al structure that might resemble the shell structure of radiolaria - www.radiolaria.org - and then I want to manufacture it via 3D printing. Do you think mesh will be up to it?
Also, whether the mesh will work or not, could you please explain me the process on how you arrived to the mesh i.e. why you used all these components that you have used in your definition? As I do not want to directly copy and paste it, I want to understand on why you used all the other components to arrive to the resulting mesh. This will be a huge favour.
Knowing that the form that i have created is very important, do you think starting with the curves was the right thing or do you have any other way in mind to achieve this form with XYZ parameters?

Ja du hast Recht, ich sollte meine Fragen das nächste mal isoliert hochladen. Sorry für die "wirre" Datei.
Dennoch muss ich echt sagen, dass ich es mega schade finde, dass es einige in diesem Forum gibt die einen echt "runtermachen" indem sie ständig auf Fehler hinweisen und einen für komplett bescheuert halten. Es fällt eben nicht jedem leicht ein Programm ohne zusätzliche Hilfe sondern nur durch Ausprobieren zu erlernen. (Musste ich mal kurz loswerden!) Gut, dass es auch solche wie dich gibt, die einen Mut machen.
Gruß und nochmals Danke!…
p; 3D Urban ModelingOn the topography subject I get the next message: "One or more boundaries may be outside the bounds of the topo dataset" I'm not sure if it's the .IMG file I'm loading since I found so many IMG files nearing my polyline area (Miami Lat:26 Lon:-81 aprox.) or maybe my polygon doesn't match the topo area? I have no idea why it isn't working :(On the Shapefile subject, haven't been able to find a Building Height SHP File, so far have downloaded around 8 SHP files which only contain Polylines, my solution is to meanwhile randomize Z heights, but of course this data is not "technically" correct.P.S.: I've already tried all example links and also the ones posted by you and Benjamin in this video.Been strugling last few days, hope you can help me, thanks in advance!!…
at 0.85m above the floor.
I copy paste from the Appendix E:Rights to Light of the book "Paul Littlefair, Site Layout Planning for Daylight and Sunlight, A good practice, BRE Press, p.60" which is the primary guide for evaluating the impact of new construction to the Rights to Light of the existing adjustment buildings:
"The accepted way of calculating the loss of light is to compute the sky factor at a series of points on the working plane. In dwellings, the working plane height is usually taken to be 0.85 m (two feet nine inches). The sky factor is the ratio of the illuminance directly received from a uniform sky at the point indoors, to the illuminance outdoors under an unobstructed hemisphere of this sky. No allowance is made for glass losses or light blocked by glazed bars and (usually) window frames; nor is reflected light included, either from interior surfaces or obstructions outside. Thus the sky factor is not the same as the CIE daylight factor (see Appendix C). The sky factor is often calculated using a Waldram diagram, but this is a different Waldram diagram to Figure B1 in Appendix B, which should not be used for this purpose."
Thought couldn't find the specific Waldram diagram for this case from the references, I assume contemporary analytical tools should exist to calculate it.
I used your Vertical Sky Component process and culled the mesh faces lower than 0.2% but I believe because of they type of the radiance analysis as you have explained it before (stochastic method) it doesn't create one continuous edge, as you can see in the attached image.

perforations that sift the light and with joints that are put together by
hand, it serves as a focus point in the big courtyard while visitors can
relax in the shade.
The pavilion is parametrically designed in Grasshopper and Rhino, and
loads, sun and shade, and material use has been optimized.
Steel sheets of 2 mm have been laser cut and rolled at the factory and
then assembled by hand in situ.
After summer the pavilion will be standing at Chalmers University of
Technology during the autumn, after which it is possible to purchase it.
The pavilion is a collaboration between Röhsska museum of Design, Chalmers
University of Technology and Ribo-verken, and is the result of 33
Architecture students' work during one semester, in the master level class
'Material and Detail'. After selecting one initial design, 33 students
have worked to develop the design, and to turn the project into a pavilion
which is safe and constructable.
The purpose of the course is to explore digital fabrication and to turn it
into a real, built architectural project.
Words on the design:
When talking to the staff at Röhsska at our first site visit, it became
clear that the courtyard, even though at the time covered with snow, could
get extremely hot during summer days. Adding this fact to the briefs'
demand for seating and the size of the empty courtyard, we set out to
create a pavilion that provided shaded seating inside it as well as
creating shaded spaces around it to place existing chairs and tables. The
pavilion therefore creates a network of spaces with the existing furniture
that altogether manages to inhabit the large courtyard, like different
small islands in an archipelago, which together with the technique of
rolling the steel in to arc segments gave it its name.
Well inside the pavilion you can lie comfortably on the smooth surface
that uses the steels excellent possibility to stay cool wheEn shaded.
Inside you find yourself in a space, the pavilion, within a space, the
courtyard, that creates a small but secluded getaway from the hectic city
life of central Gothenburg that is just outside the courtyard. The
perforation in the ceiling spreads out an organic pattern resembling the
one you would see from a tree in the forest. Contrasting the smooth
inside, the outside of the pavilion lets the visitor study in detail how
the 133 pieces are joint together with 1535 joints with a total of 3640
bolts holding it together.

near logic you were asking:
This is simply using a line as a reference, and finds the projection of the mesh points on it. Then, the values along the line can be used to create a linear growth. A second example is then here a simple attractor logic. The closer to the point, the larger the thickening.
A last example is using the linear increase example as a start point, but then applies the sin function to it. This creates a moving wave. Note also how this trigonometric function returns on top of itself.
I hope this helps,

once all neighbors overlap, its fine. otherwise just think, they can not be too big, as they will be trimmed, so maybe say: quad size is given by the host surface BBX diagonal length. for the trimming: as long as u have no concave parts on the surface, u can trim each cell with all others. try to work with planes instead of the planar cells. that saves performance. use plane-plane intersection, then u get edge lines, which then u just need to chamfer together. u can find neighbors for each cell by i.e. (the cheapest option) neighbors are the 10 closest cells to a test cell. remember: u just need to limit the number of intersecting planes. this works for rather evenly distributed cells with little concave curvatures. i found useful a kind of searchlight strategy. think of a rotating cone. from all points currently in the cone, the closest is designated as neighbor. i know this is totally unscientific, but i hope i could help!ps. lets see this http://www.grasshopper3d.com/photo/faceted-shell…
