Pre-requisites
: |
Formal
prerequisite for this course is Computer Graphics (either
undergraduate or graduate level). You should have familiarity
with basic calculus, linear algebra and geometry, and good
working knowledge of graphical programming (such as OpenGL,
DirectX, or Java3D).
|
|
Course
Description : |
This
class is intended to give students both a broader understanding
of geometric modeling and processing (through class discussions
and homework assignments) and in-depth experience with a particular
geometric modeling and processing topic (through a course project).
Among the specific topics to be covered are:
- Terminology,
coordinate systems, and implicit forms
- Basic
differential geometry of curves and surfaces
- Parametric
and spline representations of curves and surfaces and their
uses
- Subdivision
surfaces
- Solid
modeling paradigms and operations
- Geometric
mesh processing, including mesh simplification, reconstruction,
parameterization, editing, deformation, and morphing
- Advanced
or Application-oriented topics
|
|
Learning
Objectives : |
After
successful completion of this course, the students will be:
- Comfortable
with all of the major terms and concepts in geometric modeling
-
Able to apply concepts to specific geometric modeling problems
- Able
to implement key parts of certain modeling techniques
- Extremely
familiar with at least one topic of current interest related
to geometric modeling and processing
- Able
to independently read and study current geometric modeling
and processing research publications
- Prepared
to pursue further research in geometric modeling and processing

Grading
Policy : |
There
will be No Midterm Exams and No Final Exams! The final grade
will be based on programming assignments, project proposals,
demos, presentations, and reports. Each student is required
to complete two assignments and a final project. The programming
assignments and projects can be implemented in any of your
prefered programming environment (e.g. Windows, C++, OpenGL).
All the assignments and projects are mandatory. The final
grade will be composed of the following two parts:
- Programming
Assignments: 30%
- Assignment 1 (15%)
- Assignment 2 (15%)
-
Final Project: 70%
- Project proposal (10%)
- Midterm demo with preliminary results (10%)
- Final demo and presentation (10%)
- A working system and software codes (30%)
- Final Project Report (10%)
|
|
Project
Plan and Deadlines: |
- Study
a set of relevant papers (3-5 papers, throughout the semester).
- Submit
your own one-page course project proposal (deadline: TBA).
- Implement
basic functionalities and user interface before the mid-term
check point (deadline: TBA).
- Class
presenation and final project demonstration (at the end of
the semester, deadline: TBA).
- Final
report and source codes (at the end of the semester, deadline:
TBA).

Class
Attendance : |
I
expect the students to come to class, read and study the materials
and textbook. Download and print available materials from
WebCT prior to coming to class. The class schedule specifies
the chapters to read for each topic covered. Primary material
of this course will come from the required textbook. In addition,
material from recent articles or relevant reference books
will be presented. Numerous slides and video clips on graphics
will be shown. Students are advised to attend the class and
follow the lecture notes closely. It is the student¡¯s responsibility
to check what we covered in class and the announcements during
class if he or she did not attend.

Academic
Honesty : |
Copying
source code from another student in this class or obtaining
a solution from some other source will lead to an automatic
failure for this course and to a disciplinary action. Allowing
another student to copy one's work will be treated as an act
of academic dishonesty, leading to the same penalty as copying.
You should learn how to protect your data. Failure to do so
is also unprofessional and it may expose you to the danger
that someone will copy your homework and will submit it as
his or her own (see above). In this case, you may be given
a score of 0 for the assignment or project in question (and
the other party will get a failure).

- Important:
The dates in this schedule may change due to the class level.
If the class needs more time and examples to understand a
concept I will modify the schedule. If the class is ready
to skip a chapter or go faster I will modify the schedule.
Therefore, it is the student's responsibility to check what
we covered in class and the changes in the schedule announced
during class.
