Hi guys,
I was wondering what is the strategy adopted by Mayavi when has to
render an -Inf value.
I don't know if that's the problem, but I can't see anything on the window.
Consider this code:
import numpy as np
from enthought.mayavi.mlab import *
def f(x, y):
return pow(x,-3) * y
x, y = np.mgrid[0.1:3:0.1, -2.:2:0.01]
s = surf(x, y, f)
In [6]: f(x,y)
Out[6]:
array([[ -Inf, -Inf, -Inf, ...,
Inf, Inf, Inf],
[ -2.00000000e+03, -1.99000000e+03, -1.98000000e+03, ...,
1.97000000e+03, 1.98000000e+03, 1.99000000e+03],
[ -2.50000000e+02, -2.48750000e+02, -2.47500000e+02, ...,
2.46250000e+02, 2.47500000e+02, 2.48750000e+02],
...,
[ -1.01610527e-01, -1.01102474e-01, -1.00594422e-01, ...,
1.00086369e-01, 1.00594422e-01, 1.01102474e-01],
[ -9.11078717e-02, -9.06523324e-02, -9.01967930e-02, ...,
8.97412536e-02, 9.01967930e-02, 9.06523324e-02],
[ -8.20041822e-02, -8.15941613e-02, -8.11841404e-02, ...,
8.07741195e-02, 8.11841404e-02, 8.15941613e-02]])
Cheers,
Michele.
