Independent implementations

Bitruvius codecs (the Turbo family, RIPT, and BVC) are independent implementations. Where a Bitruvius codec reads or writes a third-party format, it targets that published format and its documented behavior. Wire-format compatibility claims (for example "byte-identical output") describe interoperability with the published format, verified by our test suites. Third-party software we incorporate or redistribute is acknowledged below under its own license.

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:

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.
