[vtk-developers] Strange problem with vtkPLYReader

[Prabhu Ramachandran]

Hi all,

We've been running into a strange issue with the vtkPLYReader ever since VTK 5.6
all the way up to 8.0.0.  I am attaching a simple VTK Python script.  If you run
it a few times you'll see inconsistent results for the bounds of the data like so:

(0.0, 1.0, 0.0, 1.0, 0.0, 1.600000023841858)
(0.0, 1.5845632502852868e+29, 0.0, 1.0, 0.0, 1.600000023841858)

...


I've also attached a standard dataset for this.  I could find the bug but I
figured someone more familiar with the code may be quicker fixing it. Thanks! :)


cheers,

Prabhu
