The softare loads single layer DEM with image drape (usually drone acquired) and would need to be adapted to deal with multi-images. We did want to try and deal with multiple images and be able to switch between them overlayed on the DEM. The VR experience allowed walking and flying (drone like) plus mapping capabilities (point,line polygon) and export to GIS.
It uses high spec laptops/Pcs with oculus headsets but we had some prototypes that ran on mormal computers – onscreen without VR headsets using keyboard controls. Yes we used unity.
I dont have a project of my own but happy to be involved on another project if I can be of help.

We have developed VR for fieldwork with drone data with SFM and imagery/DEM and have developed some workflows and software: see http://www.3dtelc.com. It was an Erasmus+ funded project: https://ec.europa.eu/programmes/erasmus-plus/projects/eplus-project-details/#project/2017-1-UK01-KA203-036719
