The authentic display of shadows by modern video games has long become a matter of course. On the web however, this is somewhat different: the rendering of three dimensional scenes in the browser has only in recent years been on the rise. At best, shadows have only played a minor part in that development, despite their importance regarding recognition of spacial relationships in human vision and general increase of a scene's authenticity. An important part in the development of web-based 3D is played by the open-source JavaScript framework X3DOM, as it provides an approach for the integration of declarative 3D in HTML5. However the framework too only offers rudimentary shadow rendering techniques that hardly meet today's demands. This work tackles this issue by first examining existing shadow mapping techniques for their suitability in the web context and based on that developing and implementing a concept for the enhancement of shadow display in X3DOM.
