Portalgraph

Portalgraph is a technology that turns a projector screen into a VR space that can be viewed from any direction in 3D. Based on the CAVE technology developed in the 90’s and combined with modern state-of-the-art development technology, it provides a comfortable, open, and enjoyable VR experience for those around you, solving the problems that VR headsets have had, such as being heavy and uncomfortable, not being able to do other things, and not being able to see what you are doing from the surroundings. In addition, as an application, we can provide not only CG but also live-action VR experiences, and not only on a wall screen but also on a tabletop or box-shaped pseudo-holograms.

– What can Portalgraph do?

Portalgraph is a technology that allows users to easily experience immersive images as if they were wearing VR goggles with 3D glasses and a VIVE tracker, solving the disadvantages of wearing VR goggles, such as not being able to see what is going on around you, not being able to ensure safety, being heavy, and looking suspicious(?). In addition, Portalgraph can be used not only on a screen, but can also be projected on a desk, a box with multiple displays, or a ceiling, making it suitable for a wide variety of applications. People can also develop and create works using Portalgraph technology, allowing individuals to create and enjoy their own works as a hobby.

– Prize of SOWN at Tokyo Game Show!

Tiny Drive,” a holographic 3D game using Portalgraph technology, won the Grand Prix of the Sense of Wonder Night 2023 (SOWN), the gateway to success for indie game developers at the Tokyo Game Show. The jury commented, “It can be seen as media art while maintaining a sense of nostalgia and it creates a new experience with a new technology called Portalgraph”.

– Distinctive Presence at the INTERBEE IGNITION x DCEXPO Exhibit

At INTERBEE IGNITION x DCEXPO, award-winning works such as “Tiny Drive” were exhibited. It attracted visitors, and there was a long queue to do a demo. The booth also attracted Ms. June Kim, conference chair of SIGGRAPH Asia 2023 (International Conference on Computer Graphics and Interactive Technologies), who was very interested in experiencing the technology. Portalgraph succeeded in promoting their technology widely.
