Abstract: There are provided a method of generating a terrain model and a device using the same. The method of generating a terrain model includes dividing a primitive terrain model into a plurality of partial terrain sections based on a predetermined criterion, assigning the plurality of partial terrain sections to a multiprocessor, and generating a final terrain model by performing a terrain transformation simulation of the plurality of partial terrain sections through parallel processing based on the multiprocessor. Therefore, it is possible to rapidly generate a realistic terrain model.

Abstract: The present disclosure relates to a method of editing terrain data created by a procedure method, and particularly to a method of editing terrain data based on multiresolution for intuitively editing high-quality terrain data. To this end, the method of editing terrain data created by a procedure method includes: inputting terrain data in a form of a height map; processing a multiresolution analysis by dividing the input height map for each band; processing a terrain edition based on the multiresolution by adjusting a height value within a predetermined distance from a position selected from the multiresolution analyzed height map; and storing the multiresolution-based terrain edition processed height map in a form of a progressive mesh.
