Surface hatching for medical volume data

This paper proposes a surface hatching technique for the portrayal of medical subject from volume data. By generating an intermediate iso-surface from volume data and subsequently performing surface hatching on the surface, the proposed technique provides an effective non-photorealistic approach for medical visualization. The paper covers important technical issues for the hatching including the generation of silhouettes and strokes, the computation of stroke visibility and illuminations. Experimental results are provided.
