Michael Cohen and John Wallace,Copies of the required books will be available in the textbook and general computer science sections of the campus bookstore. These books will be on reserve in the Math and CS Library.
Radiosity and Realistic Image Synthesis,
An Introduction to Ray Tracing,
(A basic text in computer graphics is recommended for background)
Foley, van Dam, Feiner, and Hughes,
Computer Graphics: Principles and Practice,
second edition in C, Addison-Wesley.
Texts used in current offerings of CS248
Additional material not covered in the texts will also be made available.
This consists of several research papers and possibly other materials providing
background for many of the lectures. Slides from the lectures will
also be made available via the CS 348b Home Page. The leftover hardcopies
of hadouts are available in the file cabinet in the copy room Gates 3B.
We will try to put most of material on the web.
1. Basic ray tracer - assigned Thursday April 8, due 11:59pm
Wednesday, April 21
2. Accelerated ray tracer - assigned Tuesday April 27, due 11:59pm Monday, May 10
3. Extending your ray tracer - assigned Tuesday May 18, demos all day Thursday, June 3, writeups due 11:59pm Monday, June 7
In addition to the programming assignments, there will be two written assignments designed to test your command of the more theoretical aspects of the course. These will be interleaved with the programming assignments as follows:
1. Sampling, antialiasing, texturing - assigned April 22,
due in class (*) April 29
2. Light transport and illumination - Assigned May 13, due in class (*) May 20
(*) SITN students may use the courier service
Collaboration: You may discuss the first two programming assignments with friends, but you are expected to implement your own solutions. On the third programming assignment, you are permitted (and encouraged) to form teams of two or three people and partition your planned extensions among the team members. Teams may discuss this assignment with other teams, but each team is expected to implement the extensions independently. In particular, code must not be shared between teams. The written assignments must be individual efforts.
Late assignments: Since each assignment builds on the previous one,
it is important that assignments be completed on time. To allow for unforeseeable
circumstances, you will be allowed one weekday of grace during the quarter.
Beyond this, late assignments will be penalized by 10% per weekday that
they are late. On programming assignment #3, neither the demo nor the writeup
may be late. Incompletes in this course are given only in exceptional circumstances.
All students with leland accounts automatically have accounts on these machines. Home directories on these machines are shared with other Stanford Computing Clusters using AFS. If you do not have a leland account, follow these instructions.
Software: To help focus your attention on the key ideas in each assignment, we will provide an interactive Inventor-based front-end program that allows you to assemble a scene from simple primitives, select viewing parameters, define directional or point light sources, and specify reflectance properties for each object in the scene. We will also provide an X support package that allows you to build a custom user interface for your ray tracer.
Using other platforms: Our front end-program and X support library will be installed on the Stanford Graphics Laboratory machines in Sweet Hall. We may also provide one or more 3D modeling programs. If you prefer working in your dorm room or workplace, and have access to a machine there, you are welcome to do the assignments on your own machines. We will make as many of these tools available via ftp as we are permitted by the terms of our licensing agreements, but we will not support them on any other platform. Moreover, your code must run on the SGI machines in Sweet Hall. In particular, we will grade your projects by running your programs on an SGI using our own test data files, and assignment #3 will be graded face-to-face in the Sweet Hall laboratory. It is your responsibility to copy and test your code on the Sweet Hall SGI's in time for grading.
Lab access: You will only need your Stanford ID card to get access to the SGI Lab at Sweet Hall (Room 029). SITN (TV) students should inquire directly from SITN re getting a temporary card.
