Reading for Tues 9/2

Read the original Kajiya paper, The Rendering Equation, from SIGGRAPH 86. The parts relevant to the lecture are Sections 1-3.

Presentation Topics/Papers I

This is a first list of suggested papers, on the topic of ray tracing at interactive rates. I wanted to get this one on-line because it's a good topic to follow the current series of lectures. I'll post lists on more topics soon. If you're interested in this area but aren't sure what to choose, feel free to discuss it with me.

Subtopics are (1) hardware, (2) ray bundling and coherence, (3) animated scenes, and (4) acceleration data structures.

The 2006 course on Interactive Ray Tracing may be a good start in exploring this topic. Look on the public folder of my PC, \\lastra-cs, then navigate to SIGGRAPH and Courses. The course is missing the very latest work (post 2006), but much of that appears in the following venue.

There is a conference specializing in this topic, which began in 2006: The Symposium on Interactive Ray Tracing. Here are links to the papers. You can also get to them via the UNC library's link to the IEEE Digital Library.

Read for Th 8/28

Chapter 2 (by Pat Hanrahan) from the book by Cohen and Wallace, Radiosity and Realistic Image Synthesis, Academic Press, 1993. There is a copy of this chapter in the class notebook, located in the reading room. The notebook is red and is typically on top of the cabinet by the left set of windows.

Chapter 2 of Henrik Jensen's Photon Mapping book or Chapter 5 of Pharr & Humphreys are alternatives that cover the same material.

Read for Tues 8/26

A Realistic Camera Model for Computer Graphics, by Craig Kolb, Don Mitchell, and Pat Hanrahan, SIGGRAPH 95.

Readings for Th 8/21

Don Greenberg, et. al., “A Framework for Realistic Image Synthesis”, SIGGRAPH 97 special session.

[UPDATE: Read SIGGRAPH84 paper in preference to TOG]
Cook, Robert L., "Stochastic Sampling in Computer Graphics", TOG 1986. This is a follow-on to the previous paper: Cook, Porter, Carpenter, "Distributed Ray Tracing", SIGGRAPH 84.

I'd suggest you also read Turner Whitted's seminal paper, "An improved illumination model for shaded display", Communications of the ACM, June 1980.
