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!
See this StackOverflow issue and answers.
Also see #1569.
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.
