• Read the introduction and overview chapters of textbooks and reference books to get familiar with graphics basics and fundamentals. Research the introduction and overview chapters of OpenGL programming guide and reference manual in order to get familiar with the basics of OpenGL programming skills (2 weeks)
• Lab1: The main goal of Lab1 is to learn several important two dimensional graphics techniques and apply them such as line drawing, scan-conversion and two-dimensional transformations to solve real-world problems in practice. Students are required to implement the drawing of a polygon boundaries as well as its interior and be able to handle standard two-dimensional transformations and manipulations (3 weeks)
• Lab2: Lab focuses on applying three dimensional graphics techniques to display and manipulate geometric shapes in common use such as cube, tetrahedron, sphere, cylinder, cone, torus, etc. Students are required to implement the drawing of polyhedral objects and quadrics primitives. Students need to display wire frame objects, display flat-shaded solid objects, and allow users to interactively translate and zoom the displayed objects (3 weeks)
• Lab3: Lab3 aims at real-world applications by using graphics techniques. Typically, students are required to work on projects such as flight simulation, physics-based animation, collision detection of multi-objects and their physics-based responses, 2D or 3D shape morphing, etc. (3 weeks)
