Lossless compression enabling streaming and visualization of 3d massive data


QUANTIZER is a wavelets-based compression/decompression library implementing a vector quantization. Currently applied to 3D multi resolved models, this
technology allows to generate downstream the relevant level of details in regard to the device resolution.

For each frame, intrinsic partitioned structure allows to decompress the sole region of interest. Implementation of the decompression in GP-GPU dramatically saves upstream resources (network, bus, memory), while enabling ‘out-of-core’ and implicit culling. Beyond visualization, the decompressed 3D meshes can becomputed.


Overwhelming existing solutions based on single rate or even progressive coding.
