“…The LOD2 3D city model's streaming on Google Earth (using the KML format) was also skipped as an alternative. Although KML is native to Google Earth, the results were heavy for the data exchange [137,138]. It took until 2020 to redevelop 3D online.…”

More and more digital 3D city models might evolve into spatiotemporal instruments with time as the 4th dimension. For digitizing the current situation, 3D scanning and photography are suitable tools. The spatial future could be integrated using 3D drawings by public space designers and architects. The digital spatial reconstruction of lost historical environments is more complex, expensive and rarely done. Three-dimensional co-creative digital drawing with citizens’ collaboration could be a solution. In 2016, the City of Ghent (Belgium) launched the “3D city game Ghent” project with time as one of the topics, focusing on the reconstruction of disappeared environments. Ghent inhabitants modelled in open-source 3D software and added animated 3D gamification and Transmedia Storytelling, resulting in a 4D web environment and VR/AR/XR applications. This study analyses this low-cost interdisciplinary 3D co-creative process and offers a framework to enable other cities and municipalities to realise a parallel virtual universe (an animated digital twin bringing the past to life). The result of this co-creation is the start of an “Animated Spatial Time Machine” (AniSTMa), a term that was, to the best of our knowledge, never used before. This research ultimately introduces a conceptual 4D space–time diagram with a relation between the current physical situation and a growing number of 3D animated models over time.

“…The hyperlinks connect the WebGL builds' URLs to the 3D web service from Skylinesoft. At the beginning of 2021, the data formats GeoJSON and 3D Tiles were tested, because the cross-domain (and data transfer) problems should be solved in a more integrated way [138].…”

An increasing number of types of spatial data is possible to display and operate using only technical means of web services and a standard browser, without the need to install GIS or CAD systems. One of these types of data is data obtained with using active methods of remote sensing (as a rule, they are point clouds), full-fledged work with which 3–4 years ago was possible only on high-performance computers and specialized software. The existing web technologies allow not only displaying point clouds, but also interactively interacting with them - to perform measurements, customize display styles, combine with spatial data of other types. The purpose of the article is to form criteria and analyze the performance of software tools for creating web services for visualizing data obtained with using active methods of remote sensing. For practical testing of the selected software and analysis according to the formulated system of criteria groups, several files containing point clouds from open sources were used. The research was carried out with using the software libraries Three.js, Deck.gl, Plas.io, Potree, CesiumJS and Blend4Web. Based on the testing results, summary tables of performance and functionality were formed. The obtained results demonstrate that in terms of performance, visualization tools, basic functions for designing and analyzing point clouds, modern web services are not inferior to specialized desktop software.
