Create editable sphere from Py-Generator? [SOLVED]

I have been searching for some time but cannot find a simple answer to this that actually works for the Python Generator:

How can the Python Generator create a sphere and then make it editable, so it is no longer a primitive?

Thanks,

Hi.

as far as I know, the Python generator don´t let you insert a converted polygonal version, offhandedly.
You can write your own Sphere object or use this workaround;
The generator has some userdata to manipulate the sphere and a child object which stays every time updated.
Like this example:

  
import c4d  
from c4d import utils  
  
  
def main() :  
    
  obj=c4d.BaseObject(c4d.Osphere)  
    
  # check if there is allready userdata for the python generator  
  # just to begin with something; insert userdata for the radius of the sphere  
  if  op.GetUserDataContainer() == []:  
      radius=c4d.GetCustomDataTypeDefault(c4d.DTYPE_REAL)  
      radius[c4d.DESC_NAME] = "radius"     
      op.AddUserData(radius)  
      radiusvalue = op[c4d.ID_USERDATA,1]  
  else:  
      radiusvalue = op[c4d.ID_USERDATA,1]  
        
        
  #set the sphere to the user given radius      
  obj[c4d.PRIM_SPHERE_RAD] = radiusvalue  
  
  
        
  #convert to a polygonal object  
  newobjList = utils.SendModelingCommand(  
                          command = c4d.MCOMMAND_CURRENTSTATETOOBJECT,  
                          list= [obj.GetClone()],  
                          mode=c4d.MODELINGCOMMANDMODE_ALL,       
                          doc = doc)  
                            
  
  #instead of letting the generator creating an object directly  
  #do this set and replace code for your polygonal object  
  if op.GetDown()==None:  
      doc.InsertObject(newobjList[0],op)  
  else:  
      obj_2=op.GetDown()  
      obj_2.Remove()  
      doc.InsertObject(newobjList[0],op)  
        
  return

But I´m not sure if this is the best solution.
I´m really interested, if there is a better way to solve it.
There was another post with a circle object lately.

Edit:
the geometrical manipaltion of the sphere will be gone after the generator refreshes the sphere.
It´s just a replacement.
if you want real procedural geometrie watch out for the Houdini integration.
or Fabric engine at the beginning of 2015.

Great! This is exactly what I was looking for. Thank you so much for taking the time to explain that for me.
