Python(x,y) 2.6.7 Mayavi "Light" Error #722

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Python(x,y) 2.6.7 with Mayavi version 4.3.1 at windows 8.1(x64 platform)

and no additional plugins have been installed, Python(x,y) installed with 
Default settings, Default path and Full components, installed for "all 
users",logged in python (x,y) as a regular user.

with this version python(x,y) and Mayavi, the 3D render may have some problem 
with the "light", by changing the #232 line in light_manager.py  
from 
self.sourcs.color = val

which light_manager.py is located at:
..\Python27\Lib\site-packages\mayavi-4.3.1-py2.7-win32.egg\tvtk\pyface

after switching the qt api to api #2, and enter the python code below may 
reproduce the "Light" error,

#--------------------------------------------------------code starts here.
# -*- coding: utf-8 -*-
from numpy import *
from enthought.mayavi import mlab

# Create the data.
dphi, dtheta = pi/20.0, pi/20.0
[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)

# View it.
s = mlab.mesh(x, y, z, representation="wireframe", line_width=1.0 )

mlab.show()
#--------------------------------------------------------code Ends here.

thank you.
