Non-Photorealistic Rendering (NPR) Paper Presentation Assignment
For this assignment, you will prepare and give an in-class presentation
of a paper related to non-photorealistic rendering (more properly called
artistic rendering, or something positive).
The papers to choose from are listed below. The papers selected
generally had high impact when they were originally published. Others
cover an important area of illustration or something very different from
the others. Some are just interesting or produce great pictures.
Some papers are paired, in which
case you should present both. The pairings generally couple a static
approach with its animated or real-time extension, and there is no need to
give each paper equal importance when presenting.
If, for some reason, you really wish to present a paper that isn't on
the list, ask me.
In the interests of simplicity, the first to claim a paper gets to
present it. Claim a paper by sending me email. I will use "sent time" to
judge "first". You can change your paper, but I'd rather you didn't.
When papers are claimed, they will be marked as such on this web page.
I have hard-copies of all of the papers (just one of each), most with
colour if relevant. I also have most of the pertinent SIGGRAPH proceedings,
and those that I don't have, Prof. Gleicher probably does have. Same
for videos. I strongly recommend tracking down the video if there is
one associated with your paper.

Preparing Your Presentation
The aim of your presentation is to give the flavour of the paper, not to
give all the details. Some key points to address (not exhaustive):
What style is the author trying to reproduce, or are they creating a
whole new style? Try to find representative images of the style as
rendered by an artist, and show them as part of your talk. Several of
the images in the papers are inspired by real paintings, which should
be easy to track down.
Is the approach for a single image, or for animations? If for single
images, what stands in the way of extending it to animation? If for
animation, how do they deal with the specific problems associated with
Does the approach work from photos/video, or 3d models, or is it
interactive? Does it make a difference?
What are the particularly good things about the approach, and what are its
poorer aspects? Are suggestions given for improvement? Remember, you
aren't really advocating the approach, so feel free to be critical.
Try to go into detail about one or two aspects of the paper, such as how they
solved a particular problem.
You should aim to talk for less than 30 minutes, and be prepared for
questions. A reasonable heuristic is that one slide lasts for two minutes,
but individuals vary slightly.
I will make every effort to help you print colour slides. It may be more
effective to pass a book around class for material that will not reproduce
well. Be sure to give me ample notice of any special requests (at least
This presentation will be worth approximately 20% of your final grade for
the course. I will be grading primarily on how well you convey the essence
of the paper, and how well you appear to grasp its content. Please view this
as very worthwhile practice for the future - a chance to talk in front of
a small friendly group with positive feedback.
Feel free to discuss your presentation with me before you give it, and to
discuss the papers with your fellow classmates.
