[Visualpython-users] Help: color - what did I do wrong?

[Toan T N. <nt...@ph...>]

Hi, I'm using the face object and I keep getting this error message about 
color must be the same size as pos, but I don't know how to fix it. My script 
is like this:

pos = zeros( (nface*3,3), Float)
nor = pos
col = pos

## assigning pos, nor, col here 
for i in range(nface)
	pos[i*3]=(p1x, p1y, p1z)
	nor[i*3]=(n1x, n1y, n1z)
	col[i*3]=color.red
	... # similarly for i*3+1, i*3+2

faces(pos=pos, normal=nor, color=col)


It gives me the following error

  File "/usr/local/lib64/python2.3/site-packages/visual/primitives.py", line 
301, in __init__
    process_init_args_from_keyword_dictionary(self, keywords)
  File "/usr/local/lib64/python2.3/site-packages/visual/primitives.py", line 
37, in process_init_args_from_keyword_dictionary
    displayobject.color =  keywords['color']
ValueError: color must be the same size as pos.


I tried

 faces(pos=pos, normal=nor, color=col)

It gives the same error. The only thing that works is 

faces(pos=pos, normal=nor, color=color.red)

But I want to have different color for some faces. Can somebody help? Thanks a 
lot.
