Building VTK_TRIANGLE 1 with less than three points, but VTK_TRIANGLE needs at least three points. Check the input

This is what I get, and I can not see anything in Mayavi

Thanks.

I can reproduce this. It may be related to this: https://github.com/enthought/mayavi/issues/380

Unfortunately in our case it seems we are already using the VTK 5.10, so I'm not sure what to do about. I'll try to investigate a little.

Actually on the enviroment is

mayavi=4.5.0=py27_0
vtk=6.3.0=py27_1

So I'm not sure what is going on.

[orena1]

Any updates? Thanks.

[mattions]

I'm sorry but my investigation didn't bring any results, and this was done so long time ago as well, I can really follow this up.

Happy to accept PR if you can figure out the problem.
