The related code can now be found in Curve.computeFrenetFrames().
Currently, there no way to control the orientation of the extruded shape prior to extruding it along a path.
I would suggest you use modeling software to build your model, and then import the model into three.js.

Thanks for your lead and suggestion!
Extrude a variety of shape to a path3d is essential in my project, model it by extern software is futile for me. It is very disappointing if there no way to do it!
The issue of StackOverflow have mention the FrenetFrames conception which is totally fits my needs, Is there anything accord with the FrenetFrames in threejs?

4 years ago Here is the code fragment that sets the initial normal and binormal. It is based on the direction of the first tangent vector.
If you want control of each Frenet frame, then I suggest you create your own method that implements what you want.
We considered adding support for that, but decided against it because it seemed like it was a bit too complex for three.js' purposes.
I want to extrude a shape along a succession of vector3 to build pipe mesh, but I was confused how to determine the orientation of shape2d in 3d space (just like below schematic diagram show)! I guess there should is a binornal conception to control it, but I can't find parallel param in threejs extrude geometry!
