Capturing attributes, to retain the tilt?

[Rikard Jespersen]

Hi, the idea of converting the curve to mesh, and then back again, so that we could get rid of the scaling issue. Would it be possible to capture the tilt (perhaps converting the curve to points, and capturing the data of the points?) before the conversion, and pass it to the new spline? And by doing so, not having to worry about the number of gondolas?

I have tried and failed, but I can’t get it out of my head that “it should work”. So I’m asking, is it a fool’s quest, or is it possible. It’s just that I don’t know how.

I was also thinking that aligning the rotation to the normal of the curve we’re instancing on would do the trick. But I lack the skills necessary to go from idea to reality. Or I’m just not smart enough to understand that it’s impossible.

Thanks,

Hi @carramone ,

Clever, but I don’t think that’ll work. The problem is, the way this is set up, is actually physically incorrect. What you want is something like this:

and as you can see, the inner circle, where the horizontal beams meet, is smaller than the outside circles.

In this Lesson, the inner circle has the same Radius as the outside. This results in the horizontal beams meeting at different ‘Tilts’, something like this:

So that’s why I think, that Capturing the Tilt Attribute would probably not work.

It might be better, to create those horizontal beams outside of the Mirror, something like in my first image.

Thank you , that is Interesting, I didn’t think of that. And while I can’t say I fully understand the implications, the thought struck me that if I resample the curve and add a tilt driven by the spline factor, the crossing beam should be able to be twisted and by that, fit perfectly both in the middle and, at the connectors. Perhaps it will look strange, or be structurally unsound. But from a learning standpoint it could be interesting to test.

I might just go back and try this after I finished the course. I don’t want to mess stuff up that gives me problems further down the road, so I’ll save experimentation for later on 😀

[Martin Bergwerf]

Yes! Experimenting is great!

Let us know how that goes, if you get to it.
