[vtkusers] CO-PLANAR CONTOURS AND SURFACE GENERATION

[Andras Lasso]

Hi Paul,

You can contact the authors (Kyle Sunderland and Csaba Pinter) directly - they would be happy to  help you in using this method. Note that the code that you've found was just a python prototype. More advanced and maintained C++ implementation is available here:

Thanks, once again.

After hours* poring through the SlicerRT source I finally found something useful. For anyone else who comes up against this problem here are some useful links to a solution:

Some heuristics is needed to decide which contour to connect/terminate/branch.

You might give a try to the DICOM-RT importer in 3D Slicer's SlicerRT extension (www.slicerrt.org<http://www.slicerrt.org>). It manages branching, smooth end-capping, etc. If it works for you then you can either use it as is or just have a look at the source code and use it in your own software (the planar contour to closed surface converter only requires VTK).

Hi VTK Users,

I'm currently using vtkRuledSurfaceFilter to convert a sequence of contours into a surface. The problem is that if two contours happen to be on the same plane the surface filter will join them resulting in artefacts.

Any suggestions on how to deal with this?
