Paper Abstract:	To address the realistic problem of visualizing the surface field of objects with complex geometry in volumetric datasets, we present and implement an efficient surface clipping method for visualizing significant field data on arbitrary object surface. This method first applies the surface-volume intersection equation to clip the volumetric data and transforms volume cells of the dataset to 2D plane. Then, a clipping algorithm for concave and convex polygons with several optimizations is specifically designed to accurately solve intersection polygon and its corresponding field value. Finally, this method is integrated into a visualization software to enhance the visualizing capability. The experimental results demonstrate that our method can efficiently and accurately achieve the surface clipping operation of complex geometry from volumetric datasets.
