Well I just slapped together a primitive to simulate twisted string bits but
am not all that pleased with it.

The string I have in mind to model will be so tight that a straight line
will be fine, no need for catenary curves (although it sure SOUNDS neat...,
or at least close enough for POVray purposes.

What are you using for primitives to model the individual sections of
string? I used a square section that was twisted 45 degrees from one end to
the other but that may not have been enough sides to get a good look. (my
first ever "primitive" Yaay!)

Is cad.dat a better place to discuss? All these years and I still never can
tell for sure.

(...) Perhaps we could also have parts, like the hose segments so you have a "String End" and "String section" (for want of better names). These could possibly be cylinders with a "wound" or "braided" pattern on them, the end section having 1 closed (...) (22 years ago, 10-Apr-02, to lugnet.cad)

(...) Nah, the .dat.* groups are for posting .DAT content and followup discussions. If you are going to post an example string element, the .dat.parts would probably be a good choice. Fredrik (22 years ago, 10-Apr-02, to lugnet.cad)
