Lab on Computer Graphics

Notes above, such as medical imaging and visualization systems. However, for an introductory text,
it will suffice to present the two main techniques that are mixed and matched for the desired
results in practice.
In the text that follows, we will begin by attempting to understand the concepts of pixels and
how computer represent colour, which is the format for what computer graphics algorithms
output. After that, we will consider how we represent the input data that programs in computer
graphics use, the 3D objects that get rendered. With these basics out of the way, we will then
delve into the techniques of photo-realistic and real-time rendering. Figure 1.3 shows the basic
components of computer graphics.

• Computer graphics generally means creation, storage and manipulation of models and
images

• Computer graphics deals with all aspects of creating images with a computer
1. Hardware
2. Software

3. Applications
We use images/pictures?
• “One picture is better than a thousand words”
• Vision is the most important sense of humans

• Humans communicate well with images
Image Processing

• Digital Image Processing
○ Any form of signal processing for which the input is an image, the output of image
processing can be either an image or a set of characteristics or parameters related to
the image.
The Study Computer Graphics

The Computer Graphics program has been designed in reaction to demand from local industry
for graduates with technical abilities in programming in general and graphics in particular.
Feedback from prospective students has also been taken into account to produce a professional
qualification that covers a diverse and interesting range of subject material.
