This paper presents a novel framework for illustrating surfaces in volume. Surfaces are illustrated by drawing only feature lines, such as silhouettes, valleys, ridges, and surface hatching strokes, and are embedded in volume renderings. This framework promises effective illustration of both surfaces and volumes without occluding or cluttering each other. A two-step approach has been taken: the first step depicts surfaces; the second step performs volume rendering, at the same time embedding surfaces from the first step. We present implementation strategies, especially those leveraging modern graphics hardware, for delivering an interactive rendering system. We also introduce Procedural Image Processing (PIP), a new method for enhancing both feature detection and depiction of surfaces. Our implementation results have shown that this mixed form of rendering improves volume visualization and is efficient.
