Video Game Blurs (and how the best one works)
How to build realtime blurs on the GPU and how the best blur algorithm works - "Dual Kawase"
Using the GPU in the device you are reading this article on, and the WebGL capability of your browser, we’ll implement realtime blurring techniques and retrace the trade-offs graphics programmers had to make in order to marry two, sometimes opposing, worlds: Mathematical theory and Technological reality.
