First, thanks for all of your help in getting VTK configured; I really
appreciate it. I'm trying to document this well this in case other users
find this thread. I think that my last question is how to run my
application on other computers that don't have VTK installed (best
method to make the libraries available on the other machines).
Maybe it wasn't necessary in my case to set the path in eclipse, because
I got DemoJavaVTK.java working from
http://www.particleincell.com/blog/2011/vtk-java-visualization/
Maybe it is though in other cases or if I compiled it into a standalone
program. I do have everything set in the Win 7 PATH and CLASSPATH env.
variables.
However, Cone.java from the VTK Examples\Tutorial\Step1Java\Cone still
gives the library errors. There is no dll called vtkCommonJava.dll in
version 6.1.0, but it appears from older internet posts that maybe this
file existed in a previous release of VTK (?). If I comment out the
lines that try to load the following libraries
// static {
// System.out.println(System.getProperty("java.library.path"));
// //System.loadLibrary("vtkCommonJava");
// //System.loadLibrary("vtkFilteringJava");
// //System.loadLibrary("vtkIOJava");
// //System.loadLibrary("vtkImagingJava");
// //System.loadLibrary("vtkGraphicsJava");
// //System.loadLibrary("vtkRenderingJava");
// }
then add a section to load all libraries
static
{
if (!vtkNativeLibrary.LoadAllNativeLibraries())
{
for (vtkNativeLibrary lib : vtkNativeLibrary.values())
{
if (!lib.IsLoaded())
System.out.println(lib.GetLibraryName() + " not loaded");
}
System.out.println("Make sure the search path is correct: ");
System.out.println(System.getProperty("java.library.path"));
}
vtkNativeLibrary.DisableOutputWindow(null);
}
Cone.java works correctly. Some other examples also appear to work
correctly if I repeat the above to load all of the libraries.
