72953 - Principles Of Computer Graphics M

Learning outcomes

Knowledge of basic and advanced techniques for geometry processing and computer graphics, with particular reference to modeling and realistic rendering of 3D scenes on the computer.

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 modeling. The course includes a practical activity in which the HTML5 programming language + JavaScript + WebGL graphics library and GLSL programming will be used (module 1 (6 CFU)).

In module 2 (2 CFU) we will see the Three.js cross-browser JavaScript library, an API used to create interactive and animated 3D Computer Graphics applications on the Web using WebGL. Geometric modeling of NURBS curves and surfaces with examples in Three.js.

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. In completing this project, students must use only the knowledge acquired during the course. The project must be submitted at least 7 (seven) days before the exam and must be accompanied by a tutorial-style report in HTML.The oral examination consists of exposing the project and in being able to discuss topics covered during the course.
