Authors
Fabio Ganovelli is a researcher at the Visual Computing Laboratory, which is part of ISTI (Istituto Scienza e Tecnologie dell'Informazione),
an Institution of the Italian National Research Council (CNR). He graduated from University of Pisa in 1995, earned his PhD in 2001.
His research interest includes deformable objects, multi-resolution techniques, photorealistic rendering and geometry processing.
Massimiliano Corsini obtained his degree in Information Engineering from University of Florence in 2000.
In 2005, he obtained a PhD in Information and Telecommunication Engineering from the same University.
Currently, he is part of the permanent research staff of the Visual Computing Laboratory (ISTI-CNR, Pisa)
where he is working on appearance acquisition and modeling, 2D/3D registration techniques and image-based relighting.
Sumanta Pattanaik is an associate professor of Computer Science in the School of Electrical Engineering and Computer Science
at University of Central Florida, Orlando. Previously, he was a Research Associate at the Cornell Program of Computer Graphics,
Cornell University (1995-2001), a Post-Doctoral Associate at the SIAMES group of IRISA/INRIA, Rennes, France (1993-1995),

He received his PhD from the Department of Computer Science and Information Science of BITS, Pilani in November 1993.
The hobby of Marco Di Benedetto is Computer Graphics. Incidentally, it is also his research job (he is temporary researcher at Visual Computing Laboratory, ISTI-CNR).
Passionate software developer, his main objective is to realize rendering engine for real-time visualization of complex scenes,
both on powerful workstations and on off-the-shells smartphones.

Read carefully the accompanying instructions for a fruitful use of it.
A list of the clients
with a brief description follows. For each client, the part of the book where it is first explained is provided for reference.
Client 2/0 - The Very First Client
This is the very first working client. It does not do much, the car is a white triangle on an uniform background.
It is useful to learn how to do the initial setup.
This client is described in Section 4.8, page 120 of the book.
Live Demo
Drawing a cube
We learn here how to define a cube, representing it with a triangular mesh. This basic shape will be used later
to create our first 3D scene.
This client is described in Section XX, page XX of the book.
Live Demo
Drawing a cone
We learn here how to define a cone, representing it with a triangular mesh. This basic shape will be used later
to create our first 3D scene.
This client is described in Section XX, page XX of the book.
Live Demo
Drawing a cylinder
We learn here how to define a cylinder, representing it with a triangular mesh. This basic shape will be used later
to create our first 3D scene.
This client is described in Section XX, page XX of the book.
Live Demo
Client 4/0 - Our First 3D Client
We define our first 3D scene using the drawing primitive previously defined.
Note that, the 3D effect is limited since we are looking at the race with an orthogonal projection from above.
This client is described in Chapter 4, Section 10.1, page 128 of the book.
Live Demo
Client 4/1 - The Chaser View
In this client, the view frame is expressed as a function of the car's frame to follow the car during its movements.
This client is described in Chapter 4, Section 11.2, page 131 of the book.
Live Demo
Client 4/2 - The Observer Camera
This type of camera allows you to go around without constraints. With the W-A-S-D keys
you can change the position of the camera and with the mouse you can either look around
(like in a First Person Shooter game).
This client is described in Chapter 4, Section 12, page 136 of the book.
Live Demo
Client 5/0 - View From Driver Perspective
The view from inside the car is added to the client.
The driver perspective employs stenciling to avoid to redraw the inside of the car.
The blending technique is used for the upper part of the windshield.
This client is described in Chapter 5, Section 3.4, page 159, of the book.
Live Demo
Client 6/0 - Add the Sun
In this client the car made with boxes and cylinders is gone, replaced with a
3D model of the car. We learn here how to add a simple type of lighting: directional light.
We use directional light to simulate illumination from the sun.
This client is described in Chapter 6, Section 7.2, page 193, of the book.
Live Demo
Client 6/1 - Add the Street Lamps
We learn here how to use another type of light: point light. We use this type
of illumination to simulate the lamps at the border of the street.
