vector convert to xyz degree to rotate object

[katosa]

hello

I would like to ask about if i can use vector to make object rotate.

here is the scene I am working on.

I get vector from point 0 and 1.

and want to use that to rotate tube along 0-1 line.

I am not strong at math. and I want to know  which function I should use to change vector to xyz degree. 

thank you for reading.

Hi,

You can use the dihedral function:

vector p0 = point ( 1, "P", 0 );
vector p1 = point ( 1, "P", 1 );

@orient = dihedral ( { 0, 1, 0 }, normalize ( p1 - p0 ) );

Position wise it's up to you if you want the tube to sit on point 0 or point 1, be centered to the line, or just rotate.

hi thank you very much for the reply. I am trying to do so.

How do you apply @orient for tube rotation??

thanksfully I could rotate tube. 

still wish to know if vector xyz can be converted to xyz rotation degrees so that I can use in parameters in transform node.

Yes, you can convert @orient with the quaterniontoeuler() function, which will give you the rotation values in radians. You can then convert them to degrees with the degrees() function.

thank you very much. I could get the degrees.
