My Question

Hi,

I am currently trying to position the camera of the Visualizer at a specific point, but every value I set up will be ignored and the visualizer always displays the same view of my mesh.

This is my code so far:

vis = o3d.visualization.Visualizer()

vis.create_window()
vis.add_geometry(pcb_mesh)

option: o3d.visualization.RenderOption = vis.get_render_option()
option.show_coordinate_frame = True
option.mesh_show_back_face = True
option.light_on = False

view_control: o3d.visualization.ViewControl = vis.get_view_control()
view_control.set_front([ -0.16369650945088704, 0.0082033463888920785, -0.98647663829490639 ])
view_control.set_lookat([ -0.5126953125, 0.0146484375, 1.3552540928219587 ])
view_control.set_up([ -0.14927274718300235, 0.98824562139584249, 0.032988463746963764 ])
view_control.set_zoom(0.7)

vis.update_geometry(pcb_mesh)
vis.poll_events()
vis.update_renderer()

image = vis.capture_screen_float_buffer()
vis.destroy_window()

I also tried

cam = view_control.convert_to_pinhole_camera_parameters()
cam.extrinsic = ...
cam = view_control.convert_from_pinhole_camera_parameters(cam)

But this also has no effect.

I am using Open3D v0.17.0, but I also tried downgrading to 0.16 and 0.15.

Am I missing something here?

Thanks. This is a known bug (#6009) in the 0.17.0 release, for which a fix was recently proposed (#6116).
