Which one is the example for real-time 3D reconstruction example like youtube?

### My Question

I found a real-time 3D reconstruction example in one video on youtube like [https://youtu.be/pLCVCH7ypI4](url).
If I can create an indoor environment as a mesh, especially with real-time 3D reconstruction techniques, that is exactly the solution that I want to have. It would be appreciated if someone could introduce the process of configuring this with open3d.

Also, dense_slam_gui.py makes ab error like below in my computer.

Config file was not provided, falling back to default dataset.
Traceback (most recent call last):
File "c:\Open3D\examples\python\t_reconstruction_system\dense_slam_gui.py", line 476, in
config = get_default_dataset(config)
File "c:\Open3D\examples\python\t_reconstruction_system\common.py", line 99, in get_default_dataset
config = lounge_dataloader(config)
File "c:\Open3D\examples\python\t_reconstruction_system\common.py", line 65, in lounge_dataloader
lounge_rgbd = o3d.data.LoungeRGBDImages()
AttributeError: module 'open3d.cpu.pybind.data' has no attribute 'LoungeRGBDImages'

It would be appreciated as well if someone explain the reason for the error and the solution how it works.

Thanks!
