Course Prerequisites: CPSC 441 or permission of instructor.

Textbook: There is no textbook. We will use recent research papers.

Topics and Goals: This course is designed to review recent papers in Geometric Modeling. Many of the papers we will cover have made a substantial impact in the world of Graphics and have applications to the game and movie industry. The goal of the course is to familiarize students with state-of-the-art techniques in Geometric Modeling with focus on mesh deformation, surface parameterization and surface reconstruction. By the end of the course, students should

• Be familiar with many of the recent papers in Geometric Modeling
• Have in depth knowledge of at least one of the papers we will be covering
• Be able to analyze current research papers in Geometric Modeling
• Be prepared to pursue further research in Geometric Modeling

Work Required: Given that the purpose of this class is to review much of the recent literature in Computer Graphics, we will be reading a number of papers. The class will consist mostly of presentations on the papers given by the students (some will be done by the instructor). Students will be expected to present two or more papers depending on enrollment, participate in class discussions as well as implement a course project based on one of the research papers we will be covering. Students will also be expected to turn in a short write-up of the paper being presented during each lecture summarizing and critiquing the paper.

Grading:

30%: Paper summaries

30%: Presentation

30%: Course project

10%: Class discussion

Below is a list of the papers that we will be covering. Not all of these papers may be covered depending on time, enrollment and student interest. I reserve the right to modify this list up to and including the start of the class based on enrollment and student interest.
