bluemap-full-render

Made with node-canvas, headless-gl and regl with WebGL shaders stolen from bluemap repository

Usage

1. Clone repository
2. Install nvm.sh
3. Execute nvm use (node.js v20.13.1 should be installed, confirm with node -v)
4. Execute npm install (check requirements here: headless-gl)
5. Execute npm run build
6. Download /bluemap/web/maps/overworld/tiles/1 to some folder and rename to bluemap-[date]
7. Execute node out/index.js ./path/to/bluemap-[date] ./my-output-directory where first argument is path to the folder you downloaded in step 6 and second argument is path to the output directory

This will output map parts with resolution 1:1 block and size of 16384х16384 pixels that you can stitch together to get a final ultra big map.

Bluemap API

For reference only, not needed to run this program

https://map.yourserver.com/maps/overworld/tiles/[zoom level]

Bluemap can't count to 10. Only 0 to 9 both ends included.

/x[actual X tile index from 0 to 9]/z[actual Z tile index from 0 to 9].png

If we need to go further:

/x[first digit from 0 to 9]/[second digit from 9 to 0]/z[actual Z tile index from 0 to 9].png

Another example:

/x[X tile index 0 to 9]/z[first digit from 0 to 9]/[second digit from 0 to 9].png

• Zoom level 0 = json files for rendering in threejs
• Zoom level 1 = 1:1 (1 block = 1 pixel)
• Zoom level 2 = 4:1 (4 blocks = 1 pixel)
• Zoom level 3 = about 20:1 (20 blocks = 1 pixel) (?)
