Researchers demonstrate 3D volumetric images

To form threedimensional (3D) images on twodimensional (2D) displays, manufacturers must use electronic or optical tricks to create the 3D illusion. In volumetric displays, however, image points are physically formed in all three spatial dimensions. Consequently, a 2D pixel becomes a voxel (volumepixel) with x, y, and ¥coordinates. At the recent International Display Research Conference held in October in Monterey, CA, researchers from Stanford University (Stanford, CA) described a novel 3D
