Abstract
This invention relates generally to new and improved methods and apparatus for displaying volumetric 3D images with colors and for barrier-free interaction with the 3D images. A raw 3D dataset is first processed into a viewable data with a geometry description in the form of a collection of scattered points, curves and surfaces, and a corresponding color description. One of the four color combination methods, exact, spatial, temporal, or spatio-temporal, is the used to process the viewable data into three data subsets, each of a collection of points and of a different color frequency. A set of separate image patterns, each pattern of a different color frequency, is then displayed on a color display system according to the content of the three data subsets. In the final step, the set of separate image patterns is recombined and displayed on a volumetric display device to form color volumetric 3D images.
