[vtkusers] Using VTK with Java on Mac OS X

[Mykola Khotyaintsev]

Dear Garsha, Robert, VTK-users and VTK-developers!

I have developed a software based on Java, called the Orbit Visualization
Tool (http://ovt.irfu.se) wich uses VTK. I have compiled VTK with Java
wrapping on Mac OS X, and could get my software running, but unfortunately
with a blank visualization window.

I wrote a couple of times to this mailing list, but my e-mals, as well as
your e.mails, were ignored by everybody. 

That's why I ask the developers - do you know about this problem, and if
so - what is your attitude to it? 

Do you know the reason of this problem and do you have any plan to fix
it?


Looking forward to a reply,

Mykola Khotyaintsev
