Function

Task

make a component to orient object in circular array

• use <obj> <radius> <count> as input data
• make a function that orient object with polar coordinates

Pipeline

• import
  • import rhinoscriptsyntax
  • import math
• function (orient object with polar coordinates)
  • calculate x,y from theta and radius
  • return x,y as Point3d
• main process
  • copy object to move
  • calculate theta from counter
  • get x,y as Point3d with function
  • move copied object with Point3D

Hints

#import rhinoscriptsyntax
#import math

#define function named "polarCoordinates" with two arguments angle and radius
    #calculate theta in radians from degrees
    #calculate x with theta and radius
    #calculate y with theta and radius
    #make point at x,y
    #return point

#declare list named objs

#loop from i=0 to count
    #define angle in degrees
    #copy object to move
    #get target point to move by using function above
    #move object to move with target point
    #add moved object to objs

#substitute objs to a

Data Tree

Task

make a component to orient multiple objects in 3D matrix

• arrange objects in DataTree
• use <objs>(obejcts to move) <x>(x bound) <y>(y bound) <z>(z bounds) <step>(distance between each cells) as input data

Pipeline

• import
  • import rhinoscriptsyntax
  • import clr and add “Grasshopper” to references
  • import GH_Path and DataTree
• main process
  • copy objects to move
  • make moving Point3d
  • make path with loop index (i,j,k)
  • append copied objects to datatree with path

Hints

#import rhinoscriptsyntax
#import clr
#add "Grasshopper" to reference of clr
#import GH_Path
#import DataTree
#import System

#declare tree as datatree

#loop from i=0 to x
    #loop from j=0 to y
        #loop from k=0 to z
            #make copy of objects to move
            #make Point3d for moving
            #move copied objects with Point3d
            #make path with i,j,k
            #add objects to tree

#substitute tree to a

 Rhino Command

Task

make a component to unroll object

• use <obj> <active> as input data

Pipeline

• import
  • import rhinoscriptsyntax
  • import Rhino
  • import scriptcontext
• main process
  • get object ID
  • get geometry and attributes from object ID
  • go to Rhino workspace
  • bake object to Rhino workspace
  • select object
  • unroll object with Rhino Command
  • go back to grasshopper

Hints

#import rhinoscriptintax
#import Rhino
#import scriptcontext

#check active or not if yes then run the code bellow
    #go to grasshopper work space
    #get real object from object ID in grasshopper
    #get attributes from real object
    #get geometry from real object
     
    #go to rhino work space
    #bake object with geometry and attributes
    
    #select baked objects
    #unroll it
    #delete it
    
    #back to grasshopper work space
