+# VU virtual lab
+This is a template for creating a virtual lab environment using 360º panoramic images and the open source panorama viewer [Pannellum](https://pannellum.org).
+## Image capture and pre-processing
+The 360º panoramic images are expected to be in [equirectangular](https://en.wikipedia.org/wiki/Equirectangular_projection) format. Below an equirectangular image taken using the Insta360 X3 camera in the 72MP mode is shown.

+
+First, the image should be as an equirectangular image using the software provided with the camera (in this case Insta360 Studio).

+
+The resulting image is likely large (~30-40 MB), so compression is necessary. This can be done using any image editing software (in this case Pixelmator Pro). The quality is set to 80% and the WebP format is used, as this is most space-efficient.
