Plotting 3D Polygons in python-matplotlib
- by Developer
I was unsuccessful browsing web for a solution for the following simple question:
How to draw 3D polygon (say a filled rectangle or triangle) using vertices values?
I have tried many ideas but all failed, see:
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()
I appreciate in advance any idea/comment.
Updates based on the accepted answer:
import mpl_toolkits.mplot3d as a3
import matplotlib.colors as colors
import pylab as pl
import scipy as sp
ax = a3.Axes3D(pl.figure())
for i in range(10000):
vtx = sp.rand(3,3)
tri = a3.art3d.Poly3DCollection([vtx])
tri.set_color(colors.rgb2hex(sp.rand(3)))
tri.set_edgecolor('k')
ax.add_collection3d(tri)
pl.show()
Here is the result:
