“…Most of these interfaces deal with the topic of smart cities, architectures, urban design, and urban planning. Three main WebGL-based commercial software frameworks are ESRI City Engine web viewer, Unity 3D [17], and Google Earth/Maps 3D [39]. They provide comprehensive Application Programming Interfaces (API) for customized project development.…”

Contemporary development of computer hardware and software, WebGIS and geo-web services as well as the availability of semantic 3D city models, facilitate flexible and dynamic implementation of web applications. The aim of this paper is to introduce 4D CANVAS, a web-based application for dynamic visualization of 3D geospatial data for improved decision making in smart city applications. It is based on the Cesium Virtual Globe, an open-source JavaScript library developed with HTML5 and WebGL. At first, different data formats such as JSON, GeoJSON, Cesium Markup Language (CZML) and 3D Tiles are evaluated for their suitability in 4D visualization applications. Then, an interactive Graphical User Interface (GUI) is built observing the principle of cartographic standards to view, manage, understand and explore different simulation outputs at multiple spatial (3D surface of buildings) and temporal (hourly, daily, monthly) resolutions. In this regard, multiple tools such as aggregation, data classification, etc. are developed utilizing JavaScript libraries. As a proof of concept, two energy simulations and their outputs of different spatial and temporal resolutions are demonstrated in five Asian and European cities. Finally, the 4D CANVAS is deployed both in desktop and multi-touch screens. The proposed application allows easy integration of any other geospatial simulation results, thereby helps the users from different sectors to explore them interactively in 4D.

“…Cesium as visualization component is used in several cases. (Krämer & Gutbell, 2015) produced a surface model visualization using Cesium's Terrain Builder. (Kim et al 2017) presented a visual extension of Cesium to visualize moving objects in a space-time cube.…”

<p><strong>Abstract.</strong> The demand of serving large 3D spatial data, mainly of urban areas, reflects the need of hierarchical data structures for 3D data. During the last years the OGC community standard I3S (Indexed 3d Scene Layer, ESRI) and 3D Tiles (Analytical Graphics, Inc.) emerged in order to deal with this challenge. Conceptually, hierarchical structures for 3D data operate similarly to web map tiles, differing only in the implementation. Although 3D hierarchical formats can transmit arbitrary sized geospatial data, they are not interoperable with consuming/visualization technologies on the client. A series of prototype implementations focus on rendering of hierarchical organized massive 3D data in various web client technologies employing the 3D Portrayal Service. As a result, the user can query a scene via the 3D Portrayal Service by specifying a spatial region, rather than a specific resource via a URI. The result is delivered either using I3S or 3D Tiles as a data delivery format, depending on which data is available for the specified region. The client APIs are capable of rendering either the I3S or the 3D Tiles content.</p>

“…See, for example Instant3DHub [Behr et al 2015]. Krämer and Gutbell [2015] evaluate some of the options for managing large urban models in current web 3d tools; Kim et al [2015] evaluate some of the options for encoding geospatial data within X3D; while, Stein et al [2014] investigate use of spatial acceleration data structure to enable larger models to be supported on the web.…”

We propose a system called Open3D, that enables collaborative curation of large-scale city models. Users of the system may view the model in the browser (left), which also acts as a social hub. Editing (middle-left) is performed using a novel parametric editing approach that is efficient and intuitive. Changes are applied back to the shared model, taking care to avoid conflicting edits (middle-right) from different users. Operations performed on one model can be retargeted (middle-right) to multiple similar models with a small number of manual adjustments. Note that the color overlays and symbols in the browser (left) are mockups of planned features.
