[FEATURE] Desktop application support

[state-of-the-art]

Is your feature request related to a problem? Please describe.

Right now Handy 3D Scanner supports only Android (and limited Linux) OS. It will be good to run the same on the other operating systems, like Windows & MacOS.

Describe the solution you'd like

Qt 5 framework and libraries we using (librealsense, draco) - are quite portable and since we already have linux user interfaces (mouse support) - that shouldn't be a big deal to support the other platforms.

Additional context

The only limitation we have right now - is file management. Need to prepare an unified interface to access the filesystem (to open/save/export pointclouds / scene).

Hi, maybe this is not the right place to write about, but i wanted to know if i need to have depth camera to test this application on Linux desktop or is it possible to run this application on Linux and just play around a bit with webcam? I was able to compile the application on ubuntu 20.04 but it seems to crash on launch.

Hi @suvirbhargav , sorry - for now the desktop is not supported oficially.

The main purpose of this app - to capture the pointclouds from stereo cameras (right now it's intel D400 series) - means your webcam will not work. But you still can run the app to open pcd files in the edit tab.

Seems you are trying to run the app from docker - most probably it have no connection to your X server on the host system - that's why you see this issue.
