Abstract
Texture-based volume rendering is a technique to efficiently visualize volumetric data using texture mapping hardware. A method is presented that extends this approach to render shadows for the volume. Although the method does not perform lighting calculations, the resulting image has a shaded appearance. As calculating the shadows is independent of the visualization process, the method can be applied to any form of volume visualization.
