How can I make good tube with three.js? for example railings

[PavelBoytchev]

Revisiting this topic only because once upon a time I did rounded corners of polygons. Here is a demo, it may give some ideas for railings in 3D:

Help with this (almost working) code to draw arbitrary rounded polygons? ie. From a series of corner points and rounding radius?

If it is OK to have the rounding not perfectly circular, a much shorter solution is to use shapes and quadratic curves at each vertex. [image] In the snapshot, blue has radius=0 (i.e. no rounding), red radius = 2 (small rounding), yellow radius = 4 [image]
