Saving output of draw_geometries as image file without opening a window

[n-campbell]

I'm currently using the method below to save the output of draw_geometries as in a .png file for later use in WandB. Since I have this implementation in a training loop, it is inconvenient for the visualization window to continuously pop up. Would it be possible to achieve the same resulting image without having a pop up window?

vis = o3d.visualization.Visualizer() vis.create_window() vis.add_geometry(pcd) vis.update_geometry(pcd) vis.poll_events() vis.update_renderer() vis.capture_screen_image(path) vis.destroy_window()

Hi @n-campbell, Does replacing create_window() with create_window(visible=False) solve your issue?

Hi, it has been one year, has anyone solved this issue?

In my case the program just becomes silent, no window, and no image is saved.

In my case, I need to save more than 1000 images in a script, and my work around is to put my iphone on the ESC keys so it kills the windows as soon as it pops up. I do wish to find a simpler way.

visible=True works on my Ubuntu 20.04. True or False seemingly depends on your system.
