Simon Yeoung posted a nice article on his blog on his implementation of voxel cone tracing.
NVIDIA posted a great article on their site on why to use pre-multiplied alpha called Alpha Blending: To Pre or Not To Pre. A longer, more in-depth treatise of the same subject was posted in 2006 by Tom Forsyth, a worthwhile read.
Steve McAuley has a short post on his blog that builds on a previous post he did on making the often used wrapped diffuse model energy-conserving. In this new post, he extends the formula to a generic wrapped diffuse model where an arbitrary power is used to soften the look a bit. His post is called Extension to Energy-Conserving Wrapped Diffuse.
Here's a nice blog post comparing NVIDIA's FX Composer to Unity when it comes to quick shader prototyping.
Google released a C++ library called cpp-btree, which provides an STL-style implementation of B-tree data structures.
Another one of Herb Sutter's talks at C++ and Beyond 2012 got released on Channel 9. atomic Weapons: The C++ Memory Model and Modern Hardware is a two-part talk on the new C++11 memory model. This is a must-watch if you're doing any work on lock free algorithms. Great, in-depth talk.
After having done code reviews of the various open sourced id Software code bases, Fabien Sanglard is back with a review of the code of Duke Nukem 3D.
