A method for rendering a real-time conformal view of terrestrial body's terrain being traversed by a mobile platform includes storing digital terrain elevation data (DTED) tiles for at least a portion of the terrain of a terrestrial body into an external removable mass data storage device (ERMDSD). The ERMDSD is connectable to an onboard computer system (OCS) comprising embedded mobile platform components that include at least one processing card, at least random access memory (RAM) device and at least one graphics card. The method additionally includes executing a real-time rendering assist application (RTRAA) stored in the processing card to dynamically repackage the DTED tiles into DTED chunks being representative of an area of the terrestrial body to be traversed (ATBT) by the mobile platform. The method further includes executing the RTRAA to create a base mesh of root diamonds representative of the ATBT and tessellate the root diamonds to create a plurality of leaf diamonds. Further yet the method includes utilizing the graphics card only to render the leaf diamonds, thereby generating a real-time conformal view of the ATBT.
