METHOD FOR DEVELOPING A BROWSER-BASED VIRTUAL MUSEUM EXHIBITION SYSTEM BASED ON WEBVR TECHNOLOGIES

The paper proposes a method for developing a browser-based virtual museum exhibition that presents objects immersively without installing any application. The method relies on the WebXR Device API, the successor of WebVR, the A-Frame library and the glTF 2.0 format, and combines multi-stage optimization of photogrammetric models (decimation, Draco and KTX2 compression) with zone-based progressive loading. An analytical evaluation on a 12-object scenario based on the collection of the I.V. Savitsky State Museum of Arts of Karakalpakstan shows that the method reduces content size by 95.9 % and GPU texture memory by 97.7 %, and shortens the transfer time before entering the exhibition to 4.2 s on a 10 Mbit/s network.
