Hi everybody! i’m new here and i’m sorry but i need your help! i’ve to design a parametric dome with a triangular pattern (planar triangles) like this one 06 [dome] where i can decide with a slider the “UV” division and calculate the total surface but i don’t know how i can do it. can anyone helps…

Using the other method to generate the icosahedron… GeodesicSphere3.dyn (6.6 KB) [image] //Icosahedron p=(1+Math.Sqrt(5))/2; a=Point.ByCoordinates({0,0,0,0,p,-p,-p,p,1,-1,-1,1},{1,-1,-1,1,0,0,0,0,p,p,-p,-p},{p,p,-p,-p,1,1,-1,-1,0,0,0,0}); b={{a[0],a[8],a[9]},{a[0],a[9],a[5]},{a[0],a[5],a[1]},{a[0…

Are you trying to make a geodestic dome?

I need to practice my geometry skills more often. This is as close as I got. My dome is definitely not geodesic in nature: [2015-12-09_17-44-02]

I’ll be starting a project in a couple months which will draw upon methods of parametizing a sphere to complete. It bares mentioning for the public at large who stumble onto this thread the mathmatical description of parameterization calls for equilateral triangles (or related pattens) be used to ma…

@DIMITAR VENKOV thank you so much! i think it is just what i need! i will see with my tutor :wink: and another little thing, if i want to cover every triangles with a surface and calculate the total surface of the dome (made by triangles) and the number of the tringles that aproximate the dome? how…

You can use the same points, that you used to define the chords, to define the faces. I’m not sure if I should show you how to do that because this is your thesis and I’ll be doing you a disfavor if I give you a solution straightaway. If you face specific difficulties, I’d love to help you with thos…

@DIMITRAV thanks a lot!!! no don’t worry…my tutor tell me to ask it in this forum because is the first time that me and him use this program and in internet i didn’t find anything about domes in dynamo! I ve another question but first i’ll try to myself ^^ thanks!!!

@DIMITRAV I swear…it’s one day that i try to do it without any results the problem is that i never use the design script so for me is very difficult to understand it. I try to find something about it on internet but i didn t find anything! Please help me…just to understand the process. CC

Here is a half done definition with nodes. Hope you figure out a way to complete it. File: dome-partial.dyn [20151212-1]

Geodesic sphere… To confirm with the spirit of this thread, not posting the definition yet :stuck_out_tongue: [20151213-2]
