Short version: see new book releases here.
Long version: All credit goes to Ibrahim Belabbaci for bringing these new books to our attention. Beyond Ray Tracing Gems II, he sent on five new titles released since June. One’s entirely free to download, and there are nice long excerpts of the rest on Google Books. You’ll see all the links on our page.
I was particularly happy to see that Lee Stemkoski coauthored the free one, Developing Graphics Frameworks with Python and OpenGL. Years ago he put up a marvelous website of three.js demos with clean source code, showing how to do each operation. It’s also nice to see that MIT Press is publishing more books on computer graphics. Anyway, go take a look at the updated page. Covers below.
