[vtkusers] How can i view the edges inside an UnstructuredGrid?

[Yasser Bashir]

Hi Longfei,
 
You can use the vtkClipVolume filter to genrerate a tetrahedral mesh
from an image in voxel space.  The output will be an unstructuredgrid
with tetrahedral cells.
 
vtkImageData* image = importer->GetOutput();

//VTK convert image to unstructured grid i.e. tetrahedrons.

cout << "\nClipping Volume"; 

clip = vtkClipVolume::New();

clip->SetInput(image); 

clip->SetValue(0);

clip->Update();

 

 

If this doesnt work for you, try vtkDelaunay3D.

 

Hope this helps.

 

Yasser.

Hi Yasser Bashir£¬

 I am a beginer of VTk. Could you please help me with tetrahedral mesh
generation and give some example about tetrahedral mesh generation.
Thanks a lot!
 Best regards!





Hi,
 
Does any one know a way to display edges inside an unstrucutred grid
when viewing it in the wireframe mode?
 
I know i can extract edges and make them display separately but that
makes the scene very heavy.. 
 
Any help will be greatly appreciated.

Yasser
