A multi-threaded mapper for Minetest with node transparency support.

It generates a view of the world from above, rendering one pixel per voxel.

Crates.io Dependency Status

Usage

First, compile the project with cargo:

cargo build --release

Then, call the executable target/release/minetest-worldmapper with the three required arguments:

Option Short Description
--world -w The directory of the world to render.
--config -c The config file. The format should follow the example config file.
--output -o The image file which the map should be rendered to.

Example usage

minetest-worldmapper --world TestWorld/ --config config.example.toml --output map.png

Config file

If a voxel is rendered and its color are entirely determined by the config file. Its main purpose is to map content IDs to colors.

Config option Type Description
version Integer Config version. Currently always 1.
background_color String Hex color string in the format "rrggbb" or "rrggbbaa". Serves as a fallback color if all voxels for a given pixel are exhausted and there is transparency left.
target_alpha Integer When determining a pixel's color, stop going through transparent nodes when reaching this opacity value. Between 0 and 255.
node_colors Table A mapping from content names to color strings in the same format as background_color.

Current limits

  • Only sqlite3 is supported as backend.
  • Only map chunks with map format version 29 (the current) are supported.
