generative modeling for Rhino
I have a double curved surface, which I would like to divide it into flat rectangular surfaces (Subsrf) or apply quadrilateral mesh with planer faces. I tried Mesh UV (Mesh Surface) and Sub srf, but the faces/subsurfaces are not planer. Any suggestions?
check the file. a plane is defined by 3 points, therefore a quad does not have to be planar - Srf4Pt creates planar surfaces (100%) only for three points or 4 coplanar points.
Yes, try Kangaroo or the Evolute plug-in:
You can also make this:
Make quad curved faces and then move the point number 4 to the other 3 points plane...always 3 points define a plane. Easy and effective. You can messure the deviation of every panel and make a color shader that tells you the gap size.
Try the attached paper....
It's not the best paper I've ever written, but it's a good survey of the different approaches. It was written in 2008, and some things have change since then, but the basics are the same. In order for any optimization technique (Kangaroo especially) to work, you need a good initial guess. Integrating "conjugate curve networks" will provide exactly that gues. For instance, these curve networks (created with the SPM Vector Componets btw.) will flatten nicely:
But most UV subdivision will not.
Nice to hear from you again!
Thank you very much for the paper – It is VERY useful.
I recommend to anyone interested in the subject to have a look at the paper.
“BTW” – The image above is excellent – I like it...!
