hmm. Mayavi2 has a mlab module thats under active development. It aims
to do the same stuff that matlab 3D plots do. However, svn currently
crashes for me.

from pylab import *
import matplotlib.axes3d as p3
fig=figure()
ax= p3.Axes3D(fig)
ax.scatter3D(x,y,z)
show()

this causes an error. x,y,z are valid 1D arrays. They work using the
method you've posted in your mail.

Perhaps a wrapper can be wriitten around mayavi's mlab module. 3D
plotting is too important to leave out of something like matplotlib.
Its perfect for all other things. It would be a pity if one has to
switch to gnuplot or dislin just for 3D.
