[vtkusers] CentOS 6, VTK 6, Qt 5 -- issues with volume rendering and libvtkGUISupportQt

[alketi]

Hi All,

My Setup:  CentOS 6, VTK 6.1.0, Qt 5.2.1

Qt & VTK were both compiled from source and installed in /opt.

I built VTK with cmake, but despite selecting Qt5, many things still tried
to point to the standard Qt4 installation on CentOS.  I hand-corrected as
many of those as I found.

Application Code:  

1.  I have a Qt app and am using a PRO file (not cmake).  My Qt app compiles
and I'm running the vtk-slider demo inside of Qt.  The VTK code uses a
"vtkSphereSource".

2.  The Qt PRO file has includes and libraries pointing to my VTK
installation.

3.  In order to compile successfully, at the top of my CPP I have:
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);  // Added this recently
VTK_MODULE_INIT(vtkInteractionStyle);


MAIN ISSUE:
The main issue is that the Sphere does not render it's front face correctly,
i.e. it doesn't appear fully solid, especially when rotated.  The front face
clips in different ways as you rotate.

In investigating, I noticed that libvtkGUISupportQt-6.1.so is unable to find
any other VTK libraries, even though they all reside in the same directory.

Here's the output from an ldd of /opt/vtk-6.1.0/lib/libvtkGUISupport

Any ideas on what's wrong with the solid object, and why
libvtkGUISupportQt-6.1.so can't find the other VTK libraries that reside
with it?  

And if the two problems are related?

Thanks,
Alketi
