POMAR: Compression of progressive oriented meshes accessible randomly

This paper presents a new random accessible and progressive lossless manifold triangle mesh compression algorithm named POMAR. It allows to extract different parts of the input mesh at different levels of detail during the decompression. A smooth transition without artefacts is generated between adjacent regions decompressed at different levels of detail. Our approach allows selective decompression with low delay and compares favourably to previous random accessible and progressive schemes in terms of compression rates. [Display omitted] •We present a new progressive random accessible mesh compression scheme.•No post-processing is required after the decompression to stitch adjacent clusters.•A smooth and high quality transition is generated between clusters.•It compares favourably to previous schemes in terms of compression rates.
