Tokyo, Feb 24 (PTI) Scientists have developed a new technology that creates 3D images by using a laser to form tiny bubbles inside a liquid screen, allowing users to view images in a columnar display from all angles without any special glasses or headsets.

“Creating a full-colour updatable volumetric display is challenging because many three-dimensional pixels, or voxels, with different colours have to be formed to make volumetric graphics,” said Kota Kumagai, from Utsunomiya University in Japan.
