Présentation de l'éditeur

In Detail

Blender provides a broad spectrum of modeling, texturing, lighting, animation and video post-processing functionality in one package. It provides cross-platform interoperability, extensibility and a tightly integrated workflow. Blender is one of the most popular Open Source 3D graphics applications in the world.

Modern GPUs (Graphics Processing Unit) have some limitations for rendering complex scenes. This is mainly because of limited memory, and interactivity issues when the same graphics card is also used for displaying and rendering frames. This is where Cycles rendering engine comes into play. Cycles is bundled as an add-on with Blender. Some of the features of Cycles is its quality, speed and having integrated industry standard libraries.


This book will show you how to carry out your first steps in Cycles - a brand new rendering engine for Blender. In a gradual and logical way, you will learn how to create complex shaders and lighting setups to face any kind of situation that you may find in Computer Graphics.

This book provides information on how to setup your first application in Cycles. You will start by adding lights, materials, and textures to your scene. When it’s time for the final render, you will see how to setup Cycles in the best way. You will learn about a wide variety of materials, lighting, techniques, tips, and tricks to get the best out of Cycles. Further on in the book, you will get to know about animation and still shots, and learn how to create advanced materials for realistic rendering, as well cartoon style shaders.

This cookbook contains a wide range of different scenes, proposed in a structured and progressive order. During this journey, you will get involved in the concepts behind every step you take in order to really master what you learn.

Approach

An in-depth guide full of step-by-step recipes to explore the concepts behind the usage of Cycles. Packed with illustrations, and lots of tips and tricks; the easy-to-understand nature of the book will help the reader understand even the most complex concepts with ease.

Who this book is for

If you are a digital artist who already knows your way around Blender, and you want to learn about the new Cycles’ rendering engine, this is the book for you. Even experts will be able to pick up new tips and tricks to make the most of the rendering capabilities of Cycles.

Biographie de l'auteur

Bernardo Iraci

Bernardo Iraci was born in Livorno, Italy in 1985. He followed a standard education career until he graduated in Economics in 2009. He always had a great passion for computers, especially gaming. During the latter part of his studies, he also developed a passion for 3D graphics, and this soon became the main focus of his career. It was at this time that he came to understand that his passion was the most important thing to pursue, more important than even attending university.

Even though Bernardo later participated in various online courses teaching the different aspects of computer graphics, he has been largely self-taught. In 2010, he moved to Warsaw, Poland, where he was finally able to start working full-time in computer graphics as a 3D generalist in the field of movies VFX and advertisments. He also started work as a freelancer.

Bernardo constantly works to improve his skills and knowledge about computer graphics and thinks that this is the only way to keep pace with this field. When he is not busy with graphics, he likes to travel, watch movies, and play the guitar.

HASH(0x924c5f60) étoiles sur 5 Images unreadably small -- good writing ruined. 13 janvier 2014
Par M. B. Stevens - Publié sur Amazon.com
Format: Broché Achat vérifié
Many of the all black and white images are so small that even with a magnifying glass the ben-day dots are so grainy you can't read what the depicted nodes are supposed to be. Of course, you download the support files and open them in Blender. OK, I understand that. But don't expect Packt's website to be a pleasant experience either.
$45 bucks is way too much to pay for something with unreadable images.
You have to be at the computer with a blend open to use most of the book.
The physical book is a disaster.

Like another reviewer, I feel badly for the author, Bernardo Iraci. All this is _not_ his fault -- he seems to know exactly what he's doing and his writing is quite clear to me. My two-star review would have been four or five stars if the physical book had been usable.

HASH(0x924c6540) étoiles sur 5 This book contain a lot of good information, but be prepared, you are going to have to work for it. 30 janvier 2014
Par dreamsgate - Publié sur Amazon.com
Format: Broché
I was recently contacted by Packt Publishing and asked to review Blender Cycles: Lighting and Rendering Cookbook by Bernardo Iraci.

