HoloMinecraft

Minecraft as a real-world hologram. No glasses required.

Hardware Requirements

• Looking Glass holographic display

Software Requirements

Server

• Minecraft Java Edition with Optifine
• Python 3 with the following modules mss, pywin32, opencv-python, diff_match_patch
• Windows (while this could be made to work on any OS, the window-identification part of the screen recording code is currently tailored for Windows)

Client

• [Optional] HoloPlay service (HoloMinecraft is using a patched version of HoloPlay.js to allow HoloPlay-service-less operation.)
• Web browser (If your client is an iOS device, use this custom browser)

See it in action here and here.

Setup

• If you plan on using HoloMinecraft without the HoloPlay service with hardcoded calibration values, get yours here and use them to replace my values on row 55.
• If you are using a single computer as both server and client, you might have to reduce FPS on row 40, reduce the size of your Minecraft window, or both. I recommend using a PC as a server and an iPad as a client for best results.

Steps

1. Put the DepthExtractor folder into your shaderpacks folder (e.g. C:\Users\Username\AppData\Roaming\.minecraft\shaderpacks\)
2. Enable the DepthExtractor shader in Minecraft (Options… -> Video Settings… -> Shaders…)
3. Run holominecraft.py
4. Open http://localhost:9090/holo.html in your browser, move the window to the Looking Glass display and enable Fullscreen.
