root2gltf

This app converts detector objects from ROOT format to glTF used by Phoenix. It is a quick hack needed to run conversion headless (e.g. in CI).

Depends on JSROOT and Three.js.

Uses also patched versions of the GLTFExporter.js from Three.js and phoenixExport.js from root_cern-To_gltf-Exporter.

Installation

After git clone run:

npm ci

Usage

To run the app in the main directory:

node . detector.root

In order to convert the geometry one needs to write a configuration file. The examples of the configuration file are provided in configs directory. Three variables are expected in the configuration file:

• subParts names of the detector subparts to be given separate element in the phoenix menu
• childrenToHide stems of names of the subparts to be removed
• maxLevel maximum depth of detail
