Grasshopper

algorithmic modeling for Rhino

Hi all.

I am experimenting grasshopper these days. I try to model sunshade on curve surface like esplanade theater in Singapore pic below


The paneling is by parrallelogram. it could be done by ptGridSurfaceDistance
from paneltool plugin. I tried several way to do it in grasshopper, like projection of grid point but doesn't look correct.

can anyone guide me generally on how to achieve this? I know something has to be done on uv coordinates. another question how to rotate the grid on the surface?

Thank you for your help.

Hi Ren Wei,
The divide surface by direct distance function is not ported to Grasshopper yet. We plan to export panelingtools functions at some point. Possibly when the tree structure is more stable.
I'm not sure what you mean by rotating the grid. Can you clrify?
I meant the orientation of grid relative to main axis of the roof. maybe that is just the shape of the panel


I try to manually generate the grid at moment. but I found I am not able to selection anything generated from grasshopper. I am investigating sunshade pattern according to the contour of roof so I really need the shape is variable inside grasshopper.

any reference to general algorithm to direct distance function?

Many Thanks


Quick 2hr hack, diagrid from tedngai.net/experiments.html , abit of culling here and there, the sunshading fine can be parametrically linked to sun vector. walla! esplanade

Are you from the department of architecture , NUS?
Hi Keith,

I am from NUS but not from architectural department. I was from ECE graduated two years ago. I had general interest in this sort of generative design. cause It is a way for me to approach design.

Thank you for such great reference. do u know the algorithm behind? as far as I know, the panel seems not really varied from each other. if you have spheric contour, the panel tends to be smaller towards the tip.

but sun vector is really amazing!


Regards
hey keith,
is it possible that you share the file?
ill repost it when i manage to apply the sun analyse from tedngai..

cheers

it would be great sharing the file.

Thanks for your efforts guys.
Hi Keith,

I am doing an analysis on the possibility of a dynamic sunshade and esplanade seems to be a good static sunshade local example. Im planning to run a simulation on esplanade model. I hope you can email me file too..

Thanks

hello, can you help me? about code esplanade insingapore,
come from vietnam, i am student of architect. in vietnam grasshopper is developing in university. in this time i have 1 project in my school. can you sHARE me code grasshopper about ESPLANADE MAIL:TS_PTD_KTS2003@YAHOO.COM

Hi! I am trying to build the skin but somehow I can't divide the surface in same area. Could you share me how you do that? Thank you very much!!

This is a great script, good work! It helped me get over some issues I was having.

Hey Keith,

        I'm a NUS architecture student and currently exploring parametric designs. is it possible that you share the file? my email: chenzy333@hotmail.com

Hey Keith

my name is yahia i'm studying architecture & this is my final year , could you help me by sending the definition to my email

this would be so kind from you & it'll be very helpful to me
