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.
As a result Wipe will, likewise, struggle in such cases.
You will find that a higher 'Locality' value with all else equal, will yield an image with areas of starker contrast.
The Wipe module is able to detect horizontal or vertical banding and correct for this.
Signal bias is a fixed background levels which, contrary to a gradient, affects the whole image evenly.
You can convert everything you see to a format you find convenient. Give it a try!
