- Munzner, Chapter 8.4.2 (Note: the textbook is available electronically through the UA Library for those on campus)
Real-Time Volume Graphics. Klaus Engel, Markus Hadwiger, Joe Kniss, Aaron Lefohn, Christof Rezk-Salama and Daniel Weiskopf. In ACM Siggraph 2004, Course 28, 2004.
While I recommend the book, you can Focus on Chapters 1, 3 and Sections III and VII in the coursenotes their SIGGRAPH 2004 course, as well as
the slides from newer coursenotes from EG 2006, specifically parts 1,3,5-7.
