Purpose of Course:
This course covers the fundamentals of geometric modeling, including design of curves and surfaces, composite curves and surfaces, and subdivision techniques for creating free-form shapes.

Contents:

1. Mathematical preliminaries
2. Cubic Hermite curves
3. Bézier curves
4. B-spline curves
5. Properties of curves
6. Bicubic Hermite surfaces
7. Bézier surfaces
8. B-spline surfaces
9. Subdivision surfaces
10. Implicit surfaces
11. Intrinsic properties of curves and surfaces

Learning Goals:
Students will learn the basic mathematical tools to design geometric models and practice implementation of some of them.

Projects:
There will be three projects and two midterm exams. Each project will require about 15 hours of work, and each midterm will cover about a month of materials covered in class.

Grading Policy:
Programming assignments will worth 50% the midterms will worth 50% of the overall grade. Following grades are guaranteed A: 90..100, B: 80..89, C:70..79, D: 60..69, E: 0..59.

Calendar:

Midterms: On 10/6 and 11/3
