[vtkusers] Visualising the output of segmentation

[John Hiller]

Hi vtk users

I'm new to vtk and vtk (sorry if this question doesn't apply to vtk).

Okay, so this is what I'm doing:
1) read a dicom series, I process each dicom slice individually
2) pick the segmentation points on a particular dicom slice
3) segment using confidence connected filter and save (or write to a file in
other words) the result to a .mha file
4) Continuously do this for each dicom slice to get series of .mha files
5) Once all that is done, I attempt to use Marching cubes from vtk to render
a 3D surface image from the .mha files.

Everything works with no errors, its just that the vk window comes up black
(showing nothing). I'm pretty sure the .mha files contain something (they're
round about the same size as the original dicom file). I did the cout <<
reader->getOutput(), and it outputs information. I'm presuming that I am
using vtk MarchingCubes incorrectly.

Any advice would be helpful
Thanks
John
