The goal of the course is to make students understand how a graphic system works, both in terms of its software and hardware components. Moreover, students will learn how to analyze, design and evaluate graphics applications and their outputs. In particular, students will achieve knowledge outcomes related to the topics below: - The human visual system - Color perception and color models - Hardware of graphics systems - Graphics primitives and attributes - Graphics formats - 3D models geometry and manipulation - 3D rendering - Local and global illumination models - The quest for photorealism - Interaction techniques, design of graphic applications and interfaces - Main graphics tools, libraries, languages and standards Students will develop skills pertaining to: Creation and manipulation of 2D/3D graphics elements via polygonal modeling and their management using graphics libraries Configuration of light sources and of graphics attributes (color, transparency, etc.) for 2D/3D content Use of 2D/3D textures to control the appearance of graphics objects Configuration of a rendering engine to get the desired level of realism Management of the basic functionalities of a physics engine for simulating fluids, particle systems, etc.

Basics of computer science and programming languages. Basics of geometry.

Tentative programme of the 30 hours in class: - The human visual system, light perception and representation of colors (6 hours) - Hardware of graphics systems, graphics peripherals (3 hours) - 3D geometries, curves and surfaces (3 hours) - Solid and polygonal modeling (3 hours) - Transformations and projections (3 hours) - Local and global illumination models , photorealism (4,5 hours) - Primitives, graphics pipeline and rendering (4,5 hours) - Common graphics formats and software (3 hours)

In addition to the 30 hours of in-class lessons, the course includes 30 hours in the laboratory. The laboratory activities involve the use of software and libraries for modeling and rendering 3D static scenes and for implementing interactive applications. Laboratory activities, which are preparatory for the development of an individual or group project that contributes to the determination of the final grade, will focus on the following subjects: - Introduction to the use of modeling and rendering tool (3 hours) - Modeling techniques (6 hours) - Development of interactive graphics applications (6 hours) - Libraries for importing and managing 3D models and scenes (3 hours) - Lighting and materials for rendering 3D content (3 hours) - Texture mapping (3 hours) - Particle systems and fluid simulation, force fields and collisions (6 hours)

Reference books (to be selected based on software tools used): - Introduction to Computer Graphics, Foley, Van Dan, Feiner, Hughes, Phillips - Blender Foundations: The Essential Guide to Learning Blender 2.6, Hess - OpenGL Programming Guide: The Official Guide to Learning OpenGL, Shreiner - X3Dom Primer: Learn the basics of how to code 3D objects and scenes to display on the web, Bucaro - WebGL: Up and Running: Building 3D Graphics for the Web, Parisi Further specific references could be provided at the beginning and during the course. Additional material: - Slides (in-class lessons and laboratory sessions), exam topics and other material on the Portale della Didattica - Wikis, e.g., Blender 3D: Noob to Pro - https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro - Tutorials, e.g., at http://www.blender.org - Lesson screencasts

Exam: Written test; Individual project; Group project;

The exam consists of a written test and of a laboratory project, which contribute to the final grade in an equal way. Results of the two parts are expressed on a scale from 0 to 30, and the exam is considered as passed if the evaluation obtained by averaging the above results is at least 18/30. The written test, whose approximate duration is one hour, is aimed to assess students' knowledge of topics listed in the official program of the course and their ability to apply theoretical concepts in solving exercises (usually, the test includes one open-ended question/exercise for each topic in the program, scored from 1 to 3). The use of books, notes, solved exercises, formularies, calculators and similar material will not be allowed during the written test. The project, carried out in an individual or group way, proposed by students and agreed with the teacher, is aimed at creating a static 3D scene and an interactive graphics application by starting from the notions acquired during laboratory sessions. Evaluation of the project will consider which and how many modeling techniques and approaches for managing created geometries have been applied among those presented during the course, and with which results. Project has to be delivered (discussed) in one of the dates of the written test. During the discussion, students will be asked questions aimed to assess the individual contribution to the project. Up to 2 additional points can be assigned in the evaluation of both the written test (for the rigor) and the laboratory project (for the use of methods and tools not presented during the course and characterized by a significant complexity). These point allows the student to get the 30 cum laude grade. Results obtained in the two parts and final grade are published on the Portale della Didattica.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
