Introduction to graphics and interaction

What is computer graphics and how does it differ from image processing and computer vision? What are interactive systems? Aims:

◮ understand common operations in computer graphics and

the basic properties of light and colour.

◮ understand the principles of interactive systems and how

to develop and evaluate human-computer interaction.

The aim of COMP30019 Graphics and Interaction

The objective of this subject is to understand the computational approaches to graphics and to gain proficiency in algorithms frequently used for robotics, graphics and related user interface applications. At the end of this subject, you should be able to

◮ encode geometric and lighting models on a computer for

displaying realistic objects and animated scenes in real-time (for humans),

◮ apply efficient algorithms for graphics and robotics

applications (on computers), and

◮ choose appropriate models for the design and

implementation of dynamic and interactive computer graphics applications.

Graphics and interaction: theory and practice

Computer graphics: concerns numerical algorithms for transforming geometric models into pixelated images (the main theme of this subject).

◮ Applications include computer games, computer aided

design, simulation and visualisation and forms the basis of all graphical user interfaces.

Graphics and interaction: theory and practice

Computer vision: concerns the transformation of images into models (the reverse of computer graphics).

◮ Applications include face recognition and robotic

perception such as used for mobile robots or pilotless aeroplanes or medical imaging. Image processing: concerns the transforming images into other images (typically used as an adjunct to graphics or vision).

◮ Applications include smoothing, sharpening, segmenting

• r automatically texturing images, also commonly used in

photographic editing.

• ffice, and more than 40% larger than the movie disc

industry in Australia.

◮ Video game industry has shown growth with sales

increasing 47% to $1.96 billion over 2008

◮ In 2008, 88% of Australian households have a device for

playing computer games.

◮ The average age of computer and video game players in

Australia is 30 years old.

◮ Females make up 46% of the player population in 2008.

Another application example

◮ ear surgery ◮ brain surgery

Exercise: an image question?

Images can vary in the number of dimensions represented according to their sources and can be either multi-dimensional, two- or one-dimensional. E.G. In the ear and brain surgery examples images clearly included 2D (individual image frames) and 3D (image sequences or movies). Question: can you think of other examples of images concerning different dimensions of

◮ 3D images involved in these applications (other than

space-space-time)?

◮ 2D images (other than images as they appear projected)? ◮ An example of a 1D image (yes, there is one involved)? ◮ An example of a 0D image?

subject.

◮ A mid-semester test 10%. ◮ To pass the subject you must obtain at least 50% overall

and 30/60 in the mid-semester test and the end-of-semester written examination.

Adrian Pearce University of Melbourne COMP30019 Graphics and InteractionIntroduction Introduction Aims Syllabus About me Application examples Textbook Assessment Project work Tutorials and labs

Project work

The subject will use OpenGL, specifically the C (optionally C++) GLUT bindings (installed on machines in labs).

◮ Project work will be done in small groups of 2–3 or

individually (note that assessment criteria will be the same, regardless of whether you do work in groups or individually).

Adrian Pearce University of Melbourne COMP30019 Graphics and InteractionIntroduction Introduction Aims Syllabus About me Application examples Textbook Assessment Project work Tutorials and labs

Why OpenGL?

Graphics programming in OpenGL is widely supported by numerous programming languages, including C/C++ and Java.

◮ You will be involved in programming an application in

OpenGL.

◮ The principles you will be exposed to will be directly

applicable to almost any graphics package, including DirectX or any other (future) language.

Do I need to learn OpenGL?

◮ We will be teaching an introduction to OpenGL but we

won’t be examining knowledge of OpenGL commands explicitly.

◮ You are expected to learn what you need of the OpenGL

API package, in your own time (time allocated for project work in the subject already takes this into account).

◮ In your project work you will be expected to learn (with the

assistance of your colleagues) enough of the package to get the project work done.

Adrian Pearce University of Melbourne COMP30019 Graphics and InteractionIntroduction Introduction Aims Syllabus About me Application examples Textbook Assessment Project work Tutorials and labs

OpenGL and GLUT resources and installation

◮ Specifically, COMP30019 will utilise C (optionally C++)

GLUT bindings (see http://www.xmission.com/∼nate/glut.html)

◮ You can use Visual Studio, installed in the computer labs

for programming.

◮ For free you can alternatively use Visual C++ Express with

freeglut (Microsoft) or dev-c++.

◮ If you run Linux, you should be OK using gcc, or if you use

Mac OS 10 the dev kit includes GLUT.

◮ OpenGL tutorials and example source routines are freely

available from numerous web sites (some of these links are on the LMS page).
