Marwan Ansari has put out a call for participation for “Game Development Tools 2”. Proposals are due July 1, for publication around SIGGRAPH 2014. Among other things, Marwan’s the author of some wonderful (old but still useful) comprehensive articles on GPU image processing, freely downloadable in the “ShaderX^2 Tips and Tricks book”.
You can use Amazon’s Look Inside feature to see some of the first book in the “Game Development Tools” series, and the demos for the first book are also available.
