Browser Based 3D for the Built Environment

Abstract

Digital 3D models have become a central tool for geo-information. For many participatory and collaborative applications, distributing these models easily is essential. Several technical solutions exist for creating online systems that facilitate the study of 3D models in the context of the built environment. First, we provide an overview on browser based interactive 3D visualizations through presenting a set of existing systems applied in Finland, and discussing their common properties and differences. Second, we experiment with an online 3D application development platform in order to obtain first-hand experience. The systems studied show a high potential for browser based 3D applications: interactive visualizations with multi-user characteristics and dynamic elements can be built by leveraging the 3D web technologies. Finally, we suggest a list of essential capabilities for online 3D visualization, covering the spectrum of possibilities available in modern web-based 3D.
