change background color in open3d.visualization.draw_geometries

Question

I want to change the background color in Open3D when I draw geometries using open3d.visualization.draw_geometries, but I can't figure out how to that, as the documentation is not showing how to do it.

can you please tell me how can I change background color please? or show Skymap or example? thanks in advance.

Answer 1

open3d.visualization.draw_geometries is a small wrapper function that calls open3d.visualization.Visualizer class methods. For customizing the rendering options, you will have to move to using Visualizer class directly which allows finer control on rendering and view control options.

Now, to change background color, you can use Visualizer as below:-

import open3d as o3d

ply_point_cloud = o3d.data.PLYPointCloud()
pcd = o3d.io.read_point_cloud(ply_point_cloud.path)

vis = o3d.visualization.Visualizer()
vis.create_window(visible=True)
# Call only after creating visualizer window.
vis.get_render_option().background_color = [0, 0, 1]
vis.add_geometry(pcd)
vis.run()
