Hi Dora,
sorry for the late reply. I am not sure what the cause might be. It seems to be
on our side, so it might be due to specific options we set on the rendering
context that differ from the default vtk options. It could be helpful to know
the hardware and openGL specs for your systems.
You could try changing some of the surface rendering properties to narrow down
the culprit. (Just open the properties view and change e.g. the
materal.Interpolation method)
Best,
Caspar

Dear Casper,
I just created a standalone app to visualise the same mesh with VTK alone and
it seems fine (attached screenshot). The VTK version I used was the exact same
as what comes with MITK 2016.3.0 super build.
It appears that something in the MITK 2016.3.0 renderer window is not happy
with my version of Ubuntu 16.04. I tested the same mesh both on a laptop and a
desktop with Ubuntu 16.04 and they both had the same issue. They both have a
clean newly installed version of Ubuntu. The exact same setup on older Ubuntu
14.04 doesn't suffer from the issue.
Any ideas what I should be looking at?
Many thanks as always.

Hi Dora,
it might be something with the way we render surfaces. It might also be
something with VTK itself. Could you render the surface in VTK directly and
report whether the same thing happens there?
I have opened a task for it [1]. Even if it is a VTK issue it would be
interesting to know your laptops graphics chip.
Best,
Caspar

Betreff: [mitk-users] VTK mesh rendering issue
Hi everyone,
I load a simple VTK mesh in MITK 2016.03 and the 3D view has issues rendering
it properly. By rotating the mesh around half of its surface become transparent
for no reason and you can see the other side of the mesh. I attached a
screenshot too.
This doesn't happen to me on my Linux desktop but only on the Linux Ubuntu
laptop, so I guessed maybe there is something wrong with my graphics card
driver but the same mesh on the same laptop renders normally on Paraview for
instance.
Any ideas?
Many thanks
Dora
