how to get coordinate information in Viewer?
do you need the coordinates of the component, or some other coordinate information? If it is a component, viewer loads geometric patches, not the design software has the so-called 'location' information.
viewer provides the transformation matrix information of the component, which can be obtained through the following code. If you just want to have a reference point, consider using the center of the box, which is also demonstrated in the following code:
var dbid = 1234;
var bounds = new THREE.Box3();
var box = new THREE.Box3();
var instanceTree = NOP_VIEWER.impl.model.getData().instanceTree;
var fragList = NOP_VIEWER.impl.model.getFragmentList();
instanceTree.enumNodeFragments(dbid, function (fragId) {
console.log('fragId:' + fragId);
//
fragList.getWorldBounds(fragId, box)
//
bounds.union(box);
//
//
//
var fm = new THREE.Matrix4();
fragList.getWorldMatrix(fragId,fm);
console.log('frag matrix:' + JSON.stringify(fm));
