标题: 豆粑粑 mayavi 3d contour surface python

画3D contour surface，matlab，暂时是实现不了。
用python 下的mayavi2实现的，如何安装完全按官网的教程。

运行一个例子，小华丽。



  1. from scipy.interpolate import griddata
  2. import numpy as np

  4. # Create some test data, 3D gaussian, 200 points
  5. dx, pts = 2, 50j

  7. N = 500
  8. R = np.random.random((N,3))*2*dx - dx
  9. V = np.exp(-( (np.sin(R)**2).sum(axis=1)) )

  11. print "Rsize=",np.shape(R)
  12. print "R=" ,R
  13. print "V=" ,V


  16. # Create the grid to interpolate on
  17. X,Y,Z = np.mgrid[-dx:dx:pts, -dx:dx:pts, -dx:dx:pts]

  19. # Interpolate the data
  20. F = griddata(R, V, (X,Y,Z))
  21. #np.savetxt('./F.txt',F)
  22. print "F size", np.size(F)
  23. print "grid val= ",F

  25. from mayavi import mlab
  26. mlab.contour3d(F,contours=8,opacity=.2 )
