help, geometry orientation of a surface grid?
3 Replies
Basically, i divided the surface into a grid and then assigned a geometry to each point of the grid. However, they do not fall flat on the surface, instead, they are always parallel to the xy plane.…Continue

"Hey Damien,
That is quite an interesting solution... I had tried doing it with trees, I got to the halfway point in your solution (easy, as the points are stacked in columns along V), but I couldn't figure out how to path the U stuff...
I…"
Vicente Soler replied to michelle's discussion how to cull off the edge points of the grid?"Usually when people ask for removing the points in the edges, what they really want is the center of the imaginary cells that would be generated when subdividing a surface. The Divide Surface component gets the corner points of these imaginary…"
David Rutten replied to michelle's discussion how to cull off the edge points of the grid?"Absolutely, my solution is a lot slower than directly generating culling patterns. It is however pretty flexible in that it isn't limited to just edge curves (any geometry will do).

Damien Alomar replied to michelle's discussion how to cull off the edge points of the grid?"I answered in another thread....

David Rutten replied to michelle's discussion how to cull off the edge points of the grid?"Another solution would be to duplicate the surface edges, measure the distance from each point to the closest edge (Pull component), and if that distance is very small, we assume the point is on the edge. So create a culling pattern from the…"
"Well, since nobody answered yet... attached is a rather complicated definition (I'm sure there's a simpler way) with two possibilities - 1) cull just the corner points and 2) cull all the 4 edge point sets. FWIW... --Mitch"
Damien Alomar replied to michelle's discussion help, geometry orientation of a surface grid?"Removing the edge points requires two operations. The first one is just trimming the first and last point from each list, which can be done with the subset component. The second one is actually removing the first and last branch from the tree of…"

michelle replied to michelle's discussion trimming surfaces or boolean difference?"hi Matt,
I think it will be applied to flat but triangular shaped surfaces. like the break down components of the octahedron.
I will keep working on it and i will be very happy if you can help me during the weekend :)
thanks a lot again and good…"
Matt Gaydon replied to michelle's discussion trimming surfaces or boolean difference?"Hi Michelle
Do you still me to try and simplfy the code you posted today as it seems you have move vectors/points than you use or even need which is making simplfying it interesting to say the least. With time your codes will become more simple for…"
michelle replied to michelle's discussion trimming surfaces or boolean difference?"Hi Matt,
You got me wrong, I meant its that your way of building is much better than mine cuz mine looks too repetitive. I love your code.
The shell one is very impressive. I meant, yeah, Im impressed.
I think if it can be put on a surface, (a…"
Matt Gaydon replied to michelle's discussion trimming surfaces or boolean difference?"Hi Michelle
would not let me reply to your latest question on simplying it. do you not like my code :(

- the set of points are generated by rhino tho. So no need to figure out the math of the distance and angle between the points.

- yes, Matt. It sounds great. I do have skype "a6michelle2000". But for tomorrow, I have an appointment at 1pm so its like 7pm ur time. I think i can be back around 9pm ur time. Dont know if its ok for you or just another day.
The shell is not important for the facade, its just very heavy. (But its so great for the inner structure, Thank you!!!)
Which city in Germany r u? Where r u from tho? I'd love to visit you, your firm and your projects!
Well, sorted out. not really, cuz its statics. Cant really animate:(
Thanks so much, Matt:)

- Hi Michelle
Those renders are amazing really like what you have done with the module.
Now we have got this wall to wall thing sorted i will be able to help a bit faster i had a look at your defintions today quickly.... Thats a lot of code!!!
I'm off out tonight (in about 10 mins) but can work though converting your manaul system into GH tommorrow as all that i require is a little bit of working out of the grid spacing and you can have a simply(ish) version in GH. with or with out Shelling system i will be free in the early evening so from about your lunch time onwards. Do you have Skype as then can work cross contentinents easier.
If your comming to Europe in the summer do come and say hello as just secured second internship out here till end of August. (maybe able to show you some of the projects too ???)
Good to know you got it sorted some how.

- Hi michelle
Just looking at some thing on my page and realised that never heard any more from you so though i would look on you page and see if you had finished it without me, only to find a reply on your page back to me which i never got as its on your own wall so does not tell me about it.
Sorry the final code i left you with would not work as you wanted it too and i reaslised this a few days later when i had another chance to look at it, i have since re-written the code fixing all but a spacing/ rotation bug as not sorted out all the maths for that yet which works of a grid of points fine. and can change the scale of the core on each on slightly differently.... But i realised if i keep giving you super optimismed code that would be hard to convert into your own work you maybe lose marks. So i stoped posting developments till i got a reply. Sorry if this caused you chaos when i just left you the complex code and no more help.
Have you finished the project now or would you still like help?
Yes i am living and working our here for a year as an architectural intern.

- Good evening Matt,
I was trying to but did in a dumb way. very repetitive. It can do the work but if i want to put it in a 100 pt grid, i cant do it this way.
I trying to modify using two dif ways but i think i miss something. like split or tree i dont know.
Take a look of the file?
the points are in done in rhino for the sake time (that its easy to convert to grasshopper). But i dont know how to do the replica of the octahedrons in grasshopper and each of them to transform according to the external forces. (like the one that i disabled)..
r u like in, Germany?2 sets.3dm2 sets.ghx

- Afternoon Michelle
Though i should write here as thread has gone so offtopic from original question asked as your project has developed.
Have you had any luck with doing any of the following using any of your codes or mine and if not would you like any help as i am free now.
Have you been able to either
*populate a surface with the original module (Single finished lofted or shelled module is orientated from origin to plane of surface)
* Write/convert code to make a module at a set points on the surface (Each module is inderpendnt so Scaling can be different for each one even though its own written in a scingle line of code not one for each module.
* Create and Bake a series of internal scale changing modules that are each rotated though x,y,z axis then populate these on surface depending the vaule at that point on the surface
Matt
P.s i worked out how to do a TRIM in place of the loft so it is much more like your orginal definition but its very processer heavy and slow so would not adive using it.
