What is CG? [1/2] • Computer graphics is concerned with all aspects of
producing pictures or images using a computer.
• The field began humbly almost 50 years ago, with the display of a few lines on a cathode-ray tube (CRT); now, we can create images by computer that are indistinguishable from photographs of real objects.
• We routinely train pilots with simulated airplanes, generating graphical displays of a virtual environment in real time.
• Feature-length movies made entirely by computer have been successful, both critically and financially.
What is CG? [2/2]
• The term ‘Computer Graphics’ – the representation and manipulation of pictorial data
by a computer
– the various technologies used to create and manipulate such pictorial data
– the images so produced, and the sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content
– Although the term often refers to three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing
What is ‘interactivity’? • HCI (Human–computer interaction)
– The study of interaction between people (users) and computers
– The intersection of computer science, behavioral sciences, design and several other fields of study
– Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware
Objectives
• To understand the fundamental topics in computer graphics – Graphics pipeline, shading models, texturing,
computer animation, rendering, etc.
• To learn how to design and implement 3D graphic software – Real-time HCI (human-computer interface)
• To have an impressive portfolio – The best way to get a nice job
Course Outline • 3 credits
– 2 lecture, 2 lab, 1 design
• Approach – More emphasis on practical programming
– Less emphasis on history and theory (math)
• Projects – Personal programming assignment (weekly lab)
– Team project (game or VFX competition)
• Textbook – Interactive Computer Graphics: A Top-Down Approach
Using OpenGL (5th ) by Edward Angel

No Hats
• Penalty in participation points
Cheating Policy
• Penalty will be very heavy
– 0 point in the related evaluation
– Deduct 10~20 points
OpenGL
• Open Graphics Library – API for 2D and 3D graphics programming
– Developed by Silicon Graphics
– OpenGL 3.0 was released on August 11, 2008
– Cross-platform (but MS has D3D)
– GLUT – The OpenGL Utility Toolkit
glColor3f(1.0, 0.0, 1.0); glBegin(GL_POLYGON); glVertex3f(0.1, 0.1, 0.0); glVertex3f(0.9, 0.1, 0.0); glVertex3f(0.1, 0.9, 0.0); glEnd();
