    • TIME AND SPACE BOUNDS FOR HIDDEN LINE AND HIDDEN SURFACE ALGORITHMS 

      Schmitt, Alfred (The Eurographics Association, 1981)
      Asymptotic worst case time bounds for three hidden line algorithms are derived and analysed. The first algorithm is a brute force solution that needs at least quadratic time. The second exact hidden line algorithm is based ...
