⭐Game Engine Gems 2 is the second book in a series from editor Eric Lengyel, one of the premiere game engine developers in the scene. I read the first book and I will say this second volume is even better in my opinion. There are a vast number of topics covered, and I found the depth in most of them to be thorough, considering that this is a gem collection and not a full book. Inside there 31 chapters, each from a different author, and a lot of ground is covered. Chapters include: bounding boxes, volumetric clouds, night vision, deferred shading, OpenGL tricks, stereo 3d, web browser 3d, object-oriented design, networked games, GPGPU cloth physics, bit hacks, memory management, multi-threading, and more. Each section was given about 10 to 20 pages, but the authors were concise and were able to explain the concepts well in the short space. I very much enjoyed the wide span of content and I feel this is a text I will look back upon for reference in my own development.While some of the topics were a bit over my head, I did find most of the book to be digestible and relevant. The text would be most apt for people developing their own engines, especially in C++. A few of the early chapters could likely be applied to commercial engines (for example, the sections on volumetric clouds or night-vision shaders) but the the vast majority of the book is focused on more lower-level engine work. I liked that stereoscopic 3d was covered in a few chapters, and the depth was greater than in the first book. The chapters on multi-threading were also very helpful, even though this is admittedly a confusing area for me (I bet I’m not alone). And the section for bit hacks was pretty interesting, which showed some tricks like how to test the sign of a number without branching. Overall, I think this is an awesome book and feel it was somehow overlooked. I would recommend this to any engine developer. Also bought the 3rd book in the series, and I’m looking forward to see how that stacks up.

⭐Once you get past the initial hump of learning how to program, you need to learn how to program games.Even if you’ve been in the business for many years, you may have ended up seeing one, two, or if you’re lucky, three different game engines from the inside.However, this book ties together various nuggets from literally dozens of different game engines, written by the engineers who worked on those engines.Some gems will not work well with your current game, others may be just what you need — however, the real value comes from the education and the illumination of different approaches to solving common problems in game development.Reading a book like this is an invaluable way to grow as a game engine programmer.Disclaimer: I wrote one of the gems, so if you buy this book, I will earn about three cents. That’s not why I think you should buy this book — I think you should buy this book because it will truly expand your game development horizons! That’s also why I contributed in the first place, and I think Eric has done a great job of editing and putting it all together.

⭐So this book contains different articles about adjacent themes. But I couldn’t found gems. This book only introduces to basics of covered topics.
