[vtkusers] Theres hole in my Mesh dear Liza, dear Liza!

[Ashika Umanga Umagiliya]

Greetings all,

I use "vtkVoxelContoursToSurfaceFilter"  to generate Mesh from a stack of
contours.
I have this weird case where there is an unsual "hole" in the generated
mesh.

Here is the input "contour data" rendered using OpenGL GL_LINE_STRIP

and here is the generated Mesh

(Note three are two seperate meshes in the scene.Only the outer-bule mesh
has the hole.)

Can anyone think of the reason for this?

Thanks in advane
