Free Ray Tracing Gems Book

Finishing in hard cover form just in time for GTC 2019, NVidia and APress have team up to author Ray Tracing Gems, a book on real-time raytraced graphics development in the popular “Gems” format.  Even better, they are making digital chapters available as they are developed, free to those with a NVidia developer account (which is also free).  The chapters are distributed under the Creative Commons 4.0 International License and are available for download here.  Unfortunately Part 5 is currently missing and parts 6 and 7 are slated to be published later this week.
