Lecture Slides

• Powerpoint
• Postscript

The contents of this lecture was derived from the "Interactive Walkthroughs of Large Geometric Datasets" course at SIGGRAPH 2000 (course 18). This course is offered yearly at SIGGRAPH, and updated to reflect new developments. There is also a course concentrating on level of detail only.

Lecture 5-2: Run-Time Level of Detail Control

Lecture Slides

• Powerpoint
• Postscript

This lecture was based on Jonathan Cohen's course notes for the SIGGRAPH 2000 "Interactive Walkthroughs of Large Geometric Datasets" course, and also on notes and papers discussed in the "Advanced Topics in Level of Detail" course.
