  • The advantage and disadvantage of existing slicing algorithms for stereolithography model were analyzed, and an algorithm based on the grouping matrix and the active triangle table was developed. In the algorithm, the grouping matrix and the active triangle table were established according the minimum and maximum z coordinates of the triangular facets, which reduce the times of traversing and sorting for the triangular facets and the times of intersecting with the slicing plane in the slicing processes, and which simplify the process of constructing the slice contour. By this method, the efficiency of the slicing algorithm were increased effectively.
