> I dislike "Physically Based Rendering: From Theory To Implementation", I personally think that the literate programming approach of the book is way too confusing and disorganized.

Interesting. Personally it's by far the best programming related book I've read. I didn't mind the literal programming, and I loved how it dove fairly deep into the math and physics but also into the details of implementing the math.

The latter being important as there are can be so many gotchas when implementing math.

I agree with OP and find the literal programming in that book incredibly distracting and annoying. I prefer the theory up front and the code later. "Ray Tracing From the Ground Up" does a much better job in my opinion (although it also only covers a fraction of the topics in the PBR book.)
