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.
