angle between two arbitrary lines

[Burak Korkmaz 0]

Hi,

I would like to find the angle between two arbitrary lines.
The plane in which curves positioned is rotated in x,y and z axis simultaneously.

Please refer to the image that I've attached. The red curves are the lines I am mentioning. Magenta line is the normal to the plane.

Best Regards,
Burak

Hi Burak,

 

you can use the tangent vectors of the two lines to calculate the angle by means of the dot product. I attached a small example. Hope this helps.

 

Cheers,

Klaus
