Matt, Greg, and I are super-excited to release a free online edition of the Physically Based Rendering Book with hyperlinked cross-referencing, beautiful SVG figures and equations as well as interactive image comparisons. The details of how all of this came to be are explained in the preface to the online edition. (

Thank you for this detailed description. I will definitely take a look and read a few chapters about the light transport.
Just a remark. When I first read the title, I was interested in the approximations you use because you emphasize physics so much in your book and your title. I read the preface and found a suspicious sentence.
When configured to do so, pbrt can compute images that are physically correct; they accurately reflect the lighting as it would be in a real-world version of the scene.
That is not correct. You use a phenomenological model for the light-matter interaction and approximate the effects of light with raytracing. That still produces (almost) photo realistic images for our eyes, but is not "physically correct". A paragraph on the limitations of technology could be worthwhile.

Ever since I saw this book being sold, I've been eagerly wanting to read it. The physics-based approach is definitely the way I would prefer to learn any subject, and rendering is just one of the areas I wish I knew more about. Delighted to know that you guys put it online, thank you!

This is the book that won Matt Pharr, Greg Humphreys and Pat Hanrahan an Academy Award
https://www.oscars.org/sci-tech/ceremonies/2014
>> To Matt Pharr, Greg Humphreys and Pat Hanrahan for their formalization and reference implementation of the concepts behind physically based rendering, as shared in their book Physically Based Rendering.
>> Physically based rendering has transformed computer graphics lighting by more accurately simulating materials and lights, allowing digital artists to focus on cinematography rather than the intricacies of rendering. First published in 2004, Physically Based Rendering is both a textbook and a complete source-code implementation that has provided a widely adopted practical roadmap for most physically based shading and lighting systems used in film production.

What is the best way to attack this book as a graphics programming beginner (but with plenty of C++ experience)? I saw several people praise it a while back in HN and took a cursory look. It seemed complete and thoroughly explained but missing examples or "checkpoints" along the way where I could turn around and test what I had been building.

what technology have they used to create the website? I'm guessing some pandoc to html workflow plus a static site engine?

This makes me super happy. I bought the book a few years back and always meant to go through it with rigor to build my own renderer. Now I have that free time but as a digital nomad, I couldn't bring the book. (its up there in size).

Thanks for putting this online, my physical copy is currently buried in storage and I’ve been dying continue reading it!

I got my physical copy a few months ago, glad to see more people having access to this great resource now!

Thank you so much. I love my physical copy but can't always take it with me places.
