80 results about "Volumetric display" patented technology

A volumetric display device is a graphic display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space.

The invention relates to the field of three-dimensional technology and provides an overground and underground integrated modeling method based on true 3D volumetric display technique. The modeling method comprises following steps of A: using a Bigemap map interception device to intercept a remote sensing bottom diagram in a designed area on a map downloaded from a Bigemap; B: matching a daogle bottom diagram with an underground pipe network CAD measurement graph and using a MAPGIS to draw an underground pipe network vector diagram of the designated area; C: using the MAPGIS and a 3DMAX to perform three-dimensional modeling for overground facilities and underground pipe networks in the designated area; D: performing three-dimensional model integration on a GIS model and a 3DMAX model on a MAPGIS platform; and E: performing space analysis and attribute searching on the integrated three-dimensional models. The modeling method is characterized and advantaged by simple structure, easy operation, low manufacturing cost and fine and smooth models, can be widely applicable for overground and underground integrated modeling in schools, communities, industrial zones and parks, and has high market promotion and application value.
