Description du produit
Présentation de l'éditeur
• Learn how to pinpoint problems with your lighting and solve them to produce professional results.
• Break scenes into passes and layers, and convincingly composite 3D models into real-world environments.
• Adopt a linear workflow for more convincing lighting, global illumination, and compositing.
• Apply advanced rendering techniques using subsurface scattering, physically based lighting, caustics, and high dynamic range images.
• Build a bigger bag of tricks by learning “old-school” approaches such as tweaking shadow maps, faking GI with occlusion passes, and other cheats and tricks that save render time.
• Develop realistic materials and shaders, and design and assign detailed texture maps to your models.
• Mimic photographic exposure and cinematography techniques to simulate real-life f-stops, lens breathing, bokeh effects, and Kelvin color temperatures for more photorealistic renderings.
• Learn to light characters and environments in different situations: day or night; natural or artificial lights; indoors or outdoors; and in clear air, thick atmosphere, or under water.
• Understand production pipelines at visual effects and animation studios, and prepare for collaborative work on large lighting teams
• Get the latest insights into industry trends, and how to develop your lighting reel and get a job in an increasingly competitive industry.
• Download many of the 3D scenes used in this book from the author’s website to try texturing, lighting, and compositing on your own

My interest is definitely in real-time rendering, so many of the topics were not directly relevant. However, I do have some experience with pre-rendered content creation, mostly noticeably during my time in art school, and some of the topics here were even beyond what I learned getting a 4 year degree. I will say that the material would be most apt for people doing film, and the book is certainly catering to that audience. However, in my case, I find a lot of the real-time books to be too narrowly focused on the algorithms and maths and not enough time is spent telling you how to use those methods to produce quality art. So I like looking at other sources to get a different perspective. Even in games there is some crossover, for example in cut-scenes or making promotional images, so the knowledge can still be useful. All-in-all I enjoyed the book and I would highly recommend it to any current or aspiring 3d artist.
It's updated with more information about popular technologies like ptex, and it reflects increased popularity and speed of global illumination in feature films.
He starts by explaining concepts of lighting, both technological and artistic. He continues going into specific methods and ways to use technology to achieve certain looks. Common errors are highlighted, good to know tricks are shown.
It manages to be generic and non-software specific where it needs to be, but still points you in the right direction when it comes to specific technology which may or may not be supported by your preferred software and other methods you may want to try to get a specific look.
The second edition has been recommended to me by VFX professionals, and it's with good reason. This is an improved version in every regard.
The Book is superbly presented in glossy paper format with excellently reproduced colour images that generously fill the book as examples of how to achieve the right lighting for that perfect shot you were trying to setup but till now had no idea of how to achieve it.
This volume is a how to for novice and advanced artist alike, brilliantly guiding you through the ins and outs of rendering the most perfectly realisticly shaded 3D image possible.
Chapters guide you through Lighting workflow, three point lighting, Shadows (a must),Qualities of light, Colour, Exposure, Composition and staging (worth the price of the book alone), Materials and rendering algorithms(tips to turn a good work into a masterpiece)and Compositing(the absolute icing on the cake).
There is a Lot one can learn from this volume and dare I say that it has to be if not the best then one of the very best presentations on this topic I've ever had the good fortune to study from.
The book gives a good look at the many aspects of the 3D rendering process without going too deep into technicalities : as such, it is a fitting read for beginners and intermediate users alike.
I'm re-reading the 3rd edition right now, I really liked the part related to the linear workflow (gamma correction), which to be honest had always puzzled me a bit in the past, but here it is explained with good clarity.
I definitely recommend this book, especially if you are just beginning your exploration into 3D. It will give you a first background of knowledge and put you on the right path.
