Abstract: A progressive mesh decoding apparatus, a progressive mesh decoding method and a computer readable recording medium using the same are provided. In the progressive mesh decoding method, a first desired resolution mesh is progressively reconstructed from a base mesh through vertex addition. Vertex level information indicating a resolution level of a mesh corresponding to a predetermined process of the first desired resolution mesh reconstructing process is recorded for respective vertices added at the predetermined process. In response to a second desired resolution mesh having a second desired resolution level lower than the first desired resolution level being requested, the second desired resolution mesh is reconstructed by deleting vertices from the first desired resolution mesh, wherein vertices to be deleted in a predetermined process of the second desired resolution mesh reconstructing process are determined based on the vertex level information.
