The X3DOM framework [Behr et al. 2010] is well suited to present declarative 3D online in a Browser. While JavaScript libraries like jQuery UI enable intuitive interfaces and ease the manipulation of 3D contents, there is still room for better presentation concepts for certain domains like in digital heritage - e.g., by using appropriate shaders. In this regard, Radiance Scaling [Vergne et al. 2010] enhances geometric features such as tiny engravings on a 3D surface, and can be perfectly combined with other rendering techniques. The method first extracts the curvature information from the geometry and then adjusts incoming lighting. In this poster paper, we show how we have adapted Radiance Scaling to the declarative X3DOM approach, including an outline of suitable methods for calculating the curvature information on the fly in X3D/X3DOM.
