Simple 3D Tiles Viewer

Cesium viewer for testing local tileset.json trees, with a nix run launcher that serves the current directory with CORS.

Usage

From any directory containing a tileset.json:

nix run github:3dgi/tv

To force a rebuild of the viewer app:

nix run --refresh github:3dgi/tv

This is only necessary if this repo had an update.

Optional flags:

nix run github:3dgi/tv -- --port 8090 --tileset path/to/tileset.json

Local development

Run from the local repository:

git clone git@github.com:3DGI/tv.git
cd ./tv
nix run .

To force a rebuild of your local checkout:

nix run --refresh .

Run from a directory containing tileset.json:

cd /path/to/tileset-dir
nix run --refresh ./tv

Serve a tileset from a different directory:

nix run --refresh ./tv -- --tileset /path/to/tileset-dir/tileset.json

Optional flags:

nix run --refresh ./tv -- --port 8090 --viewer-port 8091 --tileset /path/to/tileset.json

The command starts a local static server with permissive CORS headers and prints:

• the local tileset URL
• a local viewer URL

The viewer includes a Terrain selector with three modes:

• None
• Cesium World Terrain (requires a Cesium Ion token)
• PDOK Quantized Mesh via https://api.pdok.nl/kadaster/3d-basisvoorziening/ogc/v1/collections/digitaalterreinmodel/quantized-mesh

The selected terrain mode is persisted in the URL as the terrain query parameter.
