A Comparison of a New O(1) and the Cyrus-Beck Line Clipping Algorithms in E2

A comparison of a new algorithm for line clipping in E2 for convex polygons with O(1) processing complexity and the Cyrus-Beck algorithm is presented. The algorithm is based on the dual space representation and a space subdivision technique. The algorithm demonstrates that preprocessing can be used to speed up line clipping significantly. Theoretical analysis and detailed experimental results are also presented
