Where the k's are normalized distances along the edge, from the edge start vertex .
This is the interpolation sceme:
v = (1 - k )* v1 + k *v2;
v1 = (1 - k1 )* v11 + k1*v12;
v2 = (1 - k2 )* v21 + k2*v22;
v11 = (1 - k11)* v111 + k11*v112;
v12 = (1 - k12)* v121 + k12*v122;
v21 = (1 - k21)* v211 + k21*v212;
v22 = (1 - k22)* v221 + k22*v222;
Substitution and reorganizing gives the expressions seen below.
