Summary

0000599: crash on calc normal to a polygon in 3-D with less than 3 points

Description

I am using VTK 4.4.0 release. This also happend in the versions before.

vtkPolygon.cxx: "$Revision: 1.104 $"

void vtkPolygon::ComputeNormal(vtkPoints *p, int numPts, vtkIdType *pts, double *n)

In this function, sometimes I have int numPts == 1 !! That is
why pts[1] equals -842150451 and I cannot get the correct point
in line 92:

p->GetPoint(pts[1],v2);

And my application crashes. I tried something like:
if ( numPts > 1 ) p->GetPoint(pts[1],v2);
This works and my geometry looks good.
But the loop afterwards
for (i=0; i < numPts; i++)
{
...
}
uses v2 !!

So, there should be some fix in this bug or even that the function is not called for numPts == 1.

best regards,
Ingo
