Thanks. The volume rendering seems to work fine with just one problem.
When I rotate an image in a 2d window and get back to the 3d window,
and try to rotate the 3d object, it crashes again.
VTK must be changing the gl state and so I must call resetOpenGLState
before I rotate the view except I can

One of the common ways this crashes the driver is inside calls to
glDrawElements if you have a bad element buffer bound which then indexes into
some random
Thanks so much. I tried a view.resetOpenGLState and it works without
crashing.

Hello,
I'm trying to do volumetric rendering with VTK using the
QVTKFramebufferObject class from
https://gist.github.com/nocnokneo/c3fb01bb7ecaf437f7d6
Essentially this is a class based on QQuickFramebufferObject and over rides
rendering with certain presets for OpenGL states.
It works well for
