I got this off a tutorial on the web. ( http://jmsoler.free.fr/didacticiel/blender/tutor/python_script03_en.htm )

I get error messages when I run it.

- Where in blender is “the console” where error messages would be articulated? I don’t see it.
- Any tips on how to get this to run? The site’s code for a single-square mesh works great.
- Would python version be the problem??

import Blender

from Blender NMesh import

# Some mathematical functions from the Python module

# would be very useful, but since Python is very efficient,

# it only loads the minimum that it requires.

# Thus, we must request that the math module be imported.

import math

from math import *

# Creation of the mesh of polygons

me=NMesh.GetRaw()

# Without tackling the problem of local and global variables,

# it is better (I prefer) to declare and initialize

# the variables outside of the subroutines.

i=0

j=0

# This is an example of what was explained in the text.

# The value 9 is assigned to the variable totalvert.

totalvert = 9

# Applying the results of our discussion systematically,

# the square root of totalvert is obtained with

# the function sqrt(). Notice that if the line:

# " from math import * " had not been used in the script above,

# it would have been necessary to write " math.sqrt(totalvert) "

n = sqrt(totalvert)

for i in range(0, n, 1):

# The first subroutine begins here

# with four spaces of indentation

for j in range(0, n, 1):

# The second loop begins here

# with eight spaces of indentation

v=NMesh.Vert(j, i, 0.0)

me.verts.append(v)

# End of the internal loop

# End of the external loop

# Let’s take a break before continuing

# with automating face creation.

# It’s always possible to test this script

# in its present state, but you must add:

# NMesh.PutRaw(me, “plane”, 1)

# and

# Blender.Redraw()

# we resume at the exact location in the source

# where we left off from in the previous part.

# Translate the value of n from a floating point

# (decimal) value to an integer (whole number).

# n0=len(range(0, n))

n0=int(n)

for i in range(0, n-1):

# The first subroutine begins here,

# with four spaces of indentation

for j in range(0, n-1):

# The second loop begins here,

# with eight spaces of indentation

f=NMesh.Face()

f.v.append(me.verts[i*n0+j ])

f.v.append(me.verts[i*n0+j+1 ])

f.v.append(me.verts[(i+1)*n0+j+1 ])

f.v.append(me.verts[(i+1)*n0+j ])

# After specifying the vertice co-ordinates for the

# face, it is added to the faces list of " me ".

me.faces.append(f)

# End of the internal loop

# End of the external loop

NMesh.PutRaw(me, " plane", 1)

Blender.Redraw()
