# Module 06-02408 (2014)

## Graphics 2

## Level 3/H

Ales Leonardis | Semester 2 | 10 credits |

### Outline

3D constructive graphics (co-ordinate systems, object and scene design, graphics transformations in 3D - translations, scaling, rotation, viewing); Animation; 2D raster graphics (algorithms for efficient drawing of lines and curves); Images and colour (image representations, image arithmetics, image enhancement, colour models).

### Aims

The aims of this module are to:

- further develop the concepts and terminology of computer graphics
- develop understanding of key representations and techniques of computer graphics
- develop skills in applying computer graphics techniques to construction and viewing problems

### Learning Outcomes

On successful completion of this module, the student should be able to:

- design wire-frame representations of 3-dimensional objects
- define matrices for 3-dimensional transformations
- explain and design algorithms for the viewing and projection of 3-dimensional objects using transformation matrices
- apply the relevant concepts of linear algebra and geometry to the design of computer graphics algorithms (e.g. vector and matrix operations and trigonometry)
- explain and design basic raster conversion algorithms
- explain the colour models and image representations

### Restrictions

No specific modules are required as prerequisites. Students will be expected to know or to learn independently the basics of the following mathematical concepts and techniques: general algebra (basic transformation of equations); analytical geometry (equations for line, surface, circle, ellipse etc); vector representation and algebra (addition and multiplication, dot product, cross-product); matrix representation and algebra (addition and multiplication).

### Teaching methods

2 hrs/week of lectures. Practical classes will also be available.

Contact Hours: 23

### Assessment

Sessional: 1.5 hr examination (80%), Continuous Assessment (20%).

Supplementary (where allowed): As the sessional assessment