So first up, what is this book about. From the title you would assume that it focuses on lighting and rendering, and while those topics are discussed in detail, the primary focus is actually on creation of materials that render well in specific lighting conditions. Which on further thought, actually makes sense. Materials, lighting and rendering need to all work together for a polished look.

Now that we know what main topics are being discussed, here is a quick look at the table of contents so you can see what type of lighting situations are covered.

Chapter 1: Key Holder and Wallet Studio Shot
Chapter 2: Creating Different Glass Materials in Cycles
Chapter 3: Creating an Interior Scene
Chapter 4: Creating an Exterior Scene
Chapter 5: Creating a Cartoonish Scene
Chapter 6: Creating a Toy Movie Scene
Chapter 7: Car Rendering in Cycles
Chapter 8: Creating a Car Animation
Chapter 9: Creating an Iceberg Scene
Chapter 10: Creating Food Materials in Cycles

Purchase of this book of course comes with downloadable project files. There are two blend files for each chapter, one project blend ready for you to use as you follow along and a finished result blend that has all the materials and lights set up. The project blend contains all the models needed to complete each "recipe". All the models are saved with any needed UV maps, Vertex Groups, etc. already set up. Leaving you to focus on the topic at hand.

The files are valuable resources both for the models and all the materials and lights. There is also a texture folder filled with all the needed texture images for each project as well as an "Additional Materials" blend that contains materials not covered in the recipes for you to use and study.

The layout of the book is Packts' familiar "cookbook" format. Each chapter has a short introduction, the "recipes" which give a step by step breakdown and then the "How it's Done" sections where further explanation is given.

So now we get to the part you all really want to know. How good is it?

Well, like most things in life, there are some good things and some not so good things about this book. Let's tackle the not so good first and get it over with.

The Not So Good

Over the years I have read a great many computer/software books. When it comes to the editing of these books I am fairly tolerant of editing mistakes, because I know how easy it is to miss the occasional mistake here and there. Grammar, minor spelling and editing errors don't get me wound up and more often than not, when reviewing these books I only mention such errors briefly if at all.

That being said, Blender Cycles: Lighting and Rendering Cookbook suffers from not just a few editing errors, but enough errors that it does make the book considerably more difficult to follow. There are awkward passages that don't make sense on first reading (or even several readings), spelling mistakes, missing steps in the recipes, with the biggest problem being the mismatched file names for models/objects and image textures throughout the entire book.

Using Cycles is not difficult, but it can get complicated rather quickly with nodes connecting in everywhere, so having to stop and figure out what files, objects or textures are supposed to be used at any given point as well as the missing step here and there, makes a complicated subject just that much more difficult.

The Good

After reading the "not so good", you are probably wondering what was good about this book, and there was still quite a bit of good to be found.

Bernardo is actually quite knowledgeable when it comes to how to set up materials, lighting and rendering in cycles. Something that is obvious from the finished materials themselves as well as in the "How it is Done" sections after each set of recipes. Between the individual materials, lighting set ups and rendering settings, there is an amazing amount of information to absorb.

The materials and lighting setups are not only useful as they are, but also as a jumping off point for your own experiments and exploration. I learned a great deal about what was possible in Cycles as well as how it all worked together. In fact there were a few recipes I have noted for future projects of mine that will be very useful.

One of the things I did enjoy most about the book was the variety of materials that were covered. These are not your simple "make it red and shiny" materials, these are useful and adaptable with built in controls for fine tuning the material to your needs.

So there it is, the good and the not so good. With one remaining question to be answered. Would I pick this book again knowing what I now know about it?

The answer is quite likely, and here is why.

1. I actually like a challenge, and while this book was difficult (okay some sections were more than difficult) and I wouldn't recommend it to beginners, it was not impossible and I think I may have ultimately understood more because I did have to work at it. Yes I know, I am seriously weird that way. :P

2. The book covers a lot of really nice materials with good explanations of why things work. I like knowing why. :)

One final thought

This book contain a lot of information, but be prepared, you are going to have to work for it.

