dictionary – Can you use the worldmap plugin in node-red to view a building in 3D?

admin

I am trying to use the “worldmap” plugin in node-red to display a 3D building in Barcelona, Spain that I’ve constructed from polygons using coordinates from the following source (which also shows what the building is supposed to look like): bl.ocks.org/sigon426/11283563

The problem is that I can only see it in 2D, as in the following screenshot: i.stack.imgur.com/Kftv0.png

The documentation for the worldmap plugin (flows.nodered.org/node/node-red-contrib-web-worldmap) does say something about index3d.html, but when I browse to localhost:1880/worldmap/index3d.html instead of localhost:1880/worldmap/index.html, I get a completely blank page, with no map at all. I confirmed that this is NOT due to a typo, because if I intentionally insert a typo, I get an error message. Per the documentation, I also tried using my own API key (per the documentation), but that did not help, either.

Has anybody ever gotten a building to render in 3D, and if so, would you mind sharing your code and/or how you got index3d.html to not be a blank page?

node-red code is below:
