python读取ply数据

直接读取数据用matplotlib绘图

兔子数据下载：
http://graphics.stanford.edu/data/3Dscanrep/
或
https://www.gatech.edu/projects/large_models/
第二个打开有点慢，建议用第一个下载

import matplotlib.pyplot as plt
from plyfile import *
from mpl_toolkits.mplot3d import Axes3D

plydata = PlyData.read('bun000.ply')

xlist = plydata['vertex']['x']
ylist = plydata['vertex']['y']
zlist = plydata['vertex']['z']

fig = plt.figure()
ax = Axes3D(fig)
ax.scatter(xlist, ylist, zlist)
plt.show()

可以用MeshLab直接打开，很方便
