Abstract

A device for displaying information reducible to three spatial parameters such as three-dimensional mathematical formulae, three-dimensional maps, and the spatial distributions of vehicles moving in three-dimensional space includes a plurality of transparent plastic sheets arranged in a spaced, parallel array. Each of the transparent sheets is marked with a coordinate grid rectangular, polar, logarithmic, or other and is spaced from adjacent sheets in a regular pattern linear, logarithmic, or other. The coordinate points defining the information to be displayed are marked on each sheet, so that viewing the complete assembly provides a three-dimensional plot of the information viewable from any angle and in true scale. In an alternate form of the invention, the coordinate grids of each of the transparent sheets are defined by electrical conductors with a light-emitting structure, incandescent or luminescent, at the grid intersections whereby a display may be energized by passing current through the information-defining intercepts.

Claims

1. A device for providing a data display in a three-dimensional configuration, comprising:

a cubical frame including four vertical posts, a base frame, and a top frame similar to said base frame;

a substantial plurality of transparent planar data sheets in stacked array, each of the sheets having respective selectively positioned visible datum elements thereon; and

a plurality of support separators mounted in spaced relation on said posts and within said cubical frame to receive and support respective ones of the transparent planar data sheets in an array stacked one above the other;

whereby said respective datum elements on the respective data sheets cooperate to define a data display in a three-dimensional configuration.

2. The cubical frame defined in claim 1 wherein said support separators comprise wires extending between diagonally opposed posts to receive and support said planar data sheets.

3. The cubical frame defined in claim 1 wherein said support separators are equispaced.

4. The cubical frame defined in claim 1 wherein said support separators constitute slots in said vertical support members to receive said planar data sheets.

5. The three-dimensional data display defined in claim 1 wherein the spacing of said spaced separators is non-linear in accordance with a mathematical relationship.

6. The three dimensional data display defined in claim 1 wherein said transparent data sheets include a grid of predetermined dimensions on each.

8. A device for providing a three-dimensional data display, according to claim 1, wherein:

the respective stacked data sheets are in such spaced relation that the datum elements on respective sheets are accessible for physical measurements of the data or configuration displayed.

7. A device for providing a data display in a three-dimensional configuration, comprising:

a cubical frame forming a right parallelepiped;

a substantial plurality of transparent planar data sheets in stacked array, each of the sheets having respective selectively positioned visible datum elements thereon; and

whereby said respective datum elements on the respective data sheets cooperate to define a data display in a three-dimensional configuration.

9. A device for providing a data display in a three-dimensional configuration, comprising:

a cubical frame forming a right parallelepiped,

a substantial plurality of transparent planar data sheets in stacked array,

whereby said respective datum elements on the respective data sheets cooperate to define a data display in a three-dimensional configuration,

a first substantial plurality of electrical conductors on each of said data sheets and extending thereacross in a first direction,

a second substantial plurality of electrical conductors extending across each said data sheet in a second direction so that said first conductors intersect said second conductors,

an illuminable indicia means interconnected at each respective intersection between a respective one of said first conductors and a respective one of said second conductors, and

electrical signal means for selectively energizing selected ones of said first conductors and selected ones of said second conductors on each data sheet to illuminate selected ones of the illuminable indicia means to define visible selectively positioned datum elements on the respective data sheets to cooperate to define an illuminated data display in three-dimensions.

10. A device for providing a three-dimensional data display, according to claim 9, wherein:

the respective stacked data sheets are in such spaced relation that the datum elements on respective sheets are accessible for physical measurements of the data or configuration displayed.
