mayavi2 bugs

Varun Hiremath
Hi,

I received the following two mayavi2 bugs in Debian:

1/ mayavi2: [regression] interpolated scalar coloring results in black surface
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=550635

2/ mayavi2: gl2ps-generated PDF images are slow and incorrect
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=568684

For some reason, I'm unable to login to enthought trac. It throws this
error message when I try to login:

-------------
Authorization Required

This server could not verify that you are authorized to access the
document requested. Either you supplied the wrong credentials (e.g.,
bad password), or your browser doesn't understand how to supply the
credentials required.
-------------

I tried from two browsers (chrome and firefox) and also tried
resetting password, but nothing helped.

Thanks,
Varun

I cannot reproduce. Could somebody else try. I suspect it might be
graphics-card related. Also, it's most probably a VTK bug, not a Mayavi
bug.

That's clearly not a Mayavi problem. It should probably be moved on to
VTK. However, I suspect that they won't do anything about it: the g;2ps
approach is intrisicly limited.

Thanks for relaying the information, Varun.

No problem here.

The behavior the OP gets looks like to me that he has disabled the
Scalar visibility checkbox, not the Interpolate scalars before mapping
one...


Cheers,
