【Abstract】 This paper discusses the validity of triangulation between two polygons on parallel slices,giving a definition to the valid triangulation between two polygons. Thus a conclusion has been drawn: The validity of a triangulation is not affected when one of the polygons is translated along the normal of the slice, or translated on the slice, or scaled with the same coefficient on the slice.更多还原
