Your OpenGL version seems to be sufficient... But, it seems that OpenCL is not available on your machine. Check this: http://streamcomputing.eu/blog/2011-06-24/install-opencl-on-debianubuntu-orderly/ (or other Google links) You probably have to install some drivers to get it to work... Sorry that I cannot be more specific - I am not a Mint user. When you find the solution, would you mind contributing to the wiki?
@royerloic: Do you know whether CUDA is working with the KNIME plugin currently? It might be easier to get it running with CUDA on Linux.
Right now it's hard coded with OpenCL, because we have had too many instability problems with CUDA+Swing (!?). It's very strange, with the latest NVIDIA drivers OpenCL should just work fine... unless there is some issue specific to Mint (ignore previous deleted message which really was about another issue)
@tibuch: We have recently discovered that some Linux distributions cripple the OpenCL libraries that e.g. Nvidia ship. In addition to the driver installed, you also need an ICD (Installable Client Driver), which bridge between the OpenCL libraries and the graphics driver (see e.g. http://stackoverflow.com/questions/29046595/nvidia-opencl-on-trusty-or-mint-17 and https://wiki.tiker.net/OpenCLHowTo). To verify this is setup correctly you can try and run the clinfo
command (of package clinfo). If it doesn't report problems, then ClearVolume should also work. We will document the setup steps better, especially for Linux.
Please let us know if you had any success so we can close this issue :)
Hello I would like to use Clear Volume but get a ExceptionInInitializerError.
I use Linux Mint 17.1 and this is the output of glxinfo:
The exception:
And I have a GeForce GT 220.
If you need any further information let me know.
