Abstract:
1. A progressive mesh decoding method comprising: progressively reconstructing at a hardware-based resolution increasing unit a first desired resolution mesh having a first desired resolution level from a base mesh through vertex addition; recording vertex level information indicating a resolution level of the first desired resolution mesh at a hardware-based vertex level information recording unit for the vertices added; and in response to a second desired resolution mesh having a second desired resolution level lower than the first desired resolution level being requested, progressively reconstructing at a hardware-based resolution decreasing unit the second desired resolution mesh by vertex deletion, vertices to be deleted being determined at a hardware-based deletable-vertex searching unit based on the vertex level information, wherein the vertex addition comprises adding vertices to the base mesh and excluding adding two or more vertices by splitting a vertex, and wherein the vertex deletion comprises deleting vertices from first desired resolution mesh and excluding deleting a vertex by merging two vertices to form a vertex.
