Hello.
Are you using JOGL as the method used by VTK to render to Java panels?
As far as I know, starting from Java 7 (JDK 1.7, i.e., the first non-Apple JDK on MacOS), VTK won’t be able to “directly” render to Java panels through the JAWT interface, due to some changes in the JDK packages/classes and in the related native interfaces.
Hence, right now, the only option left to use VTK with Java on MacOS is by using JOGL (at least, if you need VTK rendering / interaction functionalities).
So, you will need to download JOGAMP, and then build VTK with JOGL options enabled and related CMake settings appropriately setup.
Are you already working this way, i.e., with JOGL?
Regards,
Marco
