3D technology has become ubiquitous: Every recent smartphone has hardware support to display graphics and with the advent of WebGL, 3D technology has finally arrived in the majority of web browsers. This allows researchers to publish their results including synthetic or captured 3D data and to present it to a broad audience. However, creating interactive 3D applications remains a challenging task requiring expert knowledge. With XML3D there exists an extension to HTML5 that allows describing 3D scenes within the website. This enables web developers and designers to participate in the development of 3D applications.


This paper illustrates how XML3D and related web technologies were used to develop a fully interactive kiosk application that allows exploring the 3D city model of two different eras of the historic Saarlouis, a fortress city constructed by France's famous military engineer, S├ębastien Le Prestre de Vauban.
