[with patch, needs review] plot3d fails with
'IndexError: list index out of range'
Comment:
Here's a patch. I was getting an index error in the last line in this
code snippet:
{{{
span = len(texture) / (max_z - min_z) # max to avoid
dividing by 0
parts = P.partition(lambda x,y,z: int((z-min_z)*span))
all = []
for k, G in parts.iteritems():
G.set_texture(texture[k], opacity=opacity)
}}}
The function g(x,y) described above is discontinuous at various places,
and I think this was making the {{{k}}} in the last line of this snippet
equal to 128 while {{{len(texture)}}} was also 128. Changing the
definition of {{{span}}} in the first line, as this patch does, I hope
should make {{{k}}} always strictly less than {{{len(texture)}}}.
