About contour domains

1

Hello!
Does shapeworks support shape model for 2D shape analysis (Contour based cases)? In the ‘Use cases’ it seems to be OK to analysis shape model for contour domains. But when i import 2D data, Errors jumped out suggesting that the data must be 3D.

Yes, ShapeWorks supports contour data, what file format are you using? @amorris

The types of contours we are currently supporting are as a series of points/lines in VTK files.

Are you trying to use a 2D image segmentation? If so, we can investigate a way to convert it.

Yes，we tried to use 2D shape image segmentation，which was acquired from
3Dslicer. The file format is nrrd and the image is a 2D plane rather than some lines. Is there any tools to convert it？Thank you！

I believe the vtkContourFilter can do this for 2D, but I don’t know that there is a ready-made tool to convert this at the moment.
