running tile-converter from 3D Tiles to I3s?

[bertt]

Hi,

I'm trying to run tool tile-converter to convert a 3D Tile tileset to I3s, but only get errors :-(

$  npx tile-converter --input-type 3DTILES --tileset tileset.json --name test

Like : Error: unknown scheme, TypeError: fetch failed. I've run command --install-dependencies. Also with the Docker image no luck.

Questions: Is there a sample dataset where this tool is working on? What 3D Tiles features are supported (1.0/1.1, b3dm/pnts/cmpt/i3dm?)

[belom88]

v1.0 b3dm conversion is supported + some extensions of vNext. For instance, Cesium ION b3dm datasets can be converted. pnts, cmpt and i3dm is not supported by the tile-converter. To help you we need details, eg which OS do you use, NodeJS version? Having the example of the tileset you use would be good as well.

Hi for example on Mac (Node v18.10.0) I did (for https://bertt.github.io/utrecht3d):

$ git clone https://github.com/bertt/utrecht3d.git
$ cd utrecht3d/tiles
$ npx tile-converter --install-dependencies
Installing "EGM2008-5" model...

/utrecht3d/tiles/deps/egm2008-5.pgm saved.
All dependencies were installed succesfully.
$ npx tile-converter --input-type 3DTILES --tileset tileset.json --name test
 tileset.json --name test

One note is that loaders.gl does not yet support Node.js v18. I can't say for sure that the problems are related to that from the above log, but we have just started looking at Node.js v18 and there are a number of issues to be solved, some involving the tile-converter.

Any chance you can try on Node v16? (We use nvm to quickly switch between versions).

ah yes got it now working using Node 16.19! Thanks
