Normalization of Pluck coordinates

[tshooting]

First of all, I really like your work. Please tell me how to normalize the Plucker coordinates input by the network. In dataset/structured3D_train/plucker1.pkl, plucker1[:3] is not a unit vector, but plucker1[3:] is a unit vector. Does plucker1[:3] represent the direction vector? I have now calculated the direction vector and normal vector, but I don’t know how to construct it into the Plucker coordinates input by your network
