My Question

Hello,

I am trying to convert mesh (.stl) object to point cloud.

     extrinsic = np.array(T_wc)
      camera_params = o3d.camera.PinholeCameraParameters()
      camera_params.intrinsic = params.intrinsic
      camera_params.extrinsic = extrinsic

      # Apply the updated camera parameters to the visualizer
      ctr.convert_from_pinhole_camera_parameters(camera_params,True)
      vis.poll_events()
      vis.update_renderer()

      # Capture the point cloud from the camera's perspective
      vis.capture_depth_point_cloud(pcd_temp_path,True,False)

This is the result I am getting

The point cloud is very sparse, I would like to get a more dense point cloud.

For reasons I cannot mention, I cannot use the Ray_casting function from open3d.

What is the way to improve the density of my point cloud using capture_depth_point_cloud or any other post processing methods?
