Abstract

Systems and methods usable to provide synthetic environments for computer generated forces include supplemental identifying information applicable to the respective surface. Polygons used to represent the surface can be overlayed with supplemental information to provide a higher fidelity environment in which to mobilize the computer generated forces.

Claims

1. A system comprising:

a computer work station coupled to at least one visual display;

a plurality of data bases stored on a computer readable medium coupled to the workstation, the data bases include visual out the window display data, infrared and radar display data and computer generated forces data including coded surface material specifying data and a representation of a selected stored environment;

and computer generated mobilizing software, executable by the work station to combine the coded surface material specifying data with the stored environment and to visually display mobility of computer forces on the visual display.

2. A system as in claim 1 where the stored environment is represented by a plurality of polygons, and where the mobilizing software selects a current polygon from the database, determines if a surface material data flag has been set and if so accesses respective data and combines it with the current polygon'"'"'s surface data prior to visually displaying mobility of computer generated forces.

3. A system as in claim 2 where the surface material is selected from a class which includes at least water, dirt, trees and grass.

4. A system as in claim 3 which includes additional software executable by the computer work station to create and store on the computer readable medium the coded surface material specifying data.

5. A system as in claim 4 where the coded surface material specifying data comprises a plurality of data elements, stored on the computer readable medium with each of the elements associated with a respective polygon and with the elements specifying at least one of the water, dirt, trees, or grass.

6. A system as in claim 5 where at least some of the elements specifying a second material selected from the class.

7. A system comprising:

at least one computer coupled to at least one visual display, and a computer readable data storage device which includes information defining a prestored, multi-regional representation of an environment, prestored lineal information and surface material specifying information associated with at least some regions of the environment;

the computer executes software which retrieves information relative to, a selected region of the environment, determines if additional, non-lineal, surface material information is available for that region from the data storage device and, if so, combines information as to surface characteristics of that region with the additional surface material information and displays a regional composite of the combined surface characteristic information and additional surface material information on the visual display.

8. A system as in claim 7 where the storage device includes visual out the window data also presentable on the display.

9. A system as in claim 8 which includes additional software, executable by the computer, to move computer generated forces with respect to the regional composite and present such forces and the regional composite on the display.

10. A system as in claim 7 which includes additional software, executable by the computer to create and save on the storage device a plurality of surface material specifying information elements, each associated with a region of the representation of the environment.

11. A system as in claim 10 where at least some of the information elements specify a surface material selected from a class which includes at least water, dirt, trees and grass.

12. A system as in claim 11 where at least some the elements specify a material height corresponding to a surface feature elevation.
