WebGL GLSL SAO (Scalable Ambient Obscurance) fragment shader. SAO is a more efficient method for computing SSAO (Screen-Space Ambient Occlusion). Converts the g-buffer to an occlusion buffer which estimates local ambient occlusion at each fragment in screen-space. For details on the technique itself, see: McGuire et al [12] http://graphics.cs.wi…
// total number of samples at each fragment
#define NUM_SAMPLES {{ numSamples }}
#define NUM_SPIRAL_TURNS {{ numSpiralTurns }}

git hook to run a command after `git pull` if a specified file was changed.In this example it's used to run `npm install` if package.json changed and `bower install` if `bower.json` changed.Run `chmod +x post-merge` to make it executable then put it into `.git/hooks/`.
