Not sure correct or not

Thanks but OV is not equal to OC necessarily. V is just a direction . For sure a.V =OC for an unknown amount of a.
Maybe I should change V to D in my answer. V(Xv, Yv, Zv) is direction vector starting from O. D is the point when the vector starts from B.
This might help. But D is not given unless you say D=a.V and then you have to find "a" as well.
Do you mean V(Vx,Vy,Vz) is just a unit vector? BV=a*V?
If so, I don't think there will be any solution.
Or if you already have the answer, please share.

Yes you are right V(Vx,Vy,Vz) is just a unit vector. This is part of an algorithm that I'm trying to complete. I don't have the answer and I'm really stuck in the middle of the process. B is the only point that can reflect V vector to point C based on OB direction. Should be an answer for it.
