| Abstract | Texture-based volume rendering is a technique to efficiently visualize volumetric data using texture mapping hardware. In this paper we present an algorithm, that extends this approach to render shadows for the volume. The algorithm takes advantage of fast framebuffer operations modern graphics hardware offers, but does not depend on any special purpose hardware. The visual impression of the final image is significantly improved by bringing more structure and three-dimensional information into the often foggyish appearance of texture-based volume renderings. Although the algorithm does not perform lighting calculations, the resulting image has a shaded appearance, which is a further visual cue to spatial understanding of the data and lets the images appear more realistic. As calculating the shadows is independent of the visualization process it can be applied to any form of volume visualization, though volume rendering based on two- or three-dimensional texture mapping hardware makes... |
