Here are some cool blogs I've come across recently. Virtual Globe and Terrain Rendering is devoted to a book-in-progress of the same name and has a nice collection of links to resources and other interesting blogs. RasterGrid has good articles on new features of OpenGL; I especially like Instance Culling Using Geometry Shaders, about doing culling on the GPU, and Uniform Buffers vs Texture Buffers. For an old graphics fossil like me, these are great topics in modern 3D graphics programming. Also, the Outerra engine guys are doing cool stuff and writing about it too. I've added these to my blog list, and so should you!

Here's part 2 of my articles on Open Scene Graph graphics state management. Part 1 covered the
StateSetclass, which OSG programmers should be familiar with. This part looks behind the scenes at how the OSG "backend" optimizes rendering for minimizing graphics state changes. Enjoy!
