OBJECTIVES

To provide the students with a theoretical and practical knowledge of computer graphics techniques, including the following:

1. Learn the basic rendering pipeline and rasterization (line drawing, clipping, polygon filling etc.) algorithms.
2. Learn the basic two dimensional and three dimensional transformations and apply them as a modeling tool for constructing scenes.
3. Learn hierarchical modeling and apply it to model and animate articulated structures, such as humans and robots.
4. Learn basic rendering techniques and apply them to generate photorealistic images of three dimensional scenes.
5. Learn basic geometric modeling techniques for modeling curves, surfaces, and solids.
6. Learn three dimensional viewing and projection techniques and apply them to generate two dimensional images of three dimensional scenes.
7. Design and implement a simple drawing program to apply various concepts learned in the class.
8. Design and implement a hierarchical modeling program to model and animate articulated structures.
9. Design and implement a program to implement a simple geometric modeling and rendering tool to model geometric objects and display them in wireframe, shaded and textured forms.

GRADING: (Tentative)
Midterm (20 %), Final (20 %), Programming Assignments (55 %), Attendance (5 %)
There will be three programming assignments that must be done individually.

You must use Web GL or Shader-based OpenGL on PCs (with Visual C++). For other languages/platforms, you have to set up your own environment and make necessary arrangements for the demonstrations.
