DESCRIPTION:Over 10 years ago\, the French Institute of Geographic Informat
 ion (IGN) created "Minecraft on demand"\, a web service that uses real geo
 graphical data to build playable worlds for voxel games such as Minecraft 
 (worlds made of small unit cubes). After 135\,000 voxel world generations\
 , including more than 6\,000 from OSM data\, the service turned out to be 
 limited\, missing flexibility and using only a small fraction of OSM data.
  The institute capitalized on its experience to design a new standalone an
 d flexible tool able to exploit the full richness of OSM data and much mor
 e.\n\nAs many generation constraints as possible have been removed. For in
 stance\, size of created world is only limited by game format and not anym
 ore by memory size. The extremely high configurability makes this tool ver
 y versatile. Decisions are driven by the user’s creativity and not by th
 e software. All the tasks\, ranging from data loading\, processing\, all t
 he way to rendering are described through a human readable configuration f
 ile\, so that even non-programmers can easily fine-tune their pipeline. Th
 is new tool can be seen as the "Swiss Army knife" of geographical data vox
 elization (conversion of data into voxel worlds).\n\nThe tool is open sour
 ce\, modular and can be extended with Java modules. It paves the way for n
 ew community-maintained features\, such as support for new geographical da
 ta formats\, processing algorithms\, or voxel formats. Consequently\, the 
 tool has the potential to natively manipulate any type of data (vector\, r
 aster\, point cloud...) originating from any provider (OSM Overpass\, OGC 
 WFS/WMS\, local files...)\, process it in various ways\, and create any vo
 xel-based format as a result (Luanti\, Minecraft\, Lego...). For instance\
 , it is possible to create a Luanti world with terrain elevation imported 
 from OpenDEM\, and any feature from OSM (road network\, buildings\, land u
 se...).\n \nWhile most of the existing tools are focused on "fun" or educa
 tional usages\, this one makes no assumption about the user's intent\, and
  can be used for any purpose\, including:\n- Immersive exploration (e.g. f
 or citizen participation)\n- Rebuild in context (e.g. of a monument)\n- Th
 ematic rendering (e.g. based on a tag such as restaurant's cuisine)\n- Mix
 ing/custom sources (e.g. with local files)\n- And many more to discover!
