Below is an example in Open3D, in which I created a bunny mesh, as well as a circle mesh. Now I want to create a new window when I click on the circle mesh. Does anyone know how to do that ? Thank you very much.

import numpy as np
import open3d as o3d

def main():
    mesh = o3d.io.read_triangle_mesh(o3d.data.BunnyMesh().path)
    pcd1 = mesh.sample_points_poisson_disk(10000)

    visualizer = o3d.visualization.Visualizer()
    visualizer.create_window()

    visualizer.add_geometry(pcd1)

    # mesh = convert_image_to_mesh(img)
    # mesh.scale(scale=0.1, center=pcd1.get_center())
    # visualizer.add_geometry(mesh)

    # Show xyz axes
    rendering_options = visualizer.get_render_option()
    rendering_options.show_coordinate_frame = True
    rendering_options.background_color = np.asarray([0.5, 0.5, 0.5])

    mesh = o3d.geometry.TriangleMesh.create_sphere(radius=0.1)
    mesh.scale(scale=0.3, center=mesh.get_center())

    visualizer.add_geometry(mesh)

    visualizer.run()

if __name__ == "__main__":
    main()
