coordinate issue

[LeonardPatrick]

Dear hansheng,

Thank for the second version. I am wondering how to change the coordinate in such setting: x3d fixed, but to predict x2d, w2d. Now the x2d is [0,1,2,....]×[0,1,2,....]，the x3d and x2d is among[0,1]. In my case, x3d is fixed as [0,1,2,....]×[0,1,2,....]×[depth], how to normalize it? Thank you very much.
