The 'WebVR' button in the module exports your image as a standalone HTML file. This file can be viewed locally in your webbrowser, or it can be hosted online.
It renders your image as an immersive VR experience, with a large screen wrapping around the viewer. The VR experience can be viewed in most popular headsets, including HTC Vive, Oculus, Windows Mixed Reality, GearVR, Google Day Dream and even sub-$5 Google Cardboard devices.
To view an experience, put it in an accessible location (locally or online) and launch it from a WebVR/XR capable browser.
Please note that landscape images tend to be more immersive.
Nevertheless the result can look quite pleasing when simply browsing past the image in a Facebook feed.
The Entropy module is very flexible in its image presentation.
The Shrink module allows you to modify the appearance of stars in your image.
Once all issues are fixed, launch AutoDev again and tell it to 'redo' the stretch.
You can convert everything you see to a format you find convenient. Give it a try!
