Mapcrafter

For Minecraft 1.13, see issue #113. TL;DR: Minecraft 1.13 support is pretty much complete, few small features and full documentation are still in progress. Can be built from source from world113 branch or nightly packages can be used.

by Moritz Hilscher

Due to my university studies and other projects, unfortunately I'm not able to develop new features for Mapcrafter anymore. I'll try to keep up with the issues on GitHub from time to time, so if you're experiencing a problem, don't mind reporting it. You can still submit feature requests in case I or someone else decides to do some work on Mapcrafter. I'm happy about PRs too. If you want to work on Mapcrafter and need help with something just ask me (Mail, IRC, GitHub), I can tell you a bit about how the project is structured.

Mapcrafter is a high performance Minecraft map renderer written in C++. It renders Minecraft worlds to a bunch of images which are viewable in any webbrowser using Leaflet.js.

Mapcrafter is free software and available under the GPL license. You can access the latest source code of Mapcrafter on GitHub: http://github.com/mapcrafter/mapcrafter

Thanks to pigmap and Minecraft Overviewer, whose documentations and source code were very helpful. I also used the alpha blending code of pigmap and some maps stuff of the template from Minecraft Overviewer.

Features

• Web output: Render your Minecraft worlds to maps viewable in any webbrowser!
• Different render views: Choose between different perspectives to render your world from! A 2D topdown and a 3D isometric render view are available!
• Different rotations: Choose from four different rotations to render your worlds from!
• Different render modes: Choose between different render modes like day, night and cave for your maps!
• Different overlays: Show additional information on your map! For example: Where can slimes spawn? Where can monsters spawn at night?
• Configuration files: Highly-customizable which worlds are rendered with which render view and other render parameters!
• Markers: Automatically generated markers from your Minecraft world data!
• Other stuff: Biome colors, incremental rendering, multithreading

Requirements

• A Linux-based or Unix-like operating system like Mac OS
• A decent C++ compiler (preferable gcc >= 4.4, or clang), CMake and make if you want to build Mapcrafter from source
• Some libraries:
  • libpng
  • libjpeg (but you should use libjpeg-turbo as drop in replacement)
  • libboost-iostreams
  • libboost-system
  • libboost-filesystem (>= 1.42)
  • libboost-program-options
  • (libboost-test if you want to use the tests)
• For your Minecraft worlds:
  • Anvil world format
  • Minecraft 1.6 resource packs

Examples

There are a few example maps of the renderer on the GitHub Wiki. Please feel free to add your own map to this list.

Documentation and Help

The documentation is in the docs/ directory and you can build it yourself with Sphinx. You can read a built version of the documentation on docs.mapcrafter.org and you can also download other builds.

If you find bugs or problems when using Mapcrafter or if you have ideas for new features, then please feel free to add an issue to the GitHub issue tracker.

You can contact me in IRC (#mapcrafter on Freenode). Use the webclient if you are new to IRC. I will be there most of the time, but please bear in mind that I can't be available all the time. If I'm not there, wait some time or try another time of the day.

You can also ask questions in the Minecraft Forum thread.
