Abstract:
In a computer system having (i) a digital processor, (ii) working memory and (iii) input/output units including input means and a display monitor, a terrain model rapid generation system, comprising:an intermediate data file holding indications/representations of elevation vertices;an extractor and formatter responsive to user input and loosely coupled to the intermediate data file for extracting a subset of vertices from the intermediate data file, combining these vertices into an array and formatting said array into an output specification for a three-dimensional geometric configuration, said specification supporting display of a three-dimensional world model including geographic terrain details; anda user interface coupled to the extractor and formatter for enabling user input of instructions through the input means, said instructions directing the extractor and formatter;wherein the digital processor executes the extractor and formatter and user interface in the working memory to generate and display the three-dimensional world model through the display monitor for user viewing.
