What is Computer Graphics?
•
•
The term computer graphics describes
any use of computers to create and
manipulate images [Marschner, S., et
al., 2015].
Computer graphics is the science and
art of communicating visually via a
computer’s display and its interaction
devices [Hughes, J. F., et al., 2013].
What is Computer Graphics?
•
Computer graphics is a cross-disciplinary field:
–
–
–
Physics (e.g.: model light behavior);
Mathematics (e.g.: describe shapes);
Human Perception (e.g.: only render things that will be
noticed);
–
–
Human-Computer Interaction (e.g.: interaction devices);
Engineering (e.g.: optimize allocation of memory, and
processor time);
–
Graphic Design and Art (e.g.: make the computer-to-
human communication more effective);
