The transmission of such an animation is a task that consumes large amounts of bandwidth, as the position of each particle, in each time instant, needs to be transmitted. We propose a wavelet based compression and streaming mechanism that allows the minimization of the size of the animation data, hence decreasing the total transmission time. The proposed transmission scheme, based on the timelocalized feature of the wavelet transform, will be able to stream the animation so that a receiver can immediately view the fraction of the animation received, while wavelet coefficients are still arriving.Attribution 4.0 International LicenseGeometric compression, streaming, deformable models, wavelet transformGeometric compressionstreamingdeformable modelswavelet transform10.2312/pt.20011321107-1148 pages
