I just learned of a new book coming out: “Real-Time Shadows“, by an excellent group of researchers (a little more info here). I assume this book will be based on the authors’ 148-page “Casting Shadows in Real Time” course notes and related publications. This subject deserves its own book. There are enough interesting principles and so many variants and subtleties that I’m happy to hear this topic will get thorough coverage. Our book page is updated.

Looking around at other book-related resources, I noticed some interesting bits. John Vince’s “Geometry for Computer Graphics: Formulae, Examples and Proofs“, from 2005, has been reissued in a softcover edition. It’s pricey, as Springer books can be, and weighs in at just 364 pages, but it’s an information-packed volume. It’s a kind of book you rarely see now, one with a dense collection of formulae, like CRC Press used to specialize in. Google Books sample here. Some of it’s pretty tangential to computer graphics – normally I don’t need proofs about things like the opposite angles of a parallelogram being equal – but it’s fun to page through: “Someday I’d love to find a use for that coiled ring equation”. Whether you’ll ever need 1/100th of the information in this book depends on you. It seems like a good fit for demoscene programmers who want procedural functions and model generation, for example. Anyway, something to see if your university library has, just to page through and know it exists.

Speaking of geometric resources, I was sad to see the site appears to be defunct. What’s key to remember in such cases is that there’s the Wayback Machine. Just put in a dead URL and more times than not this site will have a copy. So the Geometry Algorithms site lives on here! Luckily, math doesn’t really rot, so the articles are still worthwhile. The bad news is that a few of the figures are missing.

For technical book authors, I ran across this interesting little tool: Detexify2. Draw the symbol you need, it will show you likely matches and what LaTeX you need. I’ve found it’s pretty accurate, though seemed to have problems with “not equals” half the time I drew that symbol as a test. Anyway, it’s probably no more efficient than just looking it up here or here, but is more fun.

Last resource for the (mothers’) day: so you want to explain the basics of computer graphics to your mom. Frédo Durand’s six page introduction is not a bad place to start. At the least, you can use the figures at the end to explain ideas.
