Abstract: Volume rendering is widely used in visualizing and exploring volume datasets. In volume visualization, it is challenging to obtain desired results, because different tissue types are represented in overlapping ranges of scalar values and interesting structures will be partly or completely occluded by surrounding tissue of less importance. This paper introduces importance-driven volume rendering and gradient peeling techniques to reveal inner structures of interest. The importance of clusters is specified interactively and composited into the opacity of voxels. Then gradient peeling is performed on the clusters whose importance is greater than the user-defined threshold. This semi-automatic approach provides users with the freedom to visualize clusters of interest and the ability to peel off surface layers of the material. Experiment results show that our approach has superior capability in revealing inner structures and removing surrounding tissue which occludes the tissue of interest.