This client is described in Chapter 6, Section 7.4, page 199, of the book.
Live Demo
Client 6/2 - Car's headlights and light in the tunnel
We learn how to use other two types of light: spotlights and area lights. We use spotlights to model the car headlights,
the first non-static lights we have (see Section 6.7.5). Moreover, we add lights in the tunnel
simulating area light with multiple point lights (see Section 6.7.6).
This client is described in Chapter 6, Section 7.7, page 203, of the book.
Live Demo
Client 6/3 - Phong Illumination Model
In this client we provide an implementation of the Phong Illumination Model.
This client is described in Chapter 6, Section 9.3, page 211, of the book.
Live Demo
Client 7/0 - Add Textures to the Terrain, Street and Buildings
Here we start using texture. The shaders for the street, the buildings and the ground just map the texture and ignore the lighting.
This client is described in Chapter 7, Section 5, page 227, of the book.
Live Demo
Client 7/1 - Add the Rear Mirror
In this client the rear mirror is added. To do that, we introduce the frame buffers.
In a first pass we render the scene as seen from the rear mirror and store the result in a frame buffer.
In a second pass, the previous image is used as a texture and applied to the rear mirror.
This client is described in Chapter 7, Section 6, page 230, of the book.
Live Demo
Client 7/2 - Add the Asphalt
In this client object space normal mapping is used to simulate the asphalt of the road.
This client is described in Chapter 7, Section 8.3, page 245, of the book.
Live Demo
Client 7/3 - Add a Skybox for the Horizon
The skybox is a very straightforward use of cubemaps to produce a convincing environment.
This client is described in Chapter 7, Section 7.3, page 238, of the book.
Live Demo
Client 7/4 - Add Reflections to the Car
Reflections on the car are made with 6 rendering passes that produce a cubemap.
These reflections look correct if the reflected environment is far enough.
This client is described in Chapter 7, Section 7.4, page 240, of the book.
Live Demo
Client 8/0 - Add Shadows
Basic shadow mapping with the depth bias trick explained in Section 8.4.
This client is described in Chapter 8, Section 3, page 263, of the book.
Live Demo
Client 8/1 - Shadow Mapping (PCF)
A better shadow mapping effect by means of the Percentage Closer Filtering (PCF) technique.
This client is described in Chapter 8, Section 3, page 263, of the book.
Live Demo
Client 9/0 - Add Fixed Screen Gadgets
Fixed Screen gadgets are added by drawing them in the NDC space, so that they are not affected by anything else.
This client is described in Chapter 9, Section 2.3, page 280, of the book.
Live Demo
Client 9/1 - Adding Lens Flare Effects
Here we use texturing and blending to create lens flare effect. This effect is largely abused, in fact
modern real lens make it not so common.
This client is described in Chapter 9, Section 2.4, page 281 of the book.
Live Demo
Client 9/2 - Better Trees
In this client, we leave the trees made with cylinders and cones for billboards.
We adopt axis aligned billboard, in this way they are always oriented towards the viewer.
This client is described in Chapter 9, Section 2.5.1, page 286 of the book.
Live Demo
Client 9/3 - Even Better Trees
Here the billboard clouds are used to obtain better trees.
This client is described in Chapter 9, Section 2.8.1, page 286 of the book.
Live Demo
Client 10/0 - A Better Photographer with Depth of Field
The depth of field effect of real cameras is simulated by blurring the pixels depending on their distance from the viewer.
This client is described in Chapter 10, Section 1.2, page 300 of the book.
Live Demo
Client 10/1 - Toon Shading
A very simple toon shading visual effect made by combining color quantization and edge detection.
This client is described in Chapter 10, Section 1.4, page 308 of the book.
Live Demo
Client 10/2 - A Better Photographer with Panning
In this client we simulate panning with a two-pass rendering technique. In the first pass, the velocity of each pixel is put on a buffer
which will be used in the second pass to blur the image appropriately.
This client is described in Chapter 10, Section 1.5, page 311 of the book.
