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.

• Web output: Render your Minecraft worlds to maps with an isometric 3D perspective viewable in any webbrowser!
• Different directions: Choose from four different directions to render your worlds!
• Different rendermodes: Choose between different rendermodes like day, night and cave for your maps!
• Configuration files: Control which worlds are rendered from which direction and with which rendermodes!
• Markers: Automatically generated markers from your Minecraft world data!
• Other stuff: Biome colors, incremental rendering, multithreading

• 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

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

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.
