Course Scope

Quote from Polygon Mesh Processing: "Geometry processing, or mesh processing, is a fast-growing area of research that uses concepts from applied mathematics, computer science, and engineering to design efficient algorithms for the acquisition, reconstruction, analysis, manipulation, simulation, and transmission of complex 3D models. Applications of geometry processing algorithms already cover a wide range of areas from multimedia, entertainment, and classical computer-aided design, to biomedical computing, reverse engineering, and scientific computing."


  • Working knowledge of C/C++

Classroom Behavior

During the lecture/resentation/demo, the students should not play games, text on your phone and surf the web. All electronic communication devices (including laptops, PDAs, cell phones) should be either turned off or silenced.


All required assignments should be completed by the stated due date and time. The total score of your finaly project score will be 10 points less every extra day after the due date (i.e., the 100 total points will become zero after 10 days pass the due date). You will be given 0 point for missing your own presentation.

Please note that plagiarizing will be penalized by maximum negative credit and cheating on the exam will earn you an F in the course. See the GMU Honor Code System and Policies at this page and this page. You are bound by these honor codes. Any submitted work which shows too much commonality with others' work to be completely original, or any plagiarized work, will receive a grade of 0. Any code which is presented in class or provided to you as part of the project may be included in your programs.

Accommodations for Disabilities

If you have a learning or physical difference that may affect your academic work, you will need to furnish appropriate documentation to GMU Disability Resource Center. If you qualify for accommodation, the DRC staff will give you a form detailing appropriate accommodations for your instructor. If you have such a condition, you must talk to the instructor during the first week of the term about the issue.
