Teaching home research publications cv teaching 2011 Introduction to Graphics In this section of the course we will be learning about the principles of 2D graphics and basic image manipulation.

The two filters detect slightly different types of edge. (Ours is better at horizontal and vertical lines). Course Material and Notes Lecture Notes There is no official book. However, I will supply notes as we go along. Java2D Most information on the programming side comes straight from the source. The Java2D API Technology. Other Resources As indicated above, there is no single textbook for this course since books in this area tend to treat 2D graphics as a pre-cursor to 3D or image processing and thus they all miss large pieces of background. If you are desperate to have large amounts of dead tree in your hands, I suggest reading or (if you are rich) buying the following book which will help you understand Java2D and some of the underlying algorithms: Java 2D Graphics by Jonathan B. Knudsen (O'Reilly) If you are going to take 3D Computer Graphics in the 3rd year, then you might as well buy the following straight away: Computer Graphics and Virtual Enviroments by Slater, Steed and Chrysanthou (Addision-Wesley) Other books on 2D graphics and Java include (in decreasing order of relevance): Computer Graphics in Java by Leen Ammeraal, Leendert Ammeraal Hard to find, but it gets good reviews. Computer Graphics with Java by Gleen Rowe, Palgrave Has some in-depth material on how to implement many classic 2D algorithms in Java. However the 2D section is short, and then he talks about Java3D which we don't use. Java 2D API Graphics by Vincent Hardy (Prentice Hall) Graphics Programming with Java (2nd Edition) by Roger T. Stevens Very introductory level about Java2D and does not talk about the underlying algorithms. The Computer Image by Watt and Policarpo An introduction to many areas of graphics, from image processing through, vision to 3D Graphics. Useful as a basic reference if you are interested generally in graphics. Lab Exercises and Coursework There will be one un-marked lab exercise and one marked coursework. The un-marked exercise is in preparation for the coursework, so you should attempt it and get feedback from the lab demonstrator Neill Campbell in the lab sessions. The marked coursework, comprises a small number of programming exercises. Overall, coursework is worth 5% of the mark for 2011. Lab Sessions are Fridays 14:00-16:00 in MPEB 1.21 Lab Exercise (weeks 2&3) Purpose: Familiarity with Java2D, a little image processing. Coursework (weeks 3&4&5) Purpose: Curves and Hierarchical Transformations. Submission Date: Monday, Friday February 10th 2012 at 11:55pm (Moodle). Past Papers and Example Questions 2011 evolved from the course 2B16. The graphics material is the same. Note that 2B16 used to be called 2B14, so all of the following resources labelled 2B14 and 2B16 are appropriate for you. Past papers: Summer 2000 Summer 2001 Summer 2002 Summer 2003 Summer 2004 Summer 2005 Summer 2006
