The teaching is organized as follows:

Learning objectives

This course aims at providing the student with the tools needed to master the algorithms and computational methods upon which many interactive computer graphics applications are based. The focus is on understanding the theory (geometry, radiometry) and the computational issues (algorithms, programming) that lie behind computer generated images. At the end of the course, the students will be able to: Understand the functionality of the graphics pipeline of modern computers; Understand the basics of 3D modeling and rendering algorithms; Design and implement simple interactive graphics/visualization applications; Describe effectively the technical feature of the applications developed; Use the acquired knowledge as a basis to pursue Visual Computing studies with independence.

Prerequisites and basic notions

Basic information on geometry and linear algebra

Program

1. Introduction
2. Draw with the computer: display, coding images and drawings, raster and vector images, rasterization, color and colorimetry

3. Geometric modeling: Euclidean space, 2D and 3D objects representation, curves, 3D models, constructive solid geometry (outline), spatial partitioning (outline), polygon meshes: encoding, characteristics, attributes, textures, processing algorithms, hierarchical models.

4. Rendering and lighting. Introduction to rendering: ray casting and rasterization, radiometry basics, BRDF, rendering equation, local and global lighting, materials, ray tracing, physically-based rendering, path tracing (outline)

5. Rasterization pipeline: geometric transformations, clipping, removal of hidden surfaces, scan conversion, interpolative shading, OpenGL pipeline, tricks, texture mapping, effects, and shadows

5 Animation. Keyframe animation, linear blending, skinning

6. Scientific visualization, principles, design, techniques for visualizing volumes

7. Laboratory (24h) Modeling of objects in Blender. Collections and hierarchies. Scripting. Animation. Materials, textures, and UV-mapping. Scientific visualization: ParaView.

Lectures and guided exercises in the laboratory

Learning assessment procedures

The verification of the profit takes place through a written test consisting of 4 open questions on the parts of the program and evaluation of the laboratory activities made through the delivery and correction of homework or with a replacement project.

Evaluation criteria

To pass the exam, the student must demonstrate -To have understood the basic concepts of creating synthetic images, Euclidean geometry, 3D object modeling and 3D rendering -To have understood the operation of the rasterization graphics pipeline -To know the principles and some techniques of scientific visualization - To be able to describe the aforementioned concepts in a clear and exhaustive way - To know how to apply the knowledge acquired by solving exercises or developing application projects

Criteria for the composition of the final grade

The grade will consist of 4/5 from the written evaluation and 1/5 from the evaluation of the homework or the replacement project
