The decompression works by applying the aforementioned steps in inverse order. Smoothing over the voxels' centers is applied afterwards in order to reconstruct the input 3D points. Optionally 3D mesh is reconstructed over the approximate point cloud in order to obtain the original geometric object. The quality of the compression/decompression is controlled by resolution of the 3D voxel grid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for near-lossless compression and decompression of 3D meshes and point clouds","description":"Fast near-lossless compression includes four steps: voxelization of the 3D geometry, decomposing the 3D voxel space into consecutive slices, encoding each slice with chain codes, and compressing the c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9734595","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