HASH(0x924c6408) étoiles sur 5 You get what you came for, but it's a bumpy ride. 29 janvier 2014
Par irascibleone - Publié sur Amazon.com
Format: Broché
As I read through the book, I found there was plenty to like. I am quite pleased with how much I learned and will likely use this book for future reference. The results of each chapter were quite satisfying and the book is completely focused on the subject at hand. The starter files mean no wasted time modeling or doing off-topic tasks.

I also liked the recommended links included at the end of many sections. I find this very useful for a second voice on a related topic or having resources for future projects. Also, the deeper you get into the book, the more advanced projects get. While you do repeat things from previous chapters, I find it really helps solidify it in your memory.

While I am quite pleased with what I got out of the book, there were a handful of issues that concern me. Here's a quick list of what I ran into:

- Inconsistencies between the text, the images, and/or the completed Blend file.
- File names in the book sometimes don't match the names of the downloaded files.
- Odd wording and/or odd ordering of steps (I got used to this after a few chapters).
- Occasionally there are missing/implied/assumed steps that you have to figure out on your own.
- Every chapter uses a starter file, however, there are times where steps are already done.

None of these are insurmountable. The process may not have been a very smooth, but I was able to finish the book, get the intended results, and learn a lot along the way. But what bothers me the most is that everything wrong with this book should have been fixed during a proof read. It feels like a rough draft with all the concepts, ideas, and content present but not much polish after that.

In the end, I am torn on this book. On one hand, there's some really good content, good explanations at the end of each recipe, and a lot of great things to learn. On the other hand, the combination of the issues mentioned above are really holding this book back. If I were to sum it all up in one sentence, I'd say you get what you came for, but it's a bumpy ride along the way.
HASH(0x924c6894) étoiles sur 5 A Very Good Read 25 janvier 2014
Par Ann Rodela - Publié sur Amazon.com
Format: Broché
Reading this book I came to realize how Blender can produce images with photorealism accuracy. The author's recipes are float point precision from RGB colors, Index of Refraction to factoring levels in mixing nodes. Photographic terms: depth of field, bokeh effect and exposure levels are used. Bernardo begins by discussing GPU vs. CPU and video cards. He introduces the reader to the three point light system using emitting planes and gives those lighted mesh subtle hues. I like the way he lights the environment. An hdr image is loaded in the environment texture which adds reflection. He uses sun position along with an IBL plug in and chooses Latitude, Longitude and Time settings for the outdoor landscape. Grass is made with the particle system which is ready for animation. He guides the reader for changing the scenes. The interior scene with plant, lamp, chair bathed in sunlight becomes night. IES, a plug in used by professionals, saves on polygon count. Throughout the book the author maintains focus on the lighting, IOR, rendering time, nodes while he develops textures for a glass full of water, a glass of wine, bottle of wine, grapes, a car with realistic reflections, toys inside a space ship, and a model of a young lady by the sea.

After having worked my way through several of the first chapters of this book I have found it difficult at times to follow the instructions that are in it. I have been using Blender for many years now and the instructions though well intended fall short at times with miss direction, missing information, or just a plain over assumption of knowledge and terminology to accomplish a procedure. Either directions do not match illustrations, or information and files are missing to complete the steps needed to finish a project. Only with repeated efforts to complete single steps on single projects was I able to finish the projects that I attempted to create. The results were very good with this effort but the process would have been more rewarding had there been more precise, accurate information and illustrations to go along with the information given. I looked forward to learning new things using Blender 3D and enjoying the process along the way. Instead I found it to be a struggle just to get through the first couple of chapters because of the manner in which the information was presented. This is definitely not a book for a first time user to create anything using Blender. If you have no knowledge of Blender 3D basics this book will be of no use to you. Even if you have used Blender for a number of years as I have be prepared to start learning all over again….. slowly and not easily.
