tilesetToDatabase

Generates a sqlite database for a tileset.

This tool cannot be used with the Pipeline tool.

Each tile is stored gzipped in the database. The specification for the tables in the database is not final, see 3d-tiles/#89.

node ./bin/3d-tiles-tools.js tilesetToDatabase ./specs/data/TilesetOfTilesets/ ./output/tileset.3dtiles
node ./bin/3d-tiles-tools.js tilesetToDatabase -i ./specs/data/TilesetOfTilesets/ -o ./output/tileset.3dtiles

-o, --outputOutput path of the resulting .3dtiles.No
-f, --forceOverwrite output file if it exists.No, default false

databaseToTileset

Unpack a tileset database to a tileset folder.

This tool cannot be used with the Pipeline tool.

Each tile is stored gzipped in the database, and unzipped when unpacked. The specification for the tables in the database is not final, see 3d-tiles/#89.

node ./bin/3d-tiles-tools.js databaseToTileset ./specs/data/tileset.3dtiles ./output/Tileset
node ./bin/3d-tiles-tools.js databaseToTileset -i ./specs/data/tileset.3dtiles -o ./output/Tileset
FlagDescriptionRequired
-i, --inputInput .3dtiles database file.:whitecheckmark: Yes
-o, --outputOutput directory of the unpacked tileset.No
-f, --forceOverwrite output directory if it exists.No, default false

Pipeline

node ./bin/3d-tiles-tools.js pipeline ./specs/data/pipeline.json
node ./bin/3d-tiles-tools.js pipeline -i ./specs/data/pipeline.json
FlagDescriptionRequired
-i, --inputInput pipeline JSON file.:whitecheckmark: Yes
-f, --forceOverwrite output directory if it exists.No, default false

Executes a pipeline JSON file containing an input directory, output directory, and list of stages to run. A stage can be a string specifying the stage name or an object specifying the stage name and any additional parameters. Stages are executed in the order listed.

This example pipeline.json gzips the input tilest and saves it in the given output directory.

{
    "input": "Tileset/",
    "output": "TilesetGzipped/",
    "stages": ["gzip"]
}

This pipeline uncompresses the input tileset and then compresses all the tiles. Files like tileset.json are left uncompressed.

{
    "input": "Tileset/",
    "output": "TilesetGzipped/",
    "stages": [
        "ungzip",
        {
            "name": "gzip",
            "tilesOnly": true
        }
    ]
}

Pipeline Stages

gzip

Gzips the input tileset.

Properties

TypeDescriptionRequired
tilesOnlybooleanOnly gzip tiles.No, default: false

ungzip

Build Instructions

Run the tests:

npm run test

To run JSHint on the entire codebase, run:

npm run jsHint

To run JSHint automatically when a file is saved, run the following and leave it open in a console window:

npm run jsHint-watch

Running Test Coverage

Coverage uses istanbul. Run:

npm run coverage

For complete coverage details, open coverage/lcov-report/index.html.

The tests and coverage covers the Node.js module; it does not cover the command-line interface.

Generating Documentation
