I'm using Open3D to visualize 3D point clouds I'm working on. For this purpose I'm using open3d.visualization.Visualizer. Works good. Now I'm wish to embed this window into a larger GUI, where I'd show two Visualizer windows and some text label below them. Basically, it would be a simple design with two Visualizer objects next to each other, and text displayed below them. The GUI module from the same lib is here. I can't seem to figure out from documentation if this is possible? Is there maybe some other framework that would enable me to do this?
