This is for the bvh exporter. My angles are incorrect. An example would be (4,3,1) to (5,8,9) I would like the angles in theta x and theta z cord system. If no one has that piece of code I know that Tan-1 would work.

at first you have a difference(delta) between two points.
(this subtract move two points that one point is at 0,0 and the other is dx,dy)
dx=x2-x1
dy=y2-y1

with atanfull you should get a angle in degree.

you can get a angle from
x,y
y,z
x,z

actually i tried that and I think I like the look at object option works better.

but it looks like the cylinder is not pointing to the next point. but it makes the correct angles at least
