CS 431/636 - Advanced Rendering Techniques
Description: The creation of realistic images from 3D models is central
to the development of computer graphics. The ray tracing algorithm has
become one of the most popular and powerful techniques for creating
photo-realistic images. Ray tracing's simplicity, elegance and ease of
implementation make it one of the most important image generation algorithms
in computer graphics. This class will explore in detail the algorithmic
components of ray tracing.
- Object representations
- Object-ray intersections
- Viewing/camera models
- Shading models
- Reflection & refraction models
- Acceleration techniques
- 2D/3D texture mapping
- Anti-aliasing & filtering
- Participating media
Students will implement many of these components in their class programming projects.
Other types of rendering algorithms will be discussed, e.g. radiosity,
volume rendering, non-photorealistic rendering and photon mapping.

I intend to use the standard grading scale of 100→ 90 (A), 89→ 80 (B),
79→ 70 (C), 69→ 60 (D), else (F).
Please also note that
incompletes will not be given for this course.
Graduate students will read a research paper and submit
a Powerpoint presentation that summarizes the paper. The deadline for
turning in the Powerpoint file is May 30th.
Choose a paper from this list.
It is a much shorter version of this list.
You may present another paper related to rendering, with the instructor's
The Powerpoint presentation should summarize the paper, contain
at least 10 slides, and include images and the paper's reference
Each assignment is worth 10 points.
Post several (at least 2) images generated from each assignment.
Make sure that your images and the objects in your images are big enough
to see/evaluate the effect implemented in each assignment.
Your images should leave no doubt that you have implemented a particular feature
Programming assignments may be written in any language, but must run
Collect and submit all of the needed files for an assignment in a single zip file.
Include a makefile and instructions in a README file on how to run your
program to create one of your example images.
You can use ImageMagick to read/write images.
Follow all of the instructions listed in the assignments.
5 points will be subtracted from an assignment if all of the
instructions aren't followed.
Assignments are due at 11:59PM on the due date. Well, ... I will honor the vampire rule.
Post images on the web and code on Bb Learn.
E-mail me the URL.
- One point off per day late, up to a maximum of 5 points.
- All regular assignments due last day of classes at 11:59 PM.
- No Incompletes!
It is expected that you will do you own work, i.e. write your own
software for the assignments.
You cannot "borrow" code from other
students or download programs from the Internet.
Specifically, you cannot use the code provided by the Suffern or
Shirley books (or their derivatives) for your assignments.
Any student violating this policy will be
given an 'F' for the class.
You may use image and basic math libraries,
e.g. for storing and manipulating vectors and matrices.
There will be a final exam on material not covered by the
Topics covered on the final exam are
Questions related to these topics will be in a short-answer format.
- Photon Mapping
- Volume Rendering
- Texture Mapping
- Spot Lights
- Sampling and Reconstruction
