Ira Greenberg’s "Processing: Creative Coding and Computational Art" (published by Friends of Ed) was the first Processing book to hit the shelves this fall. I haven’t had a chance to look at it in Person, but from the sample chapters provided it looks very useful.
“Appendix C: Integrating Processing within Java” should be of interest to anyone looking to better understand how Processing and Java work together. It breaks down the basics of how pure Java syntax differs from Processing, and shows how you can make the switch quite easily. It wraps up with a useful example of how to write a Swing GUI application with a Processing sketch as a GUI Component.
The two other sample chapters deal respectively with 3D rendering (including a quick introduction to vector math) and drawing more complex shapes. You can download all of them from the Friends of Ed site, where you can also buy the book in hardcopy or ebook form.
