Abstract

Digital 3D geometric 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. To provide an overview on browser based interactive 3D visualizations, we present a set of existing systems applied in Finland, and discuss their common properties and differences. To obtain first-hand experience, we experiment with an online 3D application development platform. 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 framework for discussing browser based 3D systems, covering the spectrum of possibilities available in modern web-based 3D for built environment applications.

Highlights

Digital 3D models have become a central tool for geo-information, being built to a wide range of cases in varying extents, structure and style
Several authors have discussed this in 3D city models (Biljecki et al, 2015), virtual geographic https://doi.org.0.30672/njsr
The overview visualization utilized an area model generated automatically from open geospatial data sets. It provides a simplistic visualization of the area, with simple 3D building and road surface models

Summary

Introduction

Digital 3D models have become a central tool for geo-information, being built to a wide range of cases in varying extents, structure and style. In the context of the built environment, 3D city models, combining geometric and semantic information, are a significant research theme In Architecture, Engineering and Construction (AEC), the focus of modeling has often been an individual building or a site, rather than the whole urban area 3D models have been used in geomorphology (Alho et al, 2011), maritime safety (Goralski et al, 2011), and landscape planning (Wack & Stelzl, 2005), to name but a few examples. One of the central use cases for 3D models is visualization. Several authors have discussed this in 3D city models (Biljecki et al, 2015), virtual geographic https://doi.org.0.30672/njsr.67846
