The Godot Shaders Bible

As someone with no background in shader programming who has tried to learn shaders countless times, I can say that this book is one of the best ways to learn and understand what shaders are all about.

It's just awesome! A ton of knowledge for a reasonable price. I love it! Thank you for this book!

I love, what You did guys. I'm a forever Godot beginner, and I found the Bible very well written and understandable.

A real treat of a book, it starts with the basics and give you good foundation on how to think when writing shaders, it's really good on explaining the maths throughout the exercises and mostly starts of with the formula and then dissect it in code while explaining the reasoning in steps to successfully create the visual effects therein.

I have really enjoyed working through the exercises and at many points I've had AHA! moments where I gain an deeper understanding of the concepts being handled within the pages of this quite excellent book! I have no problems recommending it to anyone wanting to take a dive into shader programming and technical art.

It's decent enough for the price, but 1/4 of the book is about using a graphing calculator to build shapes (which might be of interest to some, but constructing equations to try to get shapes is pretty niche compared to just using vector drawing software!). It's mostly a cookbook approach: code, description of what that code is doing, screenshots of project folders and other padding. There aren't many practically-useful effects or techniques here, unfortunately. Best used in conjunction with better teaching material (e.g. OpenGL guides, non-Godot shader courses and maybe shadertoy examples), this is more "how to implement effects you learned elsewhere specifically using Godot shaders".

An absolute masterpiece. The book explains not only shaders step by step, but also how images are rendered in general, what 3D objects are made of, how they can be created without apps, and the mathematical models involved. The best part for me is that it's all explained in simple language with practical examples.

I think the book gives a good overview over some key concepts but is quite superficial in explaining. It's definitely not for beginners, I did know some stuff beforehand but some concepts like Matrices etc I had to look up other sources. 

Honestly don't really know who this book is for exactly, for people who are comfortable with the topic this is probably not much new (maybe with a few exceptions) and for people who are beginners they will have a bad time.

I also feel the book could be shortened (if it stayed this superficial) since every chapter the author starts explaining how to make a certain folder structure which I didn't really understand why it was explained in such small steps with the rest being so superficial...could have been done once and then omitted, would have probably saved a lot of pages...

The topics themselves are cool and practical though, could have used some more interesting real production examples but I think there is some good stuff here definitely. 
The price is a bit too much especially since it's digital only. 
I would have wished more in-depth explanations of the complex topics.

Still giving 3 stars since the author did put some effort into presentation and some topics are pretty cool, just wished more in-depth and why certain things are they way they are. You don't really learn from "step by step" tutorials....
