    The book Game Engine Black Book Doom was just released by Fabien Sanglard just in time for the 25th anniversary of the release of Doom.  The book, with forwards by John Carmack and Dave Taylor, is an in-depth look at the details and techniques that went in to creating the classic game Doom.  In addition to dissecting the code in the idTech game engine, the book looks at the hardware and software of the day as well as a details of porting to a variety of different consoles.

    Details from the author’s homepage:

    From November 2017 to November 2018, it took one year to complete. Both John Carmack and Dave Taylor kindly wrote forewords. The result is 427 pages, full color, to describe in great detail the PCs of the era (Intel 80486, VESA Local BUS, Dos Extenders, Watcom Compiler, ...), the NeXT hardware (and especially the NeXTStation TurboColor), the engine, and the console ports to the Jaguar, Sega 32X, Super Nintendo, Sony Playstation, 3DO, and Sega Saturn.


    I wish the paper version could have been priced lower. A black and white version would have been cheaper ($39.00) but given the many screenshots and drawings, readability would have suffered. I tried to look around but all printers gave me roughly the same price for a 400+ pages full color book. If anybody has an idea to lower the price I will listen carefully.


    The book is available in print form on Amazon, as well as on Google in DRM free e-book form.

    The academy award winning book Physically Based Rendering from Theory to Implementation 3rd Edition is now available free online in it’s entirety at http://www.pbr-book.org/.  This book is hugely important to the game and film industry as this is where the expression Physically Based Rendering (PBR) was coined, and it is the underlying rendering technology behind every major modern 3D game engine.

    Description of PBR 3rd Edition from the book homepage:

    Physically Based Rendering, Third Edition describes both the mathematical theory behind a modern photorealistic rendering system as well as its practical implementation. A method known as “literate programming” combines human-readable documentation and source code into a single reference that is specifically designed to aid comprehension. Through the ideas and software in this book, you will learn to design and employ a full-featured rendering system for creating stunning imagery.

    This new edition greatly refines its best-selling predecessor by adding sections on bidirectional light transport; stochastic progressive photon mapping; a significantly-improved subsurface scattering implementation; numerical robustness issues in ray-object intersection; microfacet reflection models; realistic camera models; and much more. These updates reflect the current state-of-the-art technology, and along with the lucid pairing of text and code, ensure the book's leading position as a reference text for those working in rendering.

    The author team of Matt Pharr, Greg Humphreys, and Pat Hanrahan garnered a 2014 Academy Award for Scientific and Technical Achievement from the Academy of Motion Picture Arts and Sciences based on the knowledge shared in the first and second editions of the book this book. The Academy called the book a “widely adopted practical roadmap for most physically based shading and lighting systems used in film production.”

    Additionally you can still buy print (and digital) copies on Amazon via this affiliate link, should you desire the feeling of paper in your hands.  This is not an easy text, and isn’t required reading for everyone, but if you are working on rendering technology or want a peek behind the curtain this is definitely a book you should check out today.
