摘要： Provided are an apparatus and a method for representing a multi-level LOD three-dimensional image. The present invention configures a multi-level LOD hierarchical mesh for each hierarchical level with a different LOD level by arranging triangular patches of a upper hierarchical level(lower resolution) to have approximately k×k of triangular patches of an lower hierarchical level (higher resolution) and samples information on height of a target image to allocate the sampled height information to each vertex of the triangular patches included in the multi-level LOD hierarchical mesh, determines an LOD of each triangular patch according to a view point of a virtual camera, and connects the adjacent triangular patches without gaps when adjacent triangular patches among the triangular patches of the multi-level LOD hierarchical mesh have different LOD levels.
