New VR projector technology that does not block the view

Portalgraph is a novel VR projector technology that projects VR spaces onto screens, opening a portal that connects 'here' with alternate spaces.


Portalgraph for live-action content

Portalgraph is also ideal for displaying live-action content using 360° cameras. Portalgraph can display spaces with depth that cannot be expressed with domed screens.


Even a small screen becomes another space.

Portalgraph on a large screen is fun, but Portalgraph makes it easy to create a different space on a small screen as well.


For Unity Support

Portalgraph-enabled apps can be developed in Unity, which is easy to learn. Simply drag and drop assets into your scene.

Easy to install

All you need is a commercially available 3D projector (we recommend an ultra-short-throw projector), 3D glasses, VIVE tracker, VIVE base station and a PC. Once our software is incorporated, the screen immediately becomes a VR space.


The system also supports 3D with red and blue glasses, so you can also experience it with a regular projector or large monitor that is not 3D.
