Independent implementations
Bitruvius codecs (the Turbo family, RIPT, and BVC) are independent, clean-room implementations. Where a Bitruvius codec reads or writes a third-party format, it implements the openly published format specification; it does not contain, copy, or derive from the third party's source code. Wire-format compatibility claims (for example "byte-identical output") describe interoperability with the published format, verified by our test suites.
Open-source attributions
The live demos on this site compare Bitruvius codecs against the official reference implementations, running unmodified in your browser. We gratefully acknowledge:
Reference raster codec compared by TurboLERC.
Reference point-cloud codec compared by TurboLEPCC. A compiled WebAssembly build is redistributed for the live benchmark — license copy. View license & provenance ↗
Reference Gaussian-splat codec compared by TurboSPZ. A compiled WebAssembly build and the sample capture scenes are redistributed for the live benchmark — license copy. View license & provenance ↗
Reference Gaussian-splat codec compared by BVC and TurboSPZ. A decode-only WebAssembly build (compiled, unmodified) is redistributed for the live benchmark — license copy. View license & provenance ↗
Reference WebP codec compared by TurboWebP.
Reference JPEG XL (ISO/IEC 18181) codec compared by TurboJXL.
Reference codec compared by TurboZstd. Frame format specified in RFC 8878.
Reference codec compared by TurboLZ4.
Reference LZW codec compared by TurboLZW. The LZW patents expired in 2003–2004.
LAZ/COPC decoder used as a comparison lane in the point-cloud demo (loaded from a public CDN).
LAS/COPC parsing used by the point-cloud demo (loaded from a public CDN).
Mesh/point-cloud decoder used as a comparison lane in the point-cloud demo (loaded from a public CDN).
WebAssembly builds of the reference image codecs used as comparison lanes (loaded from a public CDN).

Dataset credits
The point-cloud demos use the Autzen Stadium LiDAR scan (Eugene, Oregon) — a classic openly distributed benchmark dataset popularized by the PDAL project. The Gaussian-splat demos use the horned lizard and raccoon family sample captures from Niantic's open-source libspz repository (MIT License). Satellite basemap imagery in the demos is © Esri, Maxar, Earthstar Geographics, attributed in the map view as required.
Benchmark methodology
Performance comparisons on this site — including the live in-browser demos — reflect our own measurements of unmodified reference implementations and Bitruvius codecs processing identical input bytes, with warm-up passes so all codecs are measured at steady state, on the stated hardware or in your own browser. Methodology details accompany each chart. Results vary by workload, hardware, and configuration. Reference implementations are used under their respective open-source licenses; their inclusion is not an endorsement by their publishers.
