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  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.

Over on the Construct2 blog there is this announcement of a new free e-book Level Zero about programming games from scratch using Construct2.


This recently published book "Level 0" is a resource designed for the absolute beginner. You'll learn how to set up characters and backgrounds, apply in-game mechanics and implement if – then functions and end up with five fully functional mini-games. The book will also show you how to publish your games to app stores and make them available to millions of potential customers around the world. The goal of Level 0 is to give aspiring game developers the basic building blocks to apply their creativity and bring their vision to life. For example, one of the mini-games you’ll learn to build is a simple sound board app where you click on an image and the corresponding sound will play. Through this exercise, not only do you pick up the skills to build a virtual keyboard or maybe an educational app that teaches kids the sounds farm animals make but also learn how to use sound, music and touch functions that can be used for subsequent arcade and action games. Each of the 5 mini-games covered in the book has already been used by thousands of Construct 2 users to build their first game on Construct 2.

This book uses Construct 2 in all the featured tutorials. According to the authors,"Construct 2 is as easy as it gets for making a game". Spot on!

C'mon, gimme the download link!

It's available on for a little over $3 USD, however we've managed to get permission to distribute it for free on Scirra for now!

Download for Free

(Right click and "Save Link As")

And good news, Ankur tells us that there's a second book in development detailing how to build 3 classic arcade games. Keep your eye out!


So head on over to the Scirra blog to download a free copy, or support the authors by purchasing it on Amazon.

Over the past couple months I have been working on a series of posts covering MonoGame with the intention of compiling them into an e-book when finished.  There have been a few preview builds of the book available to Patreon supporters (thanks by the way!).  Now however I consider the series to be complete so I am making the book available to all.  I will eventually be creating a more complete and formal homepage for the title but this one should work in the meantime.


Truth of the matter is, I had intended to cover a great deal more on the subject, but the level of traffic simply doesn’t justify the further expenditure of time.  That said, I leave the book at a state I think it should prove useful for anyone getting started in XNA or MonoGame game development, it is as comprehensive as any beginner XNA book currently available.  The book is composed of seven chapters:


Chapter One

An Introduction and Brief History

Book Cover

Chapter Two

Getting Started with MonoGame on Windows

Chapter Three

Getting Started with MonoGame on MacOS

Chapter Four

Creating an Application

Chapter Five

2D Graphics

Chapter Six

Audio Programming

Chapter Seven

3D Graphics 




Of course, the tutorials based here on GameFromScratch are still going to be available in addition to this PDF.  There is also a complete video tutorial series to go along with each chapter in the book available here.


With today’s release of the book, I also have published a github repository containing all of the source code used in the book.  This is a single Visual Studio solution containing each example as a separate project.  For some reason I don’t quite understand, all of the chapters are mismatched by one.  So for example the code in Chapter 8 on Github actually corresponds with Chapter 7 in the book.  Oops.


Alright, enough blathering, here is the book in PDF format.  I can make it available in other e-reader formats if requested.

EDIT: Here is an untested epub version of the book.

EDIT2: Now it has been posted on Smashwords as well, which should ultimately make it available from a number of sources.
