title: Plotting 3D Polygons in python-matplotlib
body: <h2>I was unsuccessful browsing web for a solution for the following simple question:</h2>
  <p>How to draw 3D polygon (say a filled rectangle or triangle) using vertices values?
  I have tried many ideas but all failed, see:</p>
  <pre><code>from mpl_toolkits.mplot3d import Axes3D
  from matplotlib.collections import PolyCollection
  import matplotlib.pyplot as plt
  fig = plt.figure()
  ax = Axes3D(fig)
  x = [0,1,1,0]
  y = [0,0,1,1]
  z = [0,1,0,1]
  verts = [zip(x, y,z)]
  ax.add_collection3d(PolyCollection(verts),zs=z)
  plt.show()
  </code></pre>
  <p>I appreciate in advance any idea/comment.</p>
  <p><strong>Updates based on the accepted answer:</strong></p>
  <pre><code>import mpl_toolkits.mplot3d as a3
  import matplotlib.colors as colors
  import pylab as pl
  import numpy as np
  
  ax = a3.Axes3D(pl.figure())
  for i in range(10000):
      vtx = np.random.rand(3,3)
      tri = a3.art3d.Poly3DCollection([vtx])
      tri.set_color(colors.rgb2hex(np.random.rand(3)))
      tri.set_edgecolor('k')
      ax.add_collection3d(tri)
  pl.show()
  </code></pre>
