you can get the component tree in the following ways:
var it = viewer.model.getData().instanceTree;
//
viewer.getObjectTree(function( instanceTree ) {
console.log( instanceTree );
});due to data optimization, all data are flattened. To reconstruct the data structure, you can use:
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 );when using three.js, use raycaster to select objects. If there is div occlusion on the upper layer of the canvas, the mouse can still select the model in the canvas. If you want to select a model that is not available when there is div occlusion, how to ...
