可以通过下列方式拿到构件树:
var it = viewer.model.getData().instanceTree;
//或
viewer.getObjectTree(function( instanceTree ) {
console.log( instanceTree );
});
因数据优化的缘故,所有数据都是平坦化过的,要重建数据结构可以通过:
function buildModelTree( model ) {
//builds model tree recursively
function _buildModelTreeRec( node ) {
it.enumNodeChildren( node.dbId, function(childId) {
node.children = node.children || [];
var childNode = {
dbId: childId,
name: it.getNodeName( childId )
};
node.children.push( childNode );
_buildModelTreeRec( childNode );
});
}
//get model instance tree and root component
var it = model.getData().instanceTree;
var rootId = it.getRootId();
var rootNode = {
dbId: rootId,
name: it.getNodeName( rootId )
};
_buildModelTreeRec( rootNode );
return rootNode;
}
var root = buildModelTree( viewer.model );
