just a quick study for semi-realistic "toon" rendering in Modo. The goal was to achieve a very graphic style for the objects, while also giving the impression they exist in the physical world. I'm planning to use this technique for rendering my CAD models...

one more quick test...

these look pretty cool!

the only thing that might get you into trouble with CAD models, is the way the edges look rounded, in some areas and flat in others.

Hi Rickei. thanks for your criticism, it's always good to know where i can make improvements. Especially with my track record of being wrong

... I made a little adjustment to lighten up that dark banding which you mentioned. It is a side effect of the gradient being used to fake the toon effect. But the same gradient band is also producing the "drawn" edge that defines the shape. So when i lightened the banding, it also lightened my edges. But overall i do feel it looks a bit better. Thanks!

rickei · 25th October 2007, 00:28

that does look better.

I don't have Modo yet, but I looks like I will in the near future.
so is this a rendering option in Modo or a "process" you came up with to fake a toon effect? I like it a lot

jbshorty · 25th October 2007, 01:14

There is no toon rendering option in Modo. So i'm faking it by projecting a color gradient onto the objects along the axis of the camera view. So the surface will change color depending on it's angle towards the camera. It's an old dog of a trick but it still works...

Could you post a scene file of this technique ? (something simple so I can have a look)

I have had modo for a couple of months but am still struggling with learning it. Although I hope to speed up when my Signature Courseware arrives.

Thanks.

Hi Are. Here is an example file and explanation :

At top of shader tree is the ground material group, which is a pure white color set to 100% diffuse value. It has blurry reflections set to only 10 rays if I remember correctly. This gives it the appearance of having a frosty finish without using a bump. This is the only material which is set differently than the "toon" objects. So I put it at the top of the stack to avoid complication.
Next thing down is the gradient which applies the fake toon effect to all groups below it. The mode is set to “multiply”.
Inside the groups for the torus and box, I am using a constant to set their color. Because there is no material in those groups, modo looks down the shader tree for the next available material. The material sitting alone at the bottom of the stack is being applied to the box and torus.
Environment is set to constant color of pure white.
Directional light is default settings. The only adjustment I made was the spread angle is now 3.8 degrees, and I turned up the samples to 70 so it would smooth out the shadow a little bit.
Global Illumination is turned on, all settings at default…

Thank you.

I've been playing with the beta of Brazil 2.0 rendering engine for Rhino 4. This seems to be a REALLY powerful engine. The toon shading is awesome, and the metal and glass shaders are really killer as well. I am getting much better results on metal and glass using Brazil for a few days than i am getting with Modo for almost one year

Anyway, here are the "toon render" test images of today...

These are really nice. Definitely prefer the Brazil ones!

Thought the Modo ones are still pretty good

Me too. Brazil uses a nodal shader system, so effects can be easily stacked. For example, i can make a wood table rendering with toon rendering outline and cel banding effects. Basically whole shaders can be placed inside any channel of any other shader. I've lots to learn about this engine, but so far i am very impressed with the results...

jbshorty · 8th January 2008, 00:39

thanks rickei. but all praise must surely go to Splutterfish for writing this engine...

vkirchner · 10th January 2008, 23:09

Nice looking Shorty, I have been using the Penguin product in the past. But this is an extremly nice output. I have not tried the Mental Ray toon shader in XSI yet. Too much struggling with the modeling part to worry about that yet, but I will be curious to see how it compares to what you have produced.

jbshorty · 10th January 2008, 23:36

Hi Vince. I've used the demo of Penguin 1 but never satisfied enough with the results to buy it. Penguin 2 has already been sent out for duplication, so that should be available very soon. And i know it will have much more advanced features. but not owning P1 i couldn't try the beta. Anyway i am extremely happy with toon rendering in Brazil. Here is a quick test i made yesterday of toon outline combined with photo-rendering...

jbshorty · 11th January 2008, 17:32

and here is my first "official" render in Brazil... my first time submitting for gallery entry. I wish i could submit more often, but i just rarely have time to do personal projects

Very nice

!

jbshorty · 12th January 2008, 00:09

Thanks Wim. Rendering is not my strongest skill. But I'm trying hard to improve on it lately. I still see things which i could have done better, but overall I think it's not too bad. Will make those improvements for my next works...

Nice rendering, shorty.

The most of my free time is taken in the practicing of the modeling (especially of modo) now.
I seem that my learning of rendering is still ahead.
