Colour volumetric display based on holographic-laser-excited graphics using drawing space separation
Abstract A volumetric display generates a graphics that can be viewed from 360 $$^{\circ }$$ ∘ by representing the 3D information of an object as voxels in physical space. However, the natural properties of physical objects, such as 3D information and colors, and the seamless relationships between g...
