# Utils for map creation, conversion, 3d models and related stuff
|
|
|
|
Note:
|
|
|
|
- EVERY SCRIPT THAT USES REDIS IS JUST AS REFERENCE (node-redis and keys update and change over time and i am not keeping those up-to-date)
|
|
- we use blender 2.8
|
|
- js script are executed with `npm run babel-node utils/[scriptname].js`
|

## sphere-protection.blend
|
|
This blend file includes the sphere we use to display the globe with two UV maps, one for protection like it's used on many globe textures of the earth like [here](http://blog.mastermaps.com/2013/09/creating-webgl-earth-with-threejs.html) and [here](http://www.shadedrelief.com/natural3/pages/textures.html) and one for our mercator projection that is the same as on OpenStreetMap, with additional changes for poles.
|
|
The shader nodes in the bumpmap material are setup so that they bake from one uv map to another.
|
|
|
|
If you want to generate the .glb model file for the site thats in public/globe/globe.glb:
|
|
1. delete all materials of the sphere
|
|
2. delete the "fake-mercator" uv map, so that just the mercator one is left
|
|
3. create a new one without textures
|
|
4. name the material "canvas" (this will then be set by the script to the canvas textures)
|
|
5. select the sphere and export as .glb
|
|
|
|
## ocean-tiles
|
|
Used to generate tiles based on a uv texture that can then be drawn on the canvas, like the oceans and continents.

|
|

Generates a json list of country codes and their coordinates on the canvas based on lat and lon

Script to move canvas chunks, i.e. for resizing canvas
|
|
|
|
## areaDownload.py
|
|
downloads an area of the canvas into a png file.
|
|
Usage: `areaDownload.py startX_startY endX_endY filename.png`
|
|
(note that you can copy the current coordinates in this format on the site by pressing R)
|
|
**Requires:** aiohttp, asyncio and PIL python3 packages
|
|
|
|
## historyDownload.py
|
|
downloads the history from an canvas area between two dates.
|
|
Useage: `historyDownload.py canvasId startX_startY endX_endY start_date end_date
|
|
This is used for creating timelapses, see the cmd help to know how
