Course Unit Page

Academic Year 2021/2022

Learning outcomes

At the end of the course, the student knows the basics of 3D computer graphics, with particular attention to both theoretical and computational mathematical aspects and is able to develop algorithms for 3D geometric modeling, real-time graphics and scientific visualization.

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.
