[Insight-developers] ImageViewer and GLUT

[Luis Ibanez]

Hi Jim,

Yeap, as you already mention,
unfortunately GLUT doesn't seem to be installed
by default on Windows.

I installed it on Windows using the sources from
Nate Robins:

     http://www.xmission.com/~nate/glut.html

On Linux it is usually part of a standard distribution.

This itk::ImageViewer<> is an attempt to provide a
minimum image viewer for examples. Hopefully that will
make the itk::HelloWorld more appealing.

GLUT is the last desperate attempt before being forced
to print the pixels as ascii characters   :-)

-------

The use will look like:


typedef itk::Image<char,3>  ImageType;
typedef itk::ImageViewer< ImageType >  ViewerType;

ViewerType::Pointer  viewer = ViewerType::New();

viewer->SetInput( filter->GetOutput() );

viewer->Update();  // equivalent to viewer->Show();


ViewerType::StartInteraction();   // start the loop event.



The viewer is based on the GlutMaster classes written by
George Stetten. GlutMaster was ITK-ized and included in
the Insight/Utilities directory.

There are still some minor issues with the 3D images.
2D are working Ok.

This is a truly minimal viewer, no fancy features....
no zoom, no intensity windowing,..

Keyboard an mouse interaction (e.g. pixel picking)
are available though.

In the past with lab software, we manually installed Glut. Not sure if =
it still applies in itkLand, but here's how:

The GL subdirectory is in Visual Studio's include path:
X:\....\Microsoft Visual Studio .NET\Vc7\include\GL    --> move glut.h =
here

X:\....\Program Files\Microsoft Visual Studio .NET\Vc7\lib  --> move =
glut.lib here

Put glut.dll in the system32 directory.

   Luis,

   I tried to use the glut image viewer that you are piecing together.  I =
hit upon the following issues:
     1.. Developer Studio .Net does not include glut in the default =
installation.  I didn't have my CD's with me last night to see if it is =
somewhere on the installation disk.  However, given MS's relationship =
with OpenGL, I would not be surprised if they no longer distribute glut. =

     2.. I downloaded a win32 binary installation of glut. FindGLUT.cmake =
of course did not find my new installation, so I told CMakeSetup where =
the glut.lib was.  Unfortunately, the binary installation of glut is =
just a directory with  "glut.h", "glut.lib", and a "glut.dll".  So when =
GlutMaster tries to include "GL/glut.h" is cannot find glut.h because =
the header is not in a subdirectory "GL".=20
     3.. I don't think my FindGLUT.cmake file sets ups a variable for the =
defining where the include directory for glut.h would be on a win32 =
system.=20
     4.. FindGLUT.cmake defines GLUT_LIBRARY but your CMakeLists.txt file =
references GLUT_LIBRARIES
    After this I lost interest and went about using VTK to view my =
images.=20
