[MayaVi-users] display surface cut (solved)

[Edouard Oudet]

I answer to my question,
best.



from numpy import pi, sin, cos, mgrid
from mayavi import mlab
dphi, dtheta = pi/250.0, pi/250.0
[phi,theta] = mgrid[0:pi+dphi*1.5:dphi,0:2*pi+dtheta*1.5:dtheta]
m0 = 4; m1 = 3; m2 = 2; m3 = 3; m4 = 6; m5 = 2; m6 = 6; m7 = 4;
r = sin(m0*phi)**m1 + cos(m2*phi)**m3 + sin(m4*theta)**m5 +
cos(m6*theta)**m7
x = r*sin(phi)*cos(theta)
y = r*cos(phi)
z = r*sin(phi)*sin(theta)

# Create object, do not view it.
obj = mlab.mesh(x,y,z)
obj.visible = False
clip = mlab.pipeline.data_set_clipper(obj)
clip.widget.widget_mode = 'ImplicitPlane'
clip.widget.widget.enabled = True
clip.widget.widget.normal = (1.,0.,0.)
iso = mlab.pipeline.surface(clip)
mlab.show()
