[vtkusers] Bug in vtkWedge

[Mathieu Westphal]

Hello

As far as i know, vtkWedge are defined like it is explained here :

http://vtk.1045678.n5.nabble.com/vtkWedge-confusion-td1224772.html

so lets i got a normal wedge wich point idx are 0 1 2 3 4 5.

If i switch 3 and 5, i will get twisted wedge.

It displays nicely but fonction like EvaluatePosition seems not to work, 
is it a bug or twisted wedge are not supported?

However, i a rotate one size of the wedge, like 012453, it still works well.

Moreover, it appears there is some bug in vtkWedge :
http://vtk.1045678.n5.nabble.com/Bugs-in-vtkWedge-td1251815.html

This is not been corrected yet  ( 6 years ! ) and the fix proposed by 
the user indeeed fix the contenance of the point but not the computation 
of the distance.

Any idea about that?

Thanks

Mathieu
