Physically Based Rendering: From Theory to Implementation, authored by Matt Pharr, Wenzel Jakob, and Greg Humphreys, is a comprehensive textbook that explores the principles and practical applications of photorealistic computer graphics. The updated edition emphasizes physically based rendering techniques, which accurately model light scattering to achieve visual realism and predictability in image synthesis. The book integrates mathematical theory with practical implementation, utilizing a literate programming approach that combines documentation and source code for enhanced understanding. It includes advanced algorithms and new content on GPU ray tracing, enabling readers to develop sophisticated rendering systems. The authors received a 2014 Academy Award for Scientific and Technical Achievement for their contributions to the field, with the book recognized as a crucial resource for physically based shading and lighting in film production. Donald Knuth praised the work, suggesting it deserves a Pulitzer Prize. Both the third and fourth editions of the book are available for free online, making this essential text accessible to a wider audience interested in the future of real-time graphics.

8 commentsThere are applications (Zemax, for example) that are used to design optical systems (lens arrangements for cameras, etc). These applications are eye-wateringly expensive-- like similar in pricing to top-class EDA software licenses.
With the abundance GPU's and modern UI's, I wonder how much work would be involved for someone to make optical design software that blows away the old tools. It would be ray-tracing, but with interesting complications like accounting for polarization, diffraction, scattering, fluorescence, media effects beyond refraction like like birefringence and stuff like Kerr and Pockels, etc.
There's often a lot of details that matter when implementing something efficiently and well which the theory either hides or is a result of our hardware limitations like floating point numbers.
Almost all other programming books I've read cover either the theory in detail and gloss over the implementation details, or goes into a lot of implementation stuff but only cover the easy parts and doesn't give you a good indication of how to deal with the advanced stuff.
So, any other books out there that you've read that is like PBR?
but the algorithm for the theory looks approximately like this to me

I've wanted to add this capability to Solvespace for a while. I did my own implementation with the Fresnel term and it looked OK, but I want something "standard" and correct.
