Patent ID: 7612775

Claim:
A method for rendering a real-time conformal view of terrestrial body's terrain being traversed by an airborne mobile platform, said method comprising: determining an area of a terrestrial body to be traversed (ATBT) by a mobile platform; tessellating digital terrain elevation data (DTED) representative of a terrain of the ATBT using a processing card communicatively connected to an independent and separate graphics card, the processing card and the graphics card being embedded components of an onboard computer system (OCS) of the mobile platform; said tessellating DTED further comprising tessellating all of the available DTED pertaining to said ATBT; rendering the tessellated DTED separately from the tessellating of the DTED using the graphics card, on the display in the mobile platform being viewed by an operator of the mobile platform, the rendering on the display being a one-to-one correspondence with what the operator would see from out a window of the airborne mobile platform; and re-tessellating the DTED at a rate of substantially 60 times per second, and updating the rendering at a rate of substantially 60 frames per second such that said re-tessellating provides a continuous, real-time conformal view of the ATBT terrain, and such that there is substantially a one-to-one correspondence between what an operator of the mobile platform would see as the mobile platform traverses the ATBT and what the rendering illustrates.
