    Loading glTF 2.0 Models

    The glTF 2.0 Loader extension provides the ability to load glTF 2.0 models in the viewer.

    The extension id is: Autodesk.glTFExtension

    Initialization

    Using the glTF 2.0 Loader, you can load local glTF models in Viewer SDK. Initialize the page using function Autodesk.Viewing.Initializer().

    var viewer;
var options = {
    env: 'AutodeskProduction2',
    api: 'streamingV2',  // for models uploaded to EMEA change this option to 'streamingV2_EU'
    documentId: 'tests/unittest/models/glTF/duck.gltf'
    getAccessToken: function(onTokenReady) {
        var token = 'YOUR_ACCESS_TOKEN';
        var timeInSeconds = 3600; // Use value provided by APS Authentication (OAuth) API
        onTokenReady(token, timeInSeconds);
    }
};

Autodesk.Viewing.Initializer(options, function() {
    var htmlDiv = document.getElementById('forgeViewer');
    viewer = new Autodesk.Viewing.GuiViewer3D(htmlDiv);
    var startedCode = viewer.start();
    if (startedCode > 0) {
        console.error('Failed to create a Viewer: WebGL not supported.');
        return;
    }
});

    Usage

    The glTF 2.0 Loader supports these features:

    • glTF2.0 loading, including geometry and basic material.
    • Basic navigation, including Orbit, Zoom and Pan tool.
    • Basic selection, including mapping dbID to glTF nodes.
    • Show node name on property panel and model browser.
    • Supports only free measurement mode.

    The glTF 2.0 Loader does not support these features: * Property database. * Measurement tool.

    To activate free measurement mode:

    var measuretool = NOP_VIEWER.getExtension('Autodesk.Measure');
measuretool.setFreeMeasureMode(true);
