在聚合查看器中使用 Viewer3D 方法

Question

I want to build functionality for selected objects and shown models in my Aggregated View. I can't seem to figure out how to use the "getSelection" method that is available to the Viewer3D (which Aggregated View is built on?). I can getModel easy enough though:

function extGetModels() {
var modelurn = [];
var visibleModels = viewer.getVisibleNodes();
visibleModels.forEach(model => {
    var i = viewer.getModel(model);
    modelurn.push(i);
});

Is there any examples how I can use the methods in Viewer3D in my aggregated view?

(sorry if this question seems banal, I'm quite new to JS)

Answer 1

It's quite straightforward, just use AggregatedView.viewer . For example,

const view = new Autodesk.Viewing.AggregatedView();
view.init( viewerDiv, options3d );


// somewhere in your code ...

const viewer = view.viewer;
viewer.getVisibleNodes();
