Despite recent advances, especially in web-based Collaborative Virtual Environments (CVEs) using real-time 3D content, Web technology still requires an efficient way to distribute and stream large-scale 3D data. In this paper, we present 3DEvent: an event-driven framework to collaboratively manipulate predesigned 3D content in real-time on a web-based platform. This work introduces a new approach in achieving 3D object manipulation tasks during collaborative design stages using event-sourcing. Usually, a client-server architecture supports updates to the 3D environment state. Peer-to-peer (P2P) allows direct communication between teammates reducing response times during collaboration and decreasing server load, reducing the costs of providers. 3DEvent enables P2P-assisted delivery of 3D dynamic content in a web browser via WebRTC. By combining concepts from distributed event-processing and mesh-processing, 3D independent rendering and event-based synchronization, we present 3DEvent framework and potential uses associated that support history-aware 3D applications into a unified distributed processing solution for 3D web-based CVEs.
