My Question

I was just wondering if there is a way to have multiple visualization window at once for class o3d.visualization.VisualizerWithEditing. I am trying to implement manual registration by picking point (correspondences) between two point cloud. Since I have not found a way to refer back to where the points were picked in source point cloud such that corresponding points could be picked in target point cloud. I thought it would be easier if two point cloud window were side by side for ease.

I went through open3d.visualization.gui and multi_window.py, but was unable to pick point in those visualization. Thank you in advance.
