Wordcloud Idea

Hello I was playing with Python Generator Script by "tcastudios" and I tried to modify it (with a really limited - beginner level python knowledge ) in order to make a 3d wordcloud.
I think I have done something but it is extremely slow and if words amount less than points amount it gives out of index error. How would I make it limited to number of words in the list?
Here is my scene;

And here is code;

motexCLONE example tcastudios.com2012

motexCLONE must have a MoText Object as a child for font control.

Add a UserData LinkField for Cloner/Matrix Object.

Hi,

The Python generator is slow because it's recalculated every time it's called. In that case you can activate its Optimize Cache option. But in the case of this generator, it doesn't work well because a linked object in the user data is used as input and the Optimize Cache option doesn't check if it's been changed.
So to manually implement the optimize cache checks and verify the input linked object for changes:

At the beginning of the generator script add a global variable for the linked cloner/matrix object dirty count:

global clDirty
clDirty = 0

In main() :

global clDirty
  
p  = c4d.BaseObject(c4d.Onull)
cl = op[c4d.ID_USERDATA,1] # <--- UserData LinkField for Cloner/Matrix Object
if not cl or (not cl.CheckType(1018544) and not cl.CheckType(1018545)) :
  return p
  
dirtyCount = cl.GetDirty(c4d.DIRTYFLAGS_MATRIX|c4d.DIRTYFLAGS_DATA|c4d.DIRTYFLAGS_CACHE|c4d.DIRTYFLAGS_CHILDREN)
  
dirty = op.CheckCache(hh) or op.IsDirty(c4d.DIRTYFLAGS_DATA) or (dirtyCount > clDirty)
if not dirty:
  return op.GetCache(hh)
  
clDirty = dirtyCount
  
...

About the index error if there are more points in the array than words in the string list, you can simply use a modulo on the number of words to loop through them:

for i in xrange(pdata[1]) :
  widx = i % wl
  ...
  nr[c4d.PRIM_TEXT_TEXT] = wordList[widx]

Hello,
Thank you for your help,

I've done as you guided me here is my scene;
https://www.dropbox.com/s/mi5g490eep2qmvh/wordcloud_v02.c4d?dl=0

But still it's so slow, would you please check my scene if I have done it right?:nerd:
