algorithmic modeling for Rhino
I´m an architect interested in a developable surfaces method from 2 edge curves (lofted surface solver) for a roof project. (like Lorenz Lachauer method, but it is not released yet.
Any info would be appreciated.
Ok, I gave it a go
It is working by letting the points slide along the curve while applying a force planarizing each quad. I had to put some short range collision interactions between the points to stop them crossing over, and I think that is what is causing those regions of curvature near the ends of some of the quads. I think if they are allowed to become triangles it might solve this.
So I'll have to try and find a better way of preventing the points crossing each other along the curve.
By the way - do you have any sample pairs of curves I could try this out on ?
Thank you very much for your effort Daniel.
This is the vimeo link solver i would love to test:
As you can see, i don´t mind the pair of curves changing, only want a developable surface from aproximate to the initial ones.
I tested your tapeworm script and is nice, but i have some difficult to find "similar" preset surfaces (from my architectural roof project). Is a little hard...
Of course, i link the .3dm file with one pair of curves
Thanks again Daniel, and excellent work.
Still a few things to fix before I release her. To be honest it was not really a piece of cake, I started this def on version 0.5... before data trees blossomed.
Here is the method:
divide both curves A and B.
For each point pA on curve A,
you need the corresponding tangent vector tA on curve A, and the lists of "cone" vectors pB(j)-pA and tangent vectors tB(j) on curve B. so you have three vectors tA, tB(j) and AB(j)
these three vectors define a parallelogram thas varies along j
So you just need to plot the curve 3Ddet = f(pB) , still for each point on A
'pB is the parameter here'
You can manage double solutions or cusps directly on the plot by using clostest point and >= conditions to kill unwanted results.
The videos you posted are interesting. I don't understand how it works with just 2 slider to tune the curves.
My week holiday has been fruitful. I'm nearly there!
I've added a couple features and foud a way to use galapagos.
Honestly...i don´t know how to use it....
Seems to complicated to test it for my level, could you help a bit?
Hi, did you get any workable results with two curve developable loft optimization and fabrication of the results? I'm trying the same thing and I was wondering it you got any success and can share it. Thank you in advance.
