고급 컴퓨터 그래픽스 (Advanced Computer Graphics) Chung-Ang University. CSE Dept. Bong-Soo Sohn

Course Overview Level : CSE graduate course No required text. We will use lecture notes and on-line materials This course requires high level C/C++ programming skills Format Instructor lectures on graphics basics and OpenGL programming. Student presentation and discussion on graphics programming & advanced topics Conducting individual projects and presentation Course Objective Broad understanding of basic computer graphics Apply computer graphics knowledge to real graphics programming Deep experience with recent advanced topics

Graphics vs Vision Computer Vision Computer Graphics Image Processing Understanding the “content” of an obtained image (usually by creating a “model” of the depicted scene) Computer Graphics Creating an image from a computer model Image Processing Processing an image into another form of an image or features 3D Model 2D Image Graphics Vision

Computer Graphics Introduction Imaging : representing 2D images Modeling : representing 3D objects Rendering : drawing 2D images from 3D models Animation : models/scenes deform & move Modeling Rendering Animation

Example Virtual Billiard, 카트라이더
