Analysing the Influence of Vertex Clustering on PCA-Based Dynamic Mesh Compression

Popis výsledku v původním jazyce

The growth of computational power of contemporary hardware causes technologies working with 3D-data to expand. Examples of the use of this kind of data can be found in geography or gaming industry. 3D-data may not be only static, but also dynamic. One way of animated 3D-data representation is expressing them by "dynamic triangle mesh". This kind of data representation is usually voluminous and needs to be compressed for efficient storage and transmission. In this paper, we are dealing with the influenceof vertex clustering on dynamic mesh compression. The mesh is divided into vertex clusters based on the vertex movement similarity and compressed per-partes to achieve higher compression performance. We use Coddyac as a basic compression algorithm and extend it by adding well known clustering algorithms to demonstrate the efficiency of this approach. We also deal with what clustering is the most appropriate Coddyac.
