70090 - Computer Graphics

Academic Year 2021/2022

Learning outcomes

At the end of the course, students know fundamentals of 3D computer graphics (polygonal modeling and real-time rendering). In particular, they are able to model and render scenes making use of suitable open source softwares and libraries.

Course contents

Raster-scan systems, I/O devices, graphics libraries, event-driven programming. 3D mesh and graphics representation. 2D/3D geometric transformations, viewing transformations, perspective and parallel projections, window-viewport transformations. Graphics pipeline. Real-time rendering, algorithms with hidden parts removal (hidden lines and hidden surfaces), illumination models and shading algorithms (Z-buffer), texture mapping. 3D polygonal models, curves and surfaces in parametric form, geometric modeling with spline and rational spline (NURBS) curves and surfaces, geometric modeling tools. The course provides a practical part where JavaScript programming language and WebGL/GLSL (C/C++ programming language and OpenGL/GLSL) graphics libraries will be used.

Teaching methods

Frontal lessons in class;

Practise;

Demo in class of software packages;

Seminars.

Assessment methods

The verification of learning takes place through the development of a project assigned in the last weeks of the course and which consists in the creation of an interactive-graphic 3D web application (for example a 3D video game).In carrying out this project, the student must use all the knowledge acquired during the course. The delivery of the project must be accompanied by a report (such as tutorials) in html language. The oral examination consists of exposing the project and in being able to discuss topics covered during the course.
