for choosing the series of line tests for a single point, how do you know which order to feed in the point 1 and point 2 into the L equation? i know the order matters among p0, p1, p2 for the three line tests but i can't seem to figure how to tell what that order should be.

The order should be counterclockwise according to these equations. For this slide, p[i] is p2, so p[i+1] is p0
