[IGSTK-Users] vtkVolume display

[Özgür Güler]

Hi Fabian,

in order to render objects in igstk::View you need a "spatial object" and a
"spatial representation", where the first encapsulates geometric
information (e.g. vertices,...)
and the latter controls the color, opacity, etc.

You can use igstk::CTImageSpatialObject as the "spatial object".
For the "spatial representation" you have to implement a new class which
derives from "igstk::ObjectRepresentation".
I think you have already the vtk code for your task. This code has to be
incorporated into this new class. You can take a look at
igstk::ImageSpatialObjectRepresentation and take the parts which deals with
setting the spatial object and other stuff related to igstk's framework.

After that you read in CT data and get an instance of CTImageSpatialObject,
which you pass to your new generated representation class. Then you add the
representation to the view and voila.

Best,
Ozgur
