C O M P U T E R G R A P H I C S Guoying Zhao 13 / 16 Course studying Studying this course consists of three parts:  self-study with the book  following the lecture  doing the assignment work

C O M P U T E R G R A P H I C S Guoying Zhao 14 / 16 Homework The programming work has to be done with the OpenGL graphics library. Programs are to be written in the C++ programming language. –which ensures that you understand the concepts.  1. Basic C++ and OpenGL: keyboard, mouse;  2. Polygons (patches, polygons) and lighting  3. Drawings using OpenGL (or MFC): points, lines, circles; Polygon filling  4. Robot

C O M P U T E R G R A P H I C S Guoying Zhao 15 / 16 Grading Participants have to pass both written exam (50%) and practical programming assignments (50%) separately to finally get the credit points. Note: present to at least 10 lectures from total 14 lectures and 3 from in total 6 exercise and lab classes.
