METHOD FOR TERRAIN RENDERING USING BIASED VERTEX DISTRIBUTION

摘要

PURPOSE: A topography rendering method using location of a deflection map is provided to efficiently reduce a geometric error by distributing a geometric error. CONSTITUTION: A complex value of a sampling point is calculated by analysis of original DEM(Digital Elevation Model) data(201). The complex value is stored in a complex map(202). A motion vector is calculated with reference to the complex map(203). The motion vector is stored in a concentration map(204). An elastic force is calculated about the motion vector(205). The motion vector is stored in a bias map(206).
