This is my test render for the model, textured with V-Ray, non-scripted texture

So basically this is my base script for the circles

import maya.cmds as mc
import math
import random

def cubeSphere():
    myCubeList =[]
    for each in range(2000):
        myCube = mc.polyCube(name="myCube")
        mc.move (10 , 0 , 0 , myCube[0])
---------------------------------------#
as shown, mc.move helps me to get a radius of 10 after I apply the rotation command below since it will allow the cubes to move away from the world pivot
     

     
        rot= random.uniform (0,360)

---------------------------------------#
the random unifrom from 0, 360 allows the cubes to appear between 0 to 360, since I have about 3000 cubes, the cubes would overlay and form a basic circle. Well since I want a sphere instead of a circle, I would go for the 3D instead thus a base which is my Y is needed and Z axis is needed to form a sphere around the base in a range of 3000 cubes. And since the pivot is world axis, I needed another dimension to make it a sphere, thus I had to use Z axis or else using X axis would just form a circle on a plane

        mc.rotate ((0),(each*rot) ,(each) , myCube[0], pivot =(0,0,0))

------------------------------------------#

then the commands below basically helps me in randoming the size and height of the cubes

        ranSize = random.uniform (0.01,1)
        ranHeight = random.uniform (1,3 )
        mc.scale ( ranHeight, ranSize , ranSize)
     
     
     
     
     
     
        myCubeList.append(myCube[0])
    return myCubeList
 
myCubeList = cubeSphere()
print myCubeList

Previously I've tried by applying cubes onto the vertices to create the effect, but it doesnt work well since it has more of a uniform effect rather than random
import maya.cmds as cmd
import random


import maya.cmds as cmd
import random


mc.polySphere (n="name")
VtxList = mc.getAttr ("name" + "vtrs". multiIndices = True )
(The command above allows me to select the vertices in the Sphere)

for vtx inVtxList:
 vtxPos = cmd.xform(vtx, query = True, ws = True, t = True)
vtxName = "name.vtx("str(each)+"]"
(So basically I check for the positions for the vertices existing in the selected object which is my sphere)
 replaceVtx = cmd.polyCube( h=0.1, w=0.1, d=0.1 )



 #replaceVtx = to the object that I want to replace it on
 cmd.move(vtxPos[0],vtxPos[1],vtxPos[2],replaceVtx)

However the results is too uniform

So I had to go back to the previous trial I had by using random along rotation 0 to 360

def cubeSphere():
    myCubeList =[]
    for each in range(2000):
        myCube = mc.polyCube(name="myCube")
        mc.move (10 , 0 , 0 , myCube[0])

       
        rot= random.uniform (0,360)
        mc.rotate ((0),(each*rot) ,(0) , myCube[0], pivot =(0,0,0))
myCubeList = cubeSphere()
print myCubeList

For this whole function, it basically creates a round circle around the world 0,0,0 axis
If the values in the X axis in mc.move changes , the radius of the circle changes since the circle grows towards the x axis.
While in mc.rotate, in Y axis creates a circle rotation of the cube to follow since the rot* range is from 0 to 360.

However now it only creates a circle in the X axis thus if i need it to form a sphere shape I would have to alter the stuff on the Z axis. Meanwhile any numbers as long with rot* would create a circle as shown below with only the circle shown will be in different axis

Result:

Approval For Python Scripting

This is my base idea and reference for my python scripting which is random cubes on a sphere. I am currently trying by using vertices to form this, or might be using random rotation towards the centre pivot of the circle, depends on which would give me the better result.
