sign

s2 s2predicates

A more efficient version of Sign that allows the precomputed cross-product of A and B to be specified. (Unlike the 3 argument version this method is also inlined.)

  1. int sign(S2Point a, S2Point b, S2Point c)
  2. int sign(S2Point a, S2Point b, S2Point c, Vector3_d a_cross_b)
    int
    sign
    (
    in S2Point a
    ,
    in S2Point b
    ,
    in S2Point c
    ,
    in Vector3_d a_cross_b
    )
