Cannot use 3d VTK view in icy

Hi

I am trying to view an image stack in 3d. I get the following error from the VTK Canvas. I cannot select the 3D VTK option that I see in the tutorial files but I do see the 3d glasses which I assume is the replacement icon.

System info
OS - mint LMDE4
GFX card - Nvidia GTX 1060M
memory - 32GB
driver: nivida-driver
java JDK from website
vtk7
my opengl says 3.0

icy on startup

OpenJDK Runtime Environment 1.8.0_242-b08 (64 bit)
Running on Linux 5.9.0-0.bpo.5-amd64 (amd64)

System total memory : 32.6 GB

VTK 6.3.0 library successfully loaded…

Icy Version 2.1.2.0 started !

*** UPDATE***
Switch to the java package on the website. I can click the 3d glasses but ICY crashes completely. I get a vtk log with the following

Warning: In /home/stephane/Documents/dev/vtk/6.3/source/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 428

I also have this hs_error file that is quite large that as a core dump.

OK so the switch to the correct openjdk-8 allows me to see the 3d VTK option that was just missing with openjdk-11. This error message suggest that ICY as a program is using the wrong openGL profile.

So I have a version of opengl installed that should be compatible. If I set the environmental variable to
MESA_GL_VERSION_OVERRIDE to a value that is greater than 3.2, I avoid the hard crash. All I get is a blank screen instead of render. No error log is generated. I feel this is a bug on between VTK and opengl but not sure what to do next.

@Stephane ← I am just tagging you to let you know that this issue extends to Linux. I saw the discussion on the other thread for MacOS and I just want to make sure Linux users are also in your purview. I think it is the exact same issue with JOGL and the vtk needing updating. I get the same error on windows.

Thanks @cell789 !
Indeed i think this is an issue related to the old OpenGL / JOGL library we are using (because of the old VTK library version). When we will upgrade VTK we will also make sure that everything is alright for Linux as well. Thanks again for pointing it :slight_smile:
Unfortunately i think there is no workaround except waiting for the next version…

Regards,

Thank you for your response. I love ICY! eagerly awaiting the update so I can take my analysis to the 3rd dimension!

Hi

Do we have a rough estimate on when the next version of ICY would be released? Do you have a docker image that works as a stop gap?

Hi @cell789

We are currently working on it but it may take some time, we hope to be able to deliver it that month.
Reading back your issue specifically, it looks your video driver return an OpenGL version of 3.0 while VTK require 3.2 at least. That seems to be related to this error:

I’m not sure you can update your graphics card driver to have a proper OpenGL 4.0 support (the graphics card support up to 4). Still building a new version of VTK, we should be able to setup that so hopefully the minimum requirement is lower than 3.2.

Best,

– Stephane
