This is from the Autodesk Masterclass series for SigGraph 2009. Originally posted on the AREA website, for some reason it got cut off in the fourth video. This is a re-posting of the entire presentation with the exception of the very ending. I intentionally cut off the links from this video as they have changed.
These techniques are often called "cartoon" and while animation and cartoons are what got me into this career at an early age, I personally avoid using that term when describing these particular shading and rendering techniques to customers. This is largely because "the C-word" often has negative connotations of children, childish things etc. Please consider this non-photorealistic, stylized, technical illustration etc. **unless** you are specifically discussing cartoons with your clients. Trust me!
Since the time of this recording, there have also been more features added to 3ds Max for non-photorealistic rendering. Most notably are the Nitrous Stylized Viewport options available to the Quicksilver GPU rendering engine. Several of those workflows are featured on another of my previous blog posts from Autodesk University 2011 >>> HERE.
