Two new algorithms for line clipping in E² and their comparison

Skala V., Hui B. D.

Machine Graphics and Vision

2000

Vol. 9, No. 1/2

297-306

New efficient algorithms for the line clipping by the given rectangle in E² are presented. The first algoritm is based on the line direction evaluation the second one is based on a new coding technique of clipping rectangle's vertices. It allows solving all cases more effectively. A comparison of the proposed algorithms with the Liang-Barsky algorithm and some experimental results are presented, too.

Faster algorithm for line clipping against a pyramid in E³

Skala V., Bui D. H.

Machine Graphics and Vision

2000

Vol. 9, No. 4

841-850

A new algorithm for line clipping against a pyramid in E³ is presented. The suggested algorithm is based on the use of a separation function and avoids conmputation of intersection points that are not endpoints of the output line segment. It also allows to solved all cases more effictively. The performance of this algorithm is shown to be consistently better than the traditional Liang-Barsky's algorithm for line clipping in E³. Experimental are also presented.
