[vtkusers] [Java] VTK volume rendering

[Sebastien Jourdain]

Hi Marco,

nothing special happened in that version, but as I recall, on OS X, the
rendering was not properly working due to some native change in the JVM
(can't remember exactly) hence we add a new renderer a while back using
Jogl to create a OpenGL context for us and make it friendly for the Java
UI.

VTK 7, brings new GL calls that are more modern and align with todays
graphic cards, hence I was wondering if something broke/change in regard to
that GL update.
