in the tutorial.

      I don’t know if I’m experienced enough to make this work (or rather “make it look good”) but if i find some time I’ll try it :)

      Forgot to mention: Of course the approach i mentioned above only has very random sketch-lines. These “tangent”-like guide-lines would be very hard to simulate right, especially since you would need to calculate the tangents direction somehow (script anybody?)
