[IGSTK-Users] questions on IGSTK

[Patrick Cheng]

Hi Yoav Taieb,

IGSTK can read and display ITK Meshes via igstkMeshReader and 
igstkMeshObjects.

IGSTK is based on ITK & VTK, so you can write a mixed program very 
easily. You can use ITK to read in the images, and use ITK filter to do 
some processing, and then pass the resulting ITK mesh to igstkMeshObject 
and display it in NeedleBiopsy four views. You can also save any 
intermediate results using ITK/VTK writers.

Over all, IGSTK is not designed for image processing and visualization, 
and has very restricted APIs. If you want more flexibility in your 
application for the purposes you have described. You'd better use ITK + 
VTK directly.

You can implement the slice display of CT images like in NeedleBiopsy 
using vtkImagePlaneWidget.
