[vtkusers] Marching wedge : BUG ?

[Bill Lorensen]

Phillipe,
Thanks for the error report. I've incorporated your corrected cases into the nightly.
I also found cases 43 and 46 to be incorrect. Also, cases 44 and 46 were created
some triangle with the wrong sense.

I've added an example graphics/examplesTcl/marchingWedges.tcl that draws each case.
A proc, cases, takes an argument with a case numebr.

Thanks for your error report.

Bill
