Cannot get Sphere VTK example to work.

Hi All!!

So, I am new to VTK. I want to use VTK to visualize and volume render MRI DICOM images.

I have been trying to make the sphere example work (https://vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/Sphere). But with no luck!

I was first trying to make it work on windows. I am using the latest VTK and Cmake versions. I follow the configuration and build steps on the VTK website.

I don’t understand what is happening. I configured and generated the VTK correctly (I think). I checked the VTK_examples.

Could someone help me please :)?

Best regards,
Khalil

Did you build VTK? I see the ccmake but did you build VTK afterward?

Otherwise, your commands look correct. It works for me…

You need to build VTK. I just tried building Sphere against a VTK that has been configured but not built. I get the same bad results you get.

Hi Bill!

Thank you for your reply!

I actually start building the VTK, but I am getting an error that I dont understand:

There is a problem with the current VTK build. If you are using cmake-gui you need to configure VTK as shown here:

Once you do this the build will work.

Also please use: Sphere the link you mentioned has been superseded by the new VTK Examples site.

The problem with ADIOS2 seems to have been fixed now. So you can set the above value back to DEFAULT.

I got the Sphere example to work now I can move on with my project.

That’s good news. Do keep in mind the VTK Examples for inspiration and ideas.
