My company (www.igloovision.com) has just developed a Unreal camera rig that sends a 360º fov back to our 360 projection domes and cylinders. The camera is now a plug-in and can be dropped into most scenes Igloo Vision - 360º Unreal Engine on Vimeo it can also output stereoscopic 3D
We are looking for unreal users that have well developed, quality scenes that might want to see their work in 360. This could be games or visualisations. We demo to creative agencies, corporates, architectural firms etc on a daily basis so if you would like to get your work in front of lots of people let me know and we can discuss a collaboration.
