1. An apparatus for reducing popping artifacts for multi-level level-of-detail terrain images, comprising:

  • a terrain patch constructor for forming terrain patches from multi-level level-of-detail patches;

    a level-of-detail deciding unit for receiving the generated terrain patches from the terrain patch constructor and deciding a level-of-detail for each of the received terrain patches according to the camera distance;

    a controller for determining whether adjacent terrain patches exist or not; and

    a tapering unit for receiving terrain patches with neighboring patches of adjacent level-of-detail from the level-of-detail deciding unit in response to the control of the controller and smoothly connects two terrain patches by applying a tapering technique.
