使用Autodesk Large Model Viewer查看从ACC创建的点云的ReCap文件。

代码示例：

var lmvDocumentId;

function viewPointCloud (reCapFileUrl) { Autodesk.Viewing.Initializer({ env: 'AutodeskProduction' }, () => { const options = { env: 'AutodeskProduction', accessToken: '', api: 'derivativeV2' }; const documentId = 'urn:' + btoa(reCapFileUrl);

Autodesk.Viewing.Document.load(documentId, (doc) => {
  const rootItem = doc.getRootItem();
  const geometryItems = Autodesk.Viewing.Document.getSubItemsWithProperties(rootItem, {
    'type': 'geometry',
    'role': '3d'
  }, true);
  if (geometryItems.length === 0) {
    console.error('No 3D geometry found in file');
    return;
  }
  
  lmvDocumentId = doc.getDocumentNode().getDocumentId();
  
  const viewerDiv = document.getElementById('viewer');
  const viewer = new Autodesk.Viewing.Private.GuiViewer3D(viewerDiv);
  viewer.start();
  
  const modelUrl = doc.getViewablePath(geometryItems[0]);
  Autodesk.Viewing.Document.load(modelUrl, (modelDoc) => {
    const viewables = modelDoc.getRoot().search({
      'type': 'geometry',
      'role': '3d'
    });
    viewer.loadDocumentNode(modelDoc, viewables[0], {
      keepCurrentModels: true
    });
  }, (err) => {
    console.error('Error loading model');
    console.error(err);
  });
  
}, (err) => {
  console.error('Error loading ReCap file');
  console.error(err);
});

}); }
