About This
- 【Upgrade Version】This fish tank light is an upgraded version, with a larger size of lamp beads and a shiny surface that is bigger and more stable. It won't hurt your eyes when you look at your fish tank. The retractable stand measures a maximum of 6 inches and fits most freshwater tanks with and without lids. The aluminum housing with grooves provides excellent water resistance and heat dissipation
- 【24/7 Natural Mode】The Aquarium Light has a lighting pattern that can simulate sunrise to night. By default,the aquarium lights change to gold yellow from 6 am to 8 am, change to white after 8 am, and then gradually change to blue from 6 pm to 10:50 pm, remaining off the rest of the day. You can use the 24H button + 6 time point indication to set the first running time. By default, it turns on at 6 o'clock, and the whole time period can be advanced or delayed
- 【Customization Mode】You can set the light's color, time, and brightness according to your needs. There are eight color settings, white, red, green, blue,purple,gold yellow, cyan, and cycle. In addition, you can set your running time to 6H/10H/12H, respectively. With five brightness levels, you can adjust the brightness from 10%-100% and long press for stepless dimming
- 【High-Quality Lamp Beads】The fish tank light adopts high-quality 5730+5050 type lamp beads, so the light is more stable, with no strobe. With 85% of the color rendering index is close to natural light, bringing better light perception for fish and your eyes. The lamp beads are made of glue-filled technology, with an acrylic baffle to prevent water vapor from entering, making it more waterproof and extending its service life

There's nothing else out there that's this comprehensive
Format: Hardcover
Unlike my last review, this one I'm happy to write. I'm a game engine programmer, but I don't have a long history with games, and how their engines are typically structured. Every in-house AAA engine will be different of course, and obviously you won't find books (or typically any docs at all really) on the structure of these behemoths, so the best you can hope for is something that tries to give you the high level overview of what to look for - how a tools pipeline is setup, what subsystems to expect, how they interact, etc.
This book provides all of that, and so, so much more. I really can't believe how much is packed in this thing. A really nice section on OS fundamentals, extensive coverage of concurrent programming, tools, audio, physics, it's all there (in one way or another). Like most of these kinds of books, you probably don't want to try and read it front to back (although that would be awesome, who has the time for that?) Instead, I've been going to sections on an as-needed basis and picking up just the stuff I need most at that time, and it's been great.
I'm at the point in my career where I'm just not buying as many books as I used to, either because they don't deliver on their promises, they only cover the basics, or they just rehash things that have already been covered extensively in other books. This book's definitely got me excited, because it provides a ton of real-world info that's hard to get anywhere else. 100% recommend to anyone new to game engine software development.
UPDATE: 6 months later, and this book continues to amaze. After studying every line of code in the section on memory allocators, I've added this feature to my engine and it works great. Same with quaternions. I just keep finding myself reaching for this book! What a great resource, rock solid.

Don't peek at the next page.
Format: Hardcover
Basically, best practices in game engine architecture, citing a wide array of game engines used by a wide array of top game makers.
Out of a ~1150 page book:
The longest chapter is ~150 pages, on Parallelism and Concurrent Programming.
Rendering Engine is ~100 pages
Collision and Rigid Body Dynamics is ~100 pages
3D Math for Games is ~50 pages
I had hoped for treatments on quaternion camera and for entity component system, but alas, no.
What I did get was still crucial. The most illuminating guidance was in Engine Support Systems (~50 pages) which talked about best Memory Management, and in Game Loop and Real-Time Simulation which talks about ideal orders of operations in a highly efficient game loop.
The first 400 pages of this book are not exclusive to games. A new programmer that wants to do high performance programming can gain a lot from this before it gets into 'primarily' game topics.
My strategy for getting through this whale was to never peek at the next page. I did not read (Character) Animation Systems (~100 pages) or Audio (~100 pages), as I do not need them at this time.
You can certainly damage the book if you don't keep in mind its weight, or if you do that maneuver where you forcibly open it against its spine. I did that and the binding popped off the backing. It's all in one piece, and it's easier to read. It's a big tome.

The Bible, if it was good
Format: Hardcover
I’m not kidding when I say the first 350 pages of this book are quite literally an entire computer science degree. In fact, many CS majors would learn more about some of these subjects here than in their classes. I’m incredibly impressed with the thoroughness and depth of this absolute tome, and I’ll be far more impressed if the binding is able to hold on to all 1200 pages for the whole time it takes me to read it.

good quality
Format: Hardcover, Format: Hardcover
Content is top notch as always. My 5-stars go mainly to reflect print quality of the book. Text is nice and clear, binding is done in proper cloth spine binding as you would expect from hardcover edition. Ordered my book on Feb 5th, 2019 and received it on Feb 11th, 2019. The book feels solid not like to fall apart right away. No issues like those reported for "Real-Time Rendering, 4th Edition" or "Physically Based Rendering: From Theory to Implementation 3rd Edition" or "3D Math Primer for Graphics and Game Development, 2nd Edition". This one is a keeper, so sad some other CG books had to go beacuse of the quality "issues".
