Currently, these reviews have to be carried out across several different platforms, while the application we developed integrates multiple tools (i.e. an interactive 3D environment, a video-conferencing feed, and a chat) in one coherent interface that can also be connected to popular DCCs, like Maya, in order to create a quick, accessible, and expressive way to discuss and review 3D models of any nature for any user, regardless of their own technical background and level of familiarity with modelling software.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Synchronous Editors; Document management; Network servicesCCS ConceptsHuman-centered computingSynchronous EditorsDocument managementNetwork servicesKollani: A Distributed Tool for Real-Time Collaborative Reviews of 3D Assets10.2312/egp.202610012 pages
