VR & immersive 3D

From Kunohe Castle VR and ILC visualization to the SpheriCul spherical display. Below are four moving demonstrations from the original SpheriCul website.

360° MovieHigh-resolution panoramic imagery and globe data viewed from any direction.
VolumetricVolumetric figures and their motions viewed from different angles.
AquariumA moving aquarium world presented inside the spherical display.
3D InteractionGesture-based manipulation of three-dimensional objects and scenes.

These are the original SpheriCul animations. Press play to watch each demonstration.
