Those certainly are advantages. I just crashed MLCad trying to use it in a model
so I could play with the color so it took me a while to look at it. Honestly, I
don't think it does any better at modeling twisting than I did. I at least have
some changes in cross section as you go. But you have rounded ends which is
better. I guess now that you showed me yours I think mine is a little better.
(not much) I could submit it I guess.
I guess this gets down to this... for a feature that's what, 2 LDU total in
cross section, how much detail do you need? To model the twisted strands
accurately will take a LOT of polygons (you'd presumably use toroidal or
cylindrical sections that were somehow pieced together or something, I dunno,
haven't thought about it enough) But... Is it worth it?
This is sort of the same question you asked me about those torsos I was working
on way back when, (er, which I never finished the last one, ran into quad2dat
problems) is it necessary to have 1000 polygons in a torso print? Maybe not.
I honestly don't know.
Sometimes I wish we had an allowance for different resolutions in the same part,
the way the game engines drop polys and switch to shading as objects are farther
away, etc.
But then parts would be 19 times more complicated to model!
