wrapping text around a cylinder

[Matthieu Hendriks]

How can I wrap text around a cylinder, I tried wrap(2) or wrap(50)  on a text object but if stops rendering at 250/1000 or 500/1000.

A working example would be nice. :)

Something like this?

from openscad import * fa=2 fs=0.1 r=10 cylinder(5, r, center=True).show() (text("Round and round we go!") .linear_extrude(0.5) .rotx(90) .wrap(r) .color("gray") .show())

I also noticed hanging at 500/1000 when I did something else. Perhaps going negative on one axis or the other?

If you can reproduce the hanging it would be nice if you could create an issue on GitHub so we could look into this.

I presume it will finish any time in the future.

fs=0.1 and fa=2 generates just huge amount of data.

if you comment both values and go with defaults, it finishes almost immediately.

Question to us is: does it make sense to  print a warning about a huge calculation effort approaching ?

Guenther, I don't think that's the issue here. What I rendered above takes 50 ms on first render, 10 ms subsequently, and that's on a 15+ year old computer. And I used way simpler geometry when hitting the bug, like a cube or low-res sphere.

Sure Michael, I'll file an issue if I get around to making a repro!
