THE BACKGROUND INFORMATION IN ADVANCING-FRONT METHOD FOR THE TRIANGLE MESHING

A method is presented to give the background information in Advancing-Front Method for triangle meshing．The potential induced by electric charges is used as the background information．The potential induced by some electric charges is limited in some certain direction for adding grids at special area．Compared with the conventional background grid approach，the presented method is simpler，with less manual work，and the information is more continuous．
