WebGL GLSL HBAO (Horizon-Based Ambient Occlusion) fragment shader. HBAO is a higher quality approach for computing SSAO (Screen-Space Ambient Occlusion) developed by Nvidia in 2008. Converts the g-buffer to an occlusion buffer which estimates local ambient occlusion at each fragment in screen-space. Specifically, the technique views the depth bu…

I use the QNAP nas server to host docker containers. We can configure

This is how we set that up:
docker-machine create --driver=none --url tcp://<your qnap box>:2376 qnap
Next we need to install the certs. Download them from within the QNAP
