NVIDIA recommended four books, but only half of them are published in China.
I owned <GPU Gems> and <The Cg Tutorial>'s chinese translated version.
The <GPU Gems> have many authors, it's translators have many either. the different experiences of these different translators caused this book have many translation style, that's a big weakness of this nice book.
These days I'm hanging on the <The Cg Tutorial>, even if it's a quite old book( published in 2004), but the old cannot cover it's brilliance, the same as <GPU Gems> it's blemish is translation, many glossaries is wrong.
