Applying transformation matrix to 'extrinsic' in pinhole cameara

I have a mesh object and perspective camera parameters. Based on such information, I'd like to render the output in Open3D

(assuming...
`vis = o3d.visualization.Visualizer()`
`ctr = vis.get_view_control()` )

As of now, I can update the camera transformation matrix via `ctr.convert_from_pinhole_camera_parameters(instance)`
by changing the `instance.extrinsic` matrix of an instance from`instance = ctr.convert_to_pinhole_camera_parameters()`

However, when I replace it from the original one, it always does not show the mesh. Could you let me know how I can apply the current transformation matrix correctly?
